AI Technical Summary

Technical Problem

Existing cables are prone to flattening, twisting, and deformation when buried underground, which can lead to damage to the insulation layer and failure of the waterproof layer. Furthermore, single-layer waterproof designs are susceptible to water leakage, affecting the cable's lifespan and safety.

Method used

The cable adopts a multi-layer buffer anti-deformation pre-embedded pressure-resistant cable structure, including a corrugated ring plate, a double waterproof layer, a rigid support layer, an elastic buffer layer, and an insulation layer, forming a three-dimensional pressure-resistant skeleton and a double water barrier. The corrugated ring plate and buffer layer disperse stress, avoid stress concentration, and enhance the cable's anti-deformation ability and structural stability.

Benefits of technology

It effectively blocks groundwater seepage, prevents the cable core from getting damp, improves the structural reliability and service life of the cable in heavy-duty pre-buried scenarios, and maintains the stability and protection effect of the cable under complex working conditions.

Abstract

This invention discloses a multi-layer buffered anti-deformation pre-embedded pressure-resistant cable, belonging to the field of cables. This multi-layer buffered anti-deformation pre-embedded pressure-resistant cable includes a corrugated ring plate located inside a protective sleeve, with the outer side of the corrugated ring plate contacting the inner wall of the protective sleeve. A first waterproof layer is fixedly connected inside the corrugated ring plate. A support layer is fixedly connected to the inner wall of the first waterproof layer. A second waterproof layer is fixedly connected to the inner wall of the support layer. A buffer layer is fixedly connected to the inner wall of the second waterproof layer. An insulation layer is fixedly connected to the inner wall of the buffer layer. The inner wall of the insulation layer contacts the outer side of the core. The intermediate component adopts a multi-layer composite structure consisting of a corrugated ring plate, double waterproof layers, a rigid support layer, an elastic buffer layer, and an insulation layer. The outer corrugated ring plate achieves initial pressure relief and deformation buffering, while the intermediate support layer forms a three-dimensional pressure-resistant skeleton to resist radial compression, soil settlement, and lateral shear force, ensuring the overall roundness and non-deformation of the cable.
