Self-radiating self-bearing anti-pressure coaxial fireproof cable

Abstract

The invention discloses a self-radiating self-bearing anti-pressure coaxial fireproof cable comprising an inner conductor, an insulation layer, an outer conductor, a buffer layer and an outer sheath arranged inside-out; the inner conductor comprises a bearing core arranged in the center and a plurality of inner conductor conductive single wires twisted with the bearing core and surrounding the bearing core; the outer conductor is formed by parallelly winding a plurality of outer conductor conductive single wires; a metal anti-pressure pipe is arranged between the buffer layer and the outer sheath; the outer sheath is also provided with single wire protruding ridges, wherein the height of the ridge is not smaller than 0.1mm, and the width is not smaller than 5mm; the outer sheath is in a tooth form; a fireproof coating is coated in the tooth form so as to form a plurality of fireproof layers arranged at equal intervals; a plurality of protruding grooves extrude outside the outer sheath,and filled with a heat absorption cotton, thus sucking and diffusing the heat energy from the cable, and preventing the hidden troubles caused by cable self-combustion.

Description

technical field

[0001] The invention relates to the field of wires and cables, in particular to a self-radiating, self-supporting, compression-resistant coaxial fireproof cable. Background technique

[0002] Today's world has entered the information age, and information has become a strategic resource for economic development and a unique factor of production. A modern information transmission system and a complete information service system established by combining long-distance communication networks, computers, video and other multimedia terminals, It has become an important symbol of the economic development of a country or region. Coaxial cable is an important variety in information transmission. It is mainly used as an antenna feeder for radio transmitting or receiving equipment and as an internal connection or interconnection line for various communications and electronic equipment. The coaxial cable is composed of inner conductor layer, insulating layer, outer condu...
