Multichannel anti-pressing electric cable

Abstract

The invention discloses a multi-channel compression-resistant electric wire and cable, which belongs to the technical field of electric wire and cable, and comprises a body, which includes a cable core support for fixing a cable core group and a sheath layer arranged on the periphery of the cable core support; the sheath layer Including wear-resistant outer sheath, buffer braid, shielding braid and waterproof inner sheath arranged in sequence from outside to inside; cable core group includes peripheral thick wire group and central thin wire group; Distributed partitions; the partitions are connected to form a peripheral channel for placing the peripheral thick wire group; the center of the cable core support is provided with a central channel for placing the central thin wire group; the peripheral channel and the central channel are connected to form a cable arrangement path; Evenly distributed buffer extrusion balls are arranged in the buffer braiding layer. The invention has the characteristics of strong wear resistance, good compression resistance, long service life, etc.; and through the cable core bracket, the wires of the cable are divided into thick and fine, and different channels are set, so that the wires are arranged in an orderly manner.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a multi-channel pressure-resistant wire and cable. Background technique [0002] Wires and cables are used to transmit electric (magnetic) energy, information and wire products that realize the conversion of electromagnetic energy. In a broad sense, wires and cables are also referred to as cables for short. In a narrow sense, cables refer to insulated cables, which can be defined as: a collection composed of the following parts ; One or more insulated wire cores, and their respective possible covering layers, total protective layer and outer sheath, and the cable may also have additional uninsulated conductors. Wire products used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion. [0003] Wires and cables are called the "arteries" and "nerves" of the national economy. They are indispensable basic equipment for transmitting...

AI Technical Summary

Problems solved by technology

But from an objective point of view, compared with the wire and cable industry in Europe and the United States, my country is still in a big but not strong situation, and there is still a big gap with foreign famous wire and cable brands.

Sometimes the cable catches fire due to a short circuit of the cable itself, or a voltage overload, or a fire on the outside of the cable.

After the cable catches fire, its burning speed is very fast. If the insulating layer wrapped in the outer layer of the cable is made of clinker, it itself is flammable, especially in the case of electrification, it can cause a serious fire in a short time, causing serious damage to the people. and the country caused huge losses
