CN203503337U - High-temperature-resistant insulating flexible cable - Google Patents

Abstract

The utility model discloses a high-temperature-resistant insulating flexible cable. A main conductor, control conductors and power conductors are all formed by multiple galvanized and tin-plated copper wires which are twisted in bundles. Both the outer side of the main conductor and the outer side of each control conductor are sequentially covered by a fluoroplastic insulating layer and a high-intensity polyester yarn braided layer. The outer side of each power conductor is covered by a fluoroplastic insulating layer. A through hole is disposed in the center of a cruciform rubber skeleton. The main conductor is disposed in the through hole. Each of the four corners of the cruciform rubber skeleton is provided with a control conductor and is wrapped by a multiple-layer mineral tape material overlap clad layer to form a wire core. The outer side of the wire cores is provided with multiple power conductors and then is sequentially wrapped by an aluminum magnesium alloy filament braided layer, a talcum powder and magnesium carbonate mixture filling layer, a glass fiber fireproof layer and an aramid fiber layer. The cable is characterized by light weight, easy bending, high intensity and high temperature resistance, is convenient for installation and maintenance, and has good flexibility and long service life.

Description

A kind of high-temperature insulation flexible cable

Technical field

The utility model relates to cable technology field, relates in particular to a kind of high-temperature insulation flexible cable.

Background technology
