Special high temperature-resistant electrical cable and its production method

Abstract

The utility model discloses a special refractory electrical power cable, which comprises a plurality of conductors, an insulation layer, a first fiber glass braided layer, an obturator, a copper wire braided layer, a second fiber glass braided layer and a serving. The utility model has the advantages that the safe operation of the electrical power signal can be guaranteed because the electrical power cable is made of high temperature resistant material; the access end of the electrical power cable can be peeled conveniently as the electrical power cable is switched into other circuits, because the second fiber glass braid layer is made of fiberglass material; the good circularity, hand feeling and desired appearance of the electrical power cable are ensured because the obturator is filled in the gap among a plurality of conductors;, the copper wire mesh braided layer can shield the whole electrical power cable from outside disturbances; meanwhile, the utility model discloses a manufacture method for the refractory power cable.

Description

technical field [0001] The invention relates to a power cable, and more particularly to a special high temperature resistant power cable and a manufacturing method thereof. Background technique [0002] At present, wires and cables have been widely used in industrial production, transportation, construction engineering and facilities, modern agriculture and scientific research, military equipment or military facilities, space, ocean detection, and have reached a ubiquitous state. With the step-by-step development of social and economic activities from depth to breadth, the varieties of wire and cable are constantly updated and improved, and the production volume continues to increase. For example, the construction of high-intelligence buildings requires computer network cables for hierarchical networking of hundreds or thousands of electronic computers; the establishment of urban public cable TV networks, the universal deposit and withdrawal of all banks in the city and even...

AI Technical Summary

Problems solved by technology

[0006] However, there are certain defects in the current general-purpose cables

For example, with the continuous improvement of economic and social life, the power consumption has also increased significantly, so the input voltage to the cable has also increased step by step. Therefore, the temperature of the cable rises rapidly, causing the cable to be unable to withstand high temperatures and continue to heat up. burnt, thus greatly affecting the realization of the entire cable circuit

In addition, when the cable is connected to other lines, the cable access end needs to be peeled off, and the material covering the outer layer of the conductor in the existing cable is extremely difficult to peel off

In addition, the conductor is generally round, and there are inevitably gaps between the conductors of the multi-core cable. When these conductors are extruded (wrapped) with insulating layers and sheaths, the conductors are extruded to form a wavy appearance. Greatly affects the feel and aesthetics of the cable
