Embodiment Construction

[0013] Such as figure 1 and figure 2 As shown, a high-voltage lightning protection cable according to the present invention includes a plastic inner support core 1, a conductor stranded layer 2, a cross-linked polyethylene insulating layer 3 and a weather-resistant polyethylene sheath layer 4, wherein the conductor is stranded Layer 2 is coated on the plastic inner support core 1, the cross-linked polyethylene insulating layer 3 is coated on the surface of the conductor stranded layer 2, and the weather-resistant polyethylene sheath layer 4 is coated on the cross-linked polyethylene insulating layer Layer 3 surface.

[0014] Among them, the plastic inner support core 1 greatly reduces the effective section of the cable conductor, which eliminates the skin effect when the lightning protection cable conductor passes through the instantaneous huge lightning strike current; at the same time, it also reduces the unit weight of the cable to a large extent, making it It is more co...

Abstract

The invention relates to a high-voltage lightning protection cable, which is characterized by comprising a plastic internal stay core, an electric conductor twisting layer, a crosslinking polyethylene insulating layer and a weatherproof polyethylene sheathing layer, wherein the electric conductor twisting layer is coated on the plastic internal stay core, the crosslinking polyethylene insulating layer is coated on the surface of the electric conductor twisting layer, and the weatherproof polyethylene sheathing layer is coated on the surface of the crosslinking polyethylene insulating layer. The high-voltage lightning protection cable has the characteristics of scientific structure design, good lightning protection and shielding effects, and excellent weatherproof and anti-corrosive properties, thus the high-voltage lightning protection cable can be widely applied to various harsh environment conditions.

Description

technical field [0001] The invention relates to a cable structure. Background technique [0002] At present, most common cables are composed of conductive core, insulating layer and sheath layer. When this type of cable is used in field or open-air erection applications, accidents caused by lightning strikes often occur. Especially with the vigorous development of high-rise buildings, people pay more and more attention to the application of lightning protection facilities, and the application of lightning protection facilities, the demand for cables capable of lightning protection is getting higher and higher, and lightning protection cables have emerged as the times require. The supporting application of lightning protection cables and lightning protection facilities can give high-rise buildings good lightning protection functions, so that buildings can be kept intact from lightning strikes, thereby protecting people's lives and property. Contents of the invention [00...
