Compression and heat resistant practical wire cable

Abstract

The invention discloses a compression and heat resistant practical wire cable, which comprises a fireproof lapped covering, a plurality of main wire cores and a reinforcing core tube are arranged in the fireproof lapped covering, the reinforcing core tube is arranged among the plurality of main wire cores, and a plurality of compression-resistant support frames are arranged among the plurality ofmain wire cores at equal intervals. The reinforcing core tube penetrates through the plurality of compression-resistant support frames to make contact with the inner wall of the fireproof lapped covering, the interior of the fireproof lapped covering is filled with heat-insulating and flame-retardant particles, and the exterior of the fireproof lapped covering is coated with a compression-resistant and flame-retardant layer. The plurality of compression-resistant support frames are arranged on the main wire cores and the reinforcing core tube, so that a good compression-resistant protection effect can be achieved on the wire cable, when the cable is extruded, a polyurethane elastomer material can achieve a protection effect on the main wire cores and the reinforcing core tube, and the problems of short circuit and the like caused by damage of an insulating layer can be avoided; and when the cable is subjected to external impact, an elastic connecting piece can play a role in buffering,so that the stress of the cable can be dispersed, and the flame-retardant outer sheath is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a pressure-resistant and heat-resistant practical wire and cable. Background technique [0002] Wire and cable are used to transmit electric energy, information and wire products to realize electromagnetic energy conversion. In the broad sense, wires and cables are also referred to as cables for short. In the narrow sense, cables refer to insulated cables, which can be defined as: a collection composed of the following parts; one or more insulated cores, and their respective possible coatings. Protective layer and outer sheath, the cable may also have additional uninsulated conductors. [0003] The vast majority of wire and cable products are products with the same cross-sectional shape and long strips, which are determined by the characteristics used to form circuits or coils in systems or equipment. Therefore, to study and analyze the structural composition of cable ...

AI Technical Summary

Problems solved by technology

[0004] Existing wires and cables have insufficient compression resistance. When used in construction sites or production workshops, because the cables are often trampled and squeezed, the inner cores or insulation layers of the cables are prone to damage after long-term use, resulting in the application of If there is a power outage in the place, it may even cause property damage and personal injury accidents due to short circuit or leakage

And the existing wire and cable products do not have good heat and fire resistance
