Detailed Introduction to LSZH Halogen-Free Flexible Flame-Retardant Low-Smoke Electrical Wire - Thermoplastic Building Wire for Residential Wiring Projects
I. From the Perspective of the Product Itself
(1) Specification Parameters
This LSZH halogen-free flexible flame-retardant low-smoke electrical wire has been carefully designed in terms of specification parameters to meet the diverse needs of residential wiring projects.
There is a wide range of wire diameter specifications, commonly including 0.5mm², 0.75mm², 1mm², 1.5mm², 2.5mm², 4mm², 6mm², etc. Different wire diameters correspond to different current-carrying capacities. Wires of 0.5mm² and 0.75mm² are usually suitable for low-power lighting circuits, such as chandeliers and wall lamps in bedrooms and living rooms; wires of 1mm² and 1.5mm² can be used for ordinary socket circuits, connecting small appliances such as TVs, computers, and desk lamps; wires of 2.5mm² are suitable for appliances with slightly higher power, such as air conditioners and electric water heaters; wires of 4mm² and 6mm² are mostly used for incoming lines and special circuits for high-power appliances, such as central air conditioners and instant electric water heaters.
The rated voltage is 450/750V, which meets the voltage requirements of residential electrical systems, and can stably provide power support for various electrical equipment in the residence, ensuring that the equipment operates safely under normal working voltage.
The insulation thickness varies according to the wire diameter. The smaller the wire diameter, the relatively thinner the insulation thickness; the larger the wire diameter, the corresponding increase in insulation thickness. Generally speaking, the insulation thickness of 0.5-1mm² wires is about 0.6-0.8mm, that of 1.5-2.5mm² wires is about 0.8-1.0mm, and that of 4-6mm² wires is about 1.0-1.2mm. A suitable insulation thickness can not only ensure good insulation performance but also keep the wire flexible to facilitate construction and installation.
The conductor is made of high-purity copper, and the conductor structure is divided into single-strand and multi-strand. The single-strand conductor is composed of a relatively thick
Copper Wire, with relatively high hardness, suitable for fixed wiring; the multi-strand conductor is formed by stranding multiple thin copper wires, with better
Flexibility, more suitable for occasions that require frequent bending or movement.
(2) Characteristic Uses
In addition to being suitable for power connection of conventional electrical equipment such as lighting, sockets, air conditioners, and refrigerators in residences, this wire has many characteristic uses.
It can play an important role in the wiring of smart home systems. With the development of smart homes, various smart devices need to be connected in residences, such as smart switches, smart sensors, smart curtain motors, etc. The wiring of these devices has high requirements for the safety and stability of wires. The halogen-free, flame-retardant, and low-smoke characteristics of this wire can ensure the safety of the smart home system during long-term use, and even in case of accidents, the loss can be minimized.
For residential areas with high environmental requirements, such as children's rooms and elderly rooms, this wire is an ideal choice. Children and the elderly have relatively weak physical resistance and poor tolerance to toxic substances and smoke. The characteristic of this wire that it does not release toxic gases and produces little smoke when burning can provide them with a safer living environment.
In the wiring of large-area residences such as villas and duplex buildings, due to the long wiring lines and many branches, the construction difficulty is relatively large. However, this wire has good flexibility, can easily cope with complex wiring environments, improve construction efficiency, and its stable performance can also ensure the reliability of power transmission during long-distance transmission.
In addition, this wire can also meet the needs in the secondary decoration or line transformation of residences. The lines of old residences often have problems such as aging and decreased insulation performance. After replacing with this wire, the safety and stability of the residential electrical system can be improved, providing more reliable power guarantee for residents' lives.
(3) Material and Style
Conductor Material: High-purity electrolytic copper is used, with a purity of more than 99.9%. High-purity copper has excellent conductivity, which can reduce losses during current transmission and improve power use efficiency. At the same time, copper has good ductility, which is convenient for processing into conductors of different specifications. Both single-strand and multi-strand structures can ensure good mechanical properties.
Insulation layer material: LSZH (halogen-free low-smoke flame-retardant) material is used, which is a thermoplastic material that does not contain halogens (fluorine, chlorine, bromine, iodine, astatine). It has excellent flame-retardant performance, can form a carbonized layer under the action of flame to prevent flame spread; at the same time, it produces little smoke when burning, and the smoke does not contain toxic gases, meeting environmental protection and safety requirements. In addition, this material also has good chemical corrosion resistance and anti-aging performance, and can adapt to various environmental conditions in residences.
Style design: The wires have various colors, commonly including red, blue, yellow, green, black, etc. Wires of different colors can be used to distinguish different circuits, such as live wires, neutral wires, Ground Wires, etc., which is convenient for construction personnel to identify and install, and reduces the probability of wiring errors. The appearance of the wire is smooth and flat, without burrs, bubbles and other defects, and the overall texture is good.
(4) Production Process
The production process of this LSZH halogen-free flexible flame-retardant low-smoke electrical wire is strict and precise to ensure product quality.
Conductor manufacturing: First, high-purity copper raw materials are smelted to remove impurities, and then made into copper rods through continuous casting. The copper rods are drawn into copper wires of different diameters through wire drawing process. For multi-strand conductors, multiple copper wires need to be stranded according to a certain stranding method. During the stranding process, the stranding pitch should be controlled to ensure the roundness and flexibility of the conductor.
Insulation layer extrusion: The extrusion molding process is used to wrap the LSZH insulation layer outside the conductor. The LSZH material is heated to a molten state and uniformly coated on the surface of the conductor through the die of the extruder. During the extrusion process, the extrusion temperature, speed and pressure should be precisely controlled to ensure that the insulation layer has uniform thickness, smooth surface, close combination with the conductor, and no defects such as bubbles and pinholes.
Cooling and solidification: The extruded wire enters the cooling water tank for cooling to make the insulation layer quickly solidify and form. During the cooling process, the water temperature should be controlled to avoid internal stress in the insulation layer caused by too fast cooling speed, which affects the performance of the wire.
Spark detection: The cooled wire is subjected to spark detection, and the insulation layer is detected for breakdown and other defects through high-voltage electricity to ensure that the insulation performance of the wire meets the standards.
Take-up and packaging: The wires that pass the inspection are taken up according to a certain length. During the take-up process, the tension should be kept uniform to avoid stretching or twisting of the wires. Finally, packaging is done, waiting for delivery.
II. From the Perspective of General Product Information
(1) Packaging
In order to ensure the quality of the wire during transportation and storage, a scientific and reasonable packaging method is adopted.
For small-sized and short-length wires, plastic reel packaging is usually used. The reel is made of high-strength plastic, which has certain compression resistance and moisture resistance. The wires are neatly wound on the reel, and baffles are set at both ends of the reel to prevent the wires from slipping off. The reel is marked with product name, specification, length, production date, batch number and other information, which is convenient for customers to identify and manage.
For large-sized and long-length wires, wooden reel packaging is adopted. The wooden reel is made of high-quality wood, with high strength and can bear large weight. After the wire is wound on the wooden reel, it is wrapped with plastic film to play a role in moisture-proof and dust-proof. The side of the wooden reel is also marked with detailed product information and is easy to be handled by forklifts and other equipment.
Whether it is plastic reel or wooden reel packaging, eye-catching warning signs such as "怕湿 (afraid of moisture)" and "轻放 (handle with care)" are pasted on the outside of the package to remind transportation and storage personnel to pay attention to relevant matters.
(2) Transportation
