Details of 18/2 22/2 Gauge One Pair 2X0.8mm 2X1.0mm PE Insulation Copper Outdoor Aerial Twin Parallel Telephone Drop Wire

I. Product-specific Information

(1) Specifications and Parameters

The 18/2, 22/2 gauge one pair 2×0.8mm, 2×1.0mm PE insulation copper outdoor aerial twin parallel telephone drop wire has clear and detailed settings in terms of specifications and parameters to ensure stable transmission of outdoor telephone signals.

In terms of conductor specifications, the 18/2 gauge corresponds to a conductor cross-sectional area of 2×0.8mm, and the 22/2 gauge corresponds to 2×1.0mm. The "2×" here indicates that the telephone drop wire has a twin-core structure, and each core wire undertakes different roles in signal transmission, together forming a complete communication loop. The difference in cross-sectional areas of 0.8mm and 1.0mm results in different current-carrying capacities between the two gauges. At standard ambient temperature, the current-carrying capacity of the 2×0.8mm gauge conductor is approximately 5A, and that of the 2×1.0mm gauge is about 7A. This means that the 2×1.0mm gauge can maintain better signal strength in longer-distance signal transmission, while the 2×0.8mm gauge is suitable for short-distance signal transmission scenarios.

In terms of electrical performance parameters, the working voltage of this telephone drop wire meets the standard requirements of telephone communication lines, usually below 50V, which can meet the voltage demand for ordinary telephone signal transmission. Insulation resistance is an important indicator to measure its insulation performance. At 20℃, the insulation resistance value is not less than 1000MΩ·km, which ensures good insulation between core wires and between core wires and the outside world, effectively avoiding signal interference and leakage. In addition, its capacitance and inductance values are precisely controlled, which can reduce signal reflection and attenuation during signal transmission, ensuring clear call quality.

Mechanical performance parameters are also not to be ignored. Both gauges of telephone drop wires have a certain tensile strength. The tensile strength of the 2×0.8mm gauge is not less than 150N, and that of the 2×1.0mm gauge is not less than 200N. This enables them to withstand the tension generated by their own weight and external wind force during aerial installation and use, and are not easy to break. In terms of bending performance, the minimum bending radius is not less than 10 times the outer diameter of the cable, which is convenient for erection and installation in complex outdoor environments without damaging the internal structure due to excessive bending.

(2) Characteristic Applications

This PE insulation copper outdoor aerial twin parallel telephone drop wire has characteristic applications in multiple scenarios due to its unique performance.

In urban fringe areas, due to urban expansion and the extension of communication networks, it is necessary to introduce telephone signals from the main line to newly developed residential areas or commercial areas. The outdoor aerial design of this telephone drop wire can adapt to the relatively complex terrain in urban fringe areas, and can be erected on carriers such as electric poles and walls to achieve effective signal coverage. The 2×0.8mm gauge is suitable for areas close to the main line, and the 2×1.0mm gauge can be used for places slightly farther away, ensuring that each user can receive stable telephone signals.

The laying of telephone lines in rural areas is an important application field. Rural areas have diverse terrains, and some areas are inconvenient in transportation. The aerial laying method does not require large-scale ground excavation, which can reduce construction difficulty and cost. The PE insulation layer of this telephone drop wire has strong weather resistance, and can resist the influence of natural environments such as wind, sun, and rain in rural outdoors. Even in cold winters or hot summers, it can maintain stable performance.

This drop wire can be laid aerial on both sides of roads and between factories in the park to provide stable communication lines for enterprises. Its twin parallel structure is not easily affected by electromagnetic interference generated by machinery and equipment in the industrial park, ensuring that the call quality is not affected. The 2×1.0mm gauge can be used to connect enterprises far apart in the park, and the 2×0.8mm gauge is suitable for short-distance communication connections inside the park.

This telephone drop wire can also play an important role in outdoor communication wiring of residential communities. It can be laid aerial from the communication room of the community to each residential building, and then introduced from the residential building to the households. Its twin parallel structure is easy to install, will not have a great impact on the landscape of the community, and the PE insulation layer has strong aging resistance, which can be used in outdoor environments for a long time, providing stable guarantee for residents' daily telephone communication.

(3) Material and Style

Material

Conductor: High-purity oxygen-free copper is used as the Conductor Material, with a purity of more than 99.95%. Oxygen-free copper has excellent electrical conductivity and high conductivity, which can minimize signal loss during transmission and ensure clear and stable telephone signals. At the same time, oxygen-free copper has good ductility and Flexibility. During aerial installation, even after a certain degree of bending and stretching, it is not easy to break, and can adapt to complex outdoor installation environments. In addition, oxygen-free copper has strong corrosion resistance, is not easy to be oxidized and corroded in outdoor environments, and prolongs the service life of the conductor.

Insulation layer: High-quality polyethylene (PE) material is selected as the insulation layer. PE material has excellent weather resistance, can resist long-term ultraviolet radiation without aging, and maintains good performance in the temperature range of -40℃ to 60℃. Whether in severe cold or extreme heat, it can provide reliable protection for the conductor. It has good chemical stability, can resist the erosion of rain, dew, dust in the air, acids, alkalis and other substances, and ensures long-term stable insulation performance. Moreover, PE material has good electrical insulation performance, which can effectively isolate signal interference between the two core wires and ensure the purity of signal transmission.

Style

The telephone drop wire adopts a twin parallel design. The two core wires are arranged parallel to each other, and the outside is wrapped with a layer of PE insulation layer to form a whole. This structure keeps the distance between the two core wires fixed, reducing mutual interference during signal transmission. The overall appearance is flat with a thin thickness, which is convenient for fixing during aerial installation, and can be easily wrapped around the fixing devices of electric poles or laid along walls.

In terms of color, the insulation layer is usually black. Black not only has good dirt resistance, but also absorbs less sunlight heat, reducing the impact of excessive temperature on the performance of the insulation layer. In outdoor environments, black is also relatively hidden, which can coordinate with the surrounding environment and not be too abrupt. In addition, the surface of the wire body is smooth and flat, with no obvious protrusions or depressions, which reduces the friction during installation and facilitates construction operations.

(4) Production Process

The production process of 18/2, 22/2 gauge one pair 2×0.8mm, 2×1.0mm PE insulation copper outdoor aerial twin parallel telephone drop wire is rigorous and standardized to ensure that the product quality meets relevant standards.

First is the manufacturing of the conductor. High-purity oxygen-free copper rods are drawn into Copper Wires with the required diameter through a wire drawing machine. For the 2×0.8mm gauge, the diameter of the copper wire is about 0.9mm; for the 2×1.0mm gauge, the diameter of the copper wire is about 1.1mm. During the wire drawing process, the wire drawing speed and die precision are strictly controlled to ensure that the diameter of the copper wire is uniform and the surface is smooth without burrs, so as to ensure its electrical conductivity and mechanical properties. After wire drawing, the copper wire is annealed to eliminate internal stress in the copper wire and enhance its flexibility.

Next is the extrusion molding of the insulation layer. An extruder is used to heat PE particles to a molten state, and the molten PE material is evenly wrapped around the outside of the two parallel copper wires through a special die to form a twin parallel insulation structure. During the extrusion process, the extrusion temperature (usually 150℃-180℃), speed and pressure are precisely controlled 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. The thickness of the insulation layer varies according to the gauge. The thickness of the insulation layer for the 2×0.8mm gauge is about 0.5mm, and that for the 2×1.0mm gauge is about 0.6mm to provide sufficient insulation and protection.

After extrusion molding, the telephone drop wire is cooled, usually by water cooling, to quickly solidify and shape the PE insulation layer to ensure the dimensional stability of the wire body. After cooling, traction and take-up are also required to wind the wire body on the reel according to a certain length. During the take-up process, the traction speed and tension are controlled to avoid excessive stretching or twisting of the wire body.

Finally, there is the quality inspection link. A series of tests are carried out on the finished products, including the detection of conductor diameter, insulation layer thickness, insulation resistance, tensile strength and other items, to ensure that each batch of products meets the quality standards. Only products that pass the inspection can enter the subsequent packaging and sales links.

II. General Product Information
