I. Product-specific Information
(1) Specifications and Parameters
The specifications and parameters of the black PE outdoor telephone cable (2-core parallel 2×0.80mm
Copper Drop Wire for overhead application) are carefully designed to meet the needs of outdoor overhead telephone communication.
In terms of conductor specifications, the cable adopts a 2-core parallel design, with each conductor having a cross-sectional area of 0.80mm². This specification of conductor can ensure the stable transmission of telephone signals while taking into account the
Flexibility and installation convenience of the cable. The diameter of the
Copper Conductor is accurately calculated to ensure that its conductivity meets the communication industry standards, and the signal attenuation during transmission is controlled at an extremely low level to ensure clear call quality.
In terms of electrical performance, the cable has an extremely high insulation resistance, which can effectively prevent current leakage and ensure the safety and stability of signal transmission. Its working voltage meets the standard requirements of telephone communication lines and can operate stably for a long time in the conventional telephone communication voltage environment. In addition, parameters such as capacitance and inductance of the cable have also undergone strict testing to ensure that there will be no excessive signal distortion and interference during signal transmission.
Mechanical performance parameters are also not to be ignored. The cable has moderate tensile strength, which can bear its own weight and a certain external tension during overhead installation and use, and is not easy to break. It has good bending performance, with a minimum bending radius of not less than 8 times the outer diameter of the cable, which is convenient for laying and installation in complex overhead environments. At the same time, the cable has a certain impact resistance, which can resist minor collisions and vibrations that may be encountered outdoors.
(2) Characteristic Applications
This black PE outdoor telephone cable has a wide range of characteristic applications in many fields due to its unique performance.
In the construction of urban communication networks, it is an ideal choice for outdoor telephone line erection. There are many high-rise buildings in cities, and
Overhead Lines need to adapt to complex spatial environments. The 2-core parallel design and good flexibility of the cable enable it to easily cross the gaps between streets and buildings, providing stable telephone communication services for urban residents and commercial institutions. Whether in prosperous commercial areas or densely populated residential areas, it can reliably transmit telephone signals.
The telephone line connection in rural areas is also inseparable from this cable. The terrain in rural areas is complex, and some areas are inconvenient in transportation. The overhead laying method is relatively simple, which can reduce the construction difficulty and cost. The cable has strong weather resistance and can be used for a long time in the open environment in rural areas, resisting the influence of natural factors such as wind, sun, rain and so on, so as to ensure smooth telephone communication between rural residents and the outside world.
It is also suitable for outdoor communication wiring in industrial parks. There are a large number of enterprises and factories in industrial parks, which have high requirements for communication stability. The cable can adapt to the industrial environment of the industrial park, not affected by factors such as vibration and electromagnetic interference generated by machine operation, and provide reliable telephone communication support for production scheduling and business contact of enterprises in the park.
This cable can also play an important role in outdoor communication wiring of residential communities. It can be laid overhead from the communication room of the community to each building, providing signal transmission lines for fixed telephones in residents' homes. Its black appearance is coordinated with the outdoor environment of the community and will not affect the overall beauty of the community.
(3) Material and Style
Material
Conductor: High-purity electrolytic copper is used as the Conductor Material. Electrolytic copper has extremely high conductivity, which can ensure minimal loss of telephone signals during transmission and ensure the clarity and stability of signals. At the same time, copper has good ductility and plasticity, which is easy to be processed into wires with uniform diameter, and is not easy to break during bending and stretching, so it can adapt to the needs of overhead installation.
Insulation layer: High-quality polyethylene (PE) material is selected as the insulation layer. PE material has excellent electrical insulation performance, which can effectively isolate current interference between the two conductors and between the conductor and the outside world, ensuring that signal transmission is not affected. In addition, PE material has good chemical stability, acid and alkali corrosion resistance, and is not easy to be eroded by outdoor pollutants. It has strong weather resistance, can resist ultraviolet radiation, high and low temperature changes, and maintain good performance in the ambient temperature range of -40℃ to 60℃, extending the service life of the cable.
Outer sheath: Although the insulation layer of the cable also plays a certain protective role, the PE material itself also has certain mechanical strength, which can provide certain protection for the internal copper conductor and prevent slight mechanical damage during erection and use.
Style
The cable adopts a 2-core parallel design. The two
Copper Conductors are arranged parallel to each other, and the outside is wrapped with a black PE insulation layer to form a whole. This parallel design makes the structure of the cable simple, easy to arrange and fix during laying, and is especially suitable for overhead installation. The cable has a small outer diameter and light weight, which reduces the load pressure during overhead erection and is also convenient for transportation and storage. The black appearance not only has good dirt resistance, but also is not easy to absorb heat in the outdoor environment, which can reduce the impact of excessive temperature on the cable performance.
(4) Production Process
The production process of the black PE outdoor telephone cable (2-core parallel 2×0.80mm copper drop wire for overhead application) is rigorous and meticulous to ensure that the product quality meets relevant standards.
First is the preparation of copper conductors. High-purity electrolytic copper ingots are made into copper rods through smelting, casting and other processes, and then the copper rods are drawn into
Copper Wires with the required diameter through a wire drawing machine. During the wire drawing process, it is necessary to strictly control the wire drawing speed and the precision of the die to ensure that the diameter of the copper wire is uniform and the surface is smooth, so as to ensure its electrical conductivity and mechanical properties.
Next is the extrusion molding of the insulation layer. The extruder is used to heat and melt the PE particles, and then uniformly wrap them on the surface of the copper wire through a die to form the insulation layer. During the extrusion process, it is necessary to accurately control the extrusion temperature, pressure and speed to ensure that the thickness of the insulation layer is uniform, closely combined with the copper wire, and free of defects such as bubbles and pinholes. For the 2-core parallel structure, through the design of a special die during extrusion, the two copper wires wrapped with the insulation layer are kept in a parallel state to form the overall cable structure.
After extrusion molding, the cable is cooled to make the PE insulation layer solidify and shape quickly. The cooling method usually adopts water cooling to ensure that the appearance of the cable is flat and the size is stable.
Then is the quality inspection link. Sampling inspection is carried out on the conductor diameter, insulation layer thickness, insulation resistance, voltage resistance and other properties of the cable to ensure that each batch of products meets the quality standards. At the same time, the appearance of the cable is inspected to ensure that the surface is smooth, free of scratches and damage.
Finally, the qualified cables are wound into coils according to a certain length to form finished products. During the winding process, the tension should be well controlled to avoid excessive stretching or twisting of the cable, which may affect its performance.
II. General Product Information
(1) Packaging
To ensure that the cable is not damaged during transportation and storage, the cable adopts a reasonable packaging method.
Usually, the cable will be wound on a plastic or wooden reel, and the size of the reel is determined according to the length and diameter of the cable. The two sides of the reel are provided with baffles to prevent the cable from sliding off during transportation. For cables with shorter lengths, they can also be packaged in coils, tightly wrapped with plastic film, and then covered with woven bags or cartons to protect the cable from dust, moisture and mechanical damage.
The packaging will clearly mark the product name, specification model, length, production date, implementation standard, manufacturer and other information, which is convenient for customers to identify and accept. At the same time, warning signs such as "Handle with care", "Moisture-proof" and "Sun-proof" will be printed to remind transportation and storage personnel of relevant matters.
(2) Transportation
Transportation methods: According to the order quantity and transportation distance, different transportation methods can be selected. For small batch and short-distance transportation, road transportation is usually used, and trucks are used to transport the packaged cables to the destination. For large batch and long-distance transportation, railway transportation or logistics 专线 can be selected to reduce transportation costs and improve transportation efficiency.
Transportation precautions: During transportation, it is necessary to avoid severe vibration, collision and extrusion of the cable to prevent damage to the insulation layer and conductor of the cable. The transport vehicle should drive smoothly, avoiding sudden braking, sharp turns and other operations. The cable should be stored in a dry and ventilated carriage to avoid rain, moisture and exposure to the sun. For cables wound on the reel, the reel should be placed horizontally, and it is strictly forbidden to invert or tilt to prevent the cable from loosening. Cables of different specifications and models should be stacked separately to avoid confusion.
