In the modern construction industry, the safety and reliability of electrical systems are paramount, especially in residential settings where the well-being of occupants is directly at stake.
Electrical Wires and cables serve as the lifelines of any household’s electrical infrastructure, facilitating the seamless transmission of electricity to power various appliances, lighting, and other electrical devices. Recognizing the critical role these components play, our company is proud to offer a range of EU-certified electrical wires and cables specifically designed for house wiring, with a focus on 1.5mm and 2.5mm specifications. These products are engineered to meet the highest standards of safety, performance, and compliance, making them the ideal choice for homeowners, contractors, and builders across Europe and beyond.
Our 1.5mm and 2.5mm electrical wires and cables are not just ordinary conductors of electricity; they are the result of extensive research, advanced manufacturing processes, and a commitment to quality. Every aspect of their design and production is meticulously planned to ensure they can withstand the rigors of daily use in a household environment, while also adhering to the strict regulations set forth by the European Union. Whether it is a new home construction project, a renovation, or a simple wiring upgrade, our products provide a reliable and safe solution that stands the test of time.
EU certification, particularly the CE marking, is more than just a label; it is a guarantee that a product meets the essential requirements of the relevant European directives and regulations. For electrical wires and cables used in house wiring, this certification is a testament to their compliance with stringent health, safety, and environmental protection standards. The CE marking indicates that the product has undergone a thorough assessment process, including testing, documentation review, and quality control checks, to ensure it poses no unacceptable risks to users or the environment.
In the context of electrical products, the CE marking is governed by several key directives, including the Low Voltage Directive (LVD) 2014/35/EU, which applies to electrical equipment designed for use within certain voltage limits (50V to 1000V for alternating current and 75V to 1500V for direct current). Our 1.5mm and 2.5mm wires and cables fully comply with the LVD, ensuring they are safe for use in residential electrical systems. Additionally, they adhere to the Construction Products Regulation (CPR) (EU) 305/2011, which sets out the requirements for construction products, including electrical wires and cables used in building projects. The CPR mandates that these products must be assessed for their performance characteristics, such as mechanical strength, fire resistance, and durability, and carry a CE marking along with a Declaration of Performance (DoP).
To achieve EU certification, our electrical wires and cables must comply with specific European standards (EN standards) that define their technical requirements and test methods. For
House Wiring Cables, the primary standard is EN 50575:2014, "Power, control and communication cables – Cables for general applications in construction works subject to reaction to fire requirements." This standard specifies the performance criteria for cables used in construction, with a particular focus on their reaction to fire.
EN 50575 classifies cables into different categories based on their fire performance, including classes such as B1, B2, C, D, E, and F, where B1 represents the highest level of fire resistance. Our 1.5mm and 2.5mm cables are classified under the appropriate fire performance classes as required by the CPR, ensuring they meet or exceed the minimum requirements for use in residential buildings. This classification is determined through a series of rigorous tests, including:
Heat release test: Measures the amount of heat released by the cable during combustion, which is crucial for assessing the potential spread of fire.
Smoke production test: Evaluates the density and toxicity of smoke generated by the cable when burning, as excessive smoke can hinder evacuation and cause respiratory problems.
Flame propagation test: Determines how far and how quickly a flame spreads along the cable, helping to prevent the fire from spreading to other parts of the building.
Acidity test: Analyzes the acidity of the gases produced during combustion, as corrosive gases can damage electrical equipment and pose a risk to human health.
By complying with EN 50575 and other relevant EN standards, our cables demonstrate their ability to perform safely in the event of a fire, providing valuable time for occupants to evacuate and minimizing damage to property.
Obtaining EU certification is a rigorous and multi-step process that involves collaboration between our company and accredited third-party testing laboratories and notified bodies. The process typically includes the following stages:
Product Design and Development: Our engineering team designs the wires and cables based on the requirements of the relevant EU directives and EN standards. This includes selecting appropriate materials, determining the conductor size and insulation thickness, and ensuring the overall design meets performance criteria.
Testing: Samples of the cables are sent to accredited testing laboratories for a series of tests to verify their compliance with the standards. These tests cover electrical performance (such as conductivity and insulation resistance), mechanical properties (such as Flexibility and tensile strength), and fire resistance, among others.
Documentation Review: We prepare a technical file that includes detailed information about the product, such as design drawings, test reports, manufacturing processes, and quality control procedures. This file is reviewed by a notified body to ensure it provides sufficient evidence of compliance.
Quality Control System Assessment: The notified body assesses our quality control system to ensure that we have processes in place to consistently produce cables that meet the required standards. This includes checking our manufacturing facilities, production processes, and inspection procedures.
Issuance of Certification: If the product passes all tests and the documentation and quality control system are deemed satisfactory, the notified body issues a certificate of conformity, allowing us to affix the CE marking to our cables.
This comprehensive certification process gives our customers confidence that our 1.5mm and 2.5mm electrical wires and cables are safe, reliable, and compliant with all applicable EU regulations.
The specification of an electrical wire, denoted by its diameter in millimeters (mm), is a critical factor that determines its current-carrying capacity, resistance, and suitability for specific applications. In house wiring, 1.5mm and 2.5mm are the most commonly used gauges, each designed to handle different electrical loads.
The diameter of the wire is directly related to its cross-sectional area, which in turn affects its ability to conduct electricity. A larger cross-sectional area ( thicker wire) allows for a higher current to flow through it without overheating, as it has lower resistance. Conversely, a smaller cross-sectional area (thinner wire) has higher resistance and is suitable for lower current applications.
The 1.5mm wires in our product range are specifically designed for use in lighting circuits, where the electrical load is relatively low. Lighting fixtures, such as ceiling lights, wall sconces, and table lamps, typically draw a small amount of current, making 1.5mm wires the perfect choice.
One of the key advantages of 1.5mm wires is their flexibility. They are easy to bend and maneuver, which is essential when wiring through tight spaces, such as between ceiling joists, inside walls, or around corners. This flexibility simplifies the installation process, reducing the time and effort required by electricians.
In terms of current-carrying capacity, 1.5mm wires are capable of handling currents up to approximately 16 amps (A) in typical household installations. This is sufficient for most lighting circuits, which usually have a maximum load of around 3.5 kilowatts (kW) (based on a 230V supply, power = voltage x current, so 230V x 16A = 3680W). This allows for multiple light fixtures to be connected to a single circuit without exceeding the wire’s capacity.
It is important to note that the current-carrying capacity can vary depending on factors such as the installation method (e.g., enclosed in a conduit, buried in plaster, or exposed), the ambient temperature, and the number of wires bundled together. Our 1.5mm wires are designed to handle these variations, ensuring safe operation under normal household conditions.
The 2.5mm wires are thicker and more robust than the 1.5mm version, making them suitable for applications that require a higher current-carrying capacity. They are commonly used for power outlets, which supply electricity to small to medium-sized appliances such as refrigerators, televisions, microwaves, and vacuum cleaners.
2.5mm wires can handle currents up to approximately 25 amps (A) in typical installations, which corresponds to a maximum load of around 5.75 kW (230V x 25A = 5750W). This higher capacity ensures that multiple appliances can be connected to a single power outlet circuit without causing the wire to overheat, which could lead to a fire hazard.
Like the 1.5mm wires, the current-carrying capacity of 2.5mm wires can be affected by installation conditions. For example, if the wires are installed in a hot environment or are bundled with other wires, their capacity may be reduced. However, our 2.5mm wires are engineered to maintain their performance under a wide range of conditions, providing reliable power to household appliances.
Both 1.5mm and 2.5mm wires are compatible with standard household electrical systems, which typically operate at 230V alternating current (AC) in Europe. They can be used with various types of switches, sockets, and distribution boards, ensuring seamless integration into any residential wiring setup.
When designing a house wiring system, electricians carefully calculate the electrical load for each circuit and select the appropriate wire gauge to ensure safety and efficiency. Our 1.5mm and 2.5mm wires provide the flexibility and performance needed to meet these requirements, making them a versatile choice for any household.
The conductor is the core component of an electrical wire, responsible for carrying the electrical current. Our 1.5mm and 2.5mm wires use high-quality copper as the
Conductor Material, and for some variants, the copper is tinned to enhance its performance and longevity.
Copper is widely regarded as the ideal material for
Electrical Conductors due to its excellent electrical conductivity. It has a low electrical resistance, which means less energy is lost as heat during the transmission of electricity, making the wiring system more efficient. Additionally, copper is highly ductile and malleable, allowing it to be drawn into thin wires without breaking, which is essential for producing wires of precise gauges like 1.5mm and 2.5mm.
Tinned
Copper Conductors offer additional benefits. The tin coating provides a protective layer that prevents the copper from corroding, especially in humid or damp environments. Corrosion can increase the resistance of the conductor, reducing its conductivity and potentially leading to overheating. Tinned copper also improves the solderability of the wire, making it easier to connect to terminals and other components during installation.
The conductors in our wires are stranded, meaning they consist of multiple small
Copper Strands twisted together, rather than a single solid core.
Stranded Conductors offer greater flexibility than solid conductors, which is particularly important for house wiring where the wire needs to be bent and routed through various spaces. The stranding also improves the wire’s durability, as it can withstand repeated flexing without breaking.
The
Insulation Material surrounding the conductor is crucial for preventing electrical leakage, short circuits, and electric shock. Our 1.5mm and 2.5mm wires use Polyvinyl Chloride (PVC) as the primary insulation material, chosen for its excellent combination of properties.
PVC is a thermoplastic polymer that offers several advantages for electrical insulation:
Electrical insulation properties: PVC has high dielectric strength, which means it can withstand high voltages without allowing electrical current to pass through it, effectively preventing short circuits and leakage.
Flame retardancy: Our PVC Insulation is formulated to be flame retardant, meaning it resists ignition and slows down the spread of fire. This is in line with the fire performance requirements of EN 50575 and the CPR, enhancing the safety of the wiring system in case of a fire.
Chemical Resistance: PVC is resistant to a wide range of chemicals, including oils, solvents, and acids, which helps to protect the conductor from damage in various household environments.
Moisture resistance: The insulation provides a barrier against moisture, preventing water from coming into contact with the conductor and causing corrosion or electrical faults.
Durability: PVC is a tough and durable material that can withstand the mechanical stresses of installation and daily use, ensuring the insulation remains intact over the long term.
The thickness of the insulation is carefully controlled to meet the requirements of the relevant standards. It is designed to provide adequate protection while keeping the overall diameter of the wire manageable, allowing for easy installation in conduits and other tight spaces.
In addition to insulation around individual conductors, our cables (which consist of multiple
Insulated Conductors) are often covered with an outer sheathing, also made of PVC. The sheathing provides an extra layer of protection, bundling the conductors together and shielding them from external damage, such as impact, abrasion, and exposure to sunlight.
The outer sheathing also plays a role in fire resistance, as it is formulated to be flame retardant, complementing the insulation of the individual conductors. It helps to maintain the integrity of the cable during a fire, reducing the risk of the conductors being exposed and causing further hazards.
The manufacturing of our 1.5mm and 2.5mm electrical wires and cables involves a series of precise processes to ensure consistent quality:
Copper rod drawing: High-purity copper rods are drawn through a series of dies to reduce their diameter and form the individual copper strands. This process ensures the strands have the correct size and mechanical properties.
Stranding: The copper strands are twisted together to form the conductor, using specialized machinery that ensures uniform stranding and optimal flexibility.
Insulation extrusion: The stranded conductor is passed through an extrusion machine, where molten PVC is applied around it to form the insulation layer. The extrusion process is carefully controlled to ensure the insulation has a uniform thickness and adheres tightly to the conductor.
Cabling (for multi-Conductor Cables): For cables with multiple insulated conductors, the conductors are twisted or laid up together, and an outer sheathing is extruded around them using a similar extrusion process.
Testing: Each batch of wires and cables undergoes rigorous testing to check for electrical performance (conductivity, insulation resistance), mechanical properties (tensile strength, flexibility), and fire resistance. This ensures that only products that meet our strict quality standards are released to the market.
These advanced manufacturing processes, combined with the use of high-quality materials, result in electrical wires and cables that are reliable, durable, and safe for use in house wiring.
