Problems solved by technology

However, the large and small earthquakes in recent years have seriously damaged the transmission lines, which not only caused incalculable economic losses to the society, but also affected the development of the entire society and the national economy, and seriously affected the earthquake relief and post-earthquake reconstruction work.
At present, there are a few anti-seismic cables, but there are disadvantages such as complex structure, high production cost, and poor actual effect.

Embodiment Construction

[0007] to combine figure 1 The present invention is further described in detail.

[0008] Such as figure 1 As shown, a shockproof cable includes two cable cores 1, an insulating layer 2 arranged on the outside of the conductive cable core, a middle armor layer 3 and an outermost sheath 4, and the outer part of the insulating layer 2 is a fire-resistant The wrapping layer 5 is made of different materials, and the wrapping layer 5 is covered with an anti-shock protection layer 6, and the armor layer 3 is made of two layers of inner and outer armors with opposite stranding directions. The anti-shock protective layer is polyurethane elastomer material.

Abstract

An earthquake-proof cable comprises the components of at least one cable core, an insulating layer which is arranged outside each cable core, a middle armoring layer and an outmost sheath. A winding layer which is made of a refractory material is arranged outside the insulating layer. An earthquake-proof protecting layer is arranged outside the winding layer. The armoring layer is composed of an inner armoring layer and an outer armoring layer, wherein the intertwisting direction of the inner armoring layer is opposite from that of the outer armoring layer.

Description

technical field [0001] The invention relates to the field of power cables, in particular to the technical field of shockproof and shockproof cables. Background technique [0002] There are various radiation methods of wires and cables, mainly overhead, through pipes, direct burial, and bridges. With the continuous progress of the society, people pay more attention to the urban environment, greening the urban environment and improving the quality of life. Therefore, people turn the "Skynet" overhead line into an underground pipeline transmission line to beautify the environment. However, the large and small earthquakes in recent years have seriously damaged the transmission lines, which not only caused incalculable economic losses to the society, but also affected the development of the entire society and the national economy, and seriously affected the earthquake relief and post-earthquake reconstruction work. At present, there are a few anti-seismic cables, but there are d...
