Embodiment Construction

[0022] The structure of the power cable provided by the invention is as figure 1 As shown, there are 3 wire cores and 1 connecting wire core 2 inside the cable. The outside of the wire is covered with an insulating layer 4; the outside of the wire core 1 and the wire core 2 is surrounded by a shielding layer 6, and the space between the shielding layer 6 and the wire core 1 and the wire core 2 is a filling layer 5, A rubber sheath 7 is covered on the outside of the shielding layer 6 .

[0023] The tinned copper wire used in the present invention has extremely good solderability, and as time changes, the solderability remains good and can be stored for a long time. In addition, the surface of the tinned copper wire is smooth, bright and moist, and it has excellent performance Stable and reliable, ensuring the advantages of high quality and high yield.

[0024] The shielding layer on the cable structure in the present invention is a measure to improve the distribution of the e...

Abstract

The invention relates to a cross-linking insulated tin-plated copper wire power cable resistant to a high temperature and under 35kV, and belongs to the technical field of power equipment. The cross-linking insulated tin-plated copper wire power cable comprises wire cores and a power connection core, wherein the three wire cores and the power connection core are arranged in the cable and are both internally structured with tin-plated copper wires, insulation layers wrap the tin-plated copper wires, a shielding layer encircles the wire cores and the power connection core, a filling layer is arranged among the shielding layer, the wire cores and the power connection core, and a rubber sheath wraps the shielding layer. The cable disclosed by the invention is applied to high-voltage power engineering and has the characteristics of low line loss of the wire cores, high conductivity and small sag; and compared with a conventional wire, the wire has the characteristics of remarkable low relaxation degree and has the advantages of high allowable working temperature, large carrying capacity, light weight and corrosion resistance.

Description

technical field [0001] The invention relates to a high temperature resistant cross-linked insulated tinned copper wire power cable below 35kV, which belongs to the technical field of electric equipment. Background technique [0002] Wires and cables are used to transmit and distribute electric energy in the power system; they are used for connection between various electrical equipment; advantages: 1. The cable has good mechanical strength, bending performance, anti-corrosion performance and long service life, and has no impact on the surrounding environment. Small; 2. Stable power transmission performance, safe and reliable, large capacity; 3. Convenient laying - direct burial, pipe penetration, trench, tunnel, shaft (and no drop requirements) are all available, but it cannot be used in long-term immersion in water. [0003] The working temperature of heat-resistant and high-temperature cables has its strict regulations. According to the International Electrotechnical Comm...
