Abstract

The invention relates to the field of communication technology, and specifically discloses an environment-friendly super fire-resistant communication power supply flame-retardant flexible cable, which includes a plurality of power lines and wrapping layers, isolation layers, interlocking armor layers and outer sheathing layers arranged outside the power lines in sequence. The sheath layer; the power cord includes a conductor and a synthetic mica tape wrapping layer and an insulating layer that are sequentially coated on the outside of the conductor; the gap between the power cord and the wrapping layer is filled by a glass fiber rope; the interlocking The armor layer is made of aluminum alloy tape chain armor; the insulating layer is made of low-smoke halogen-free polyolefin; the conductor is soft round copper wire; the wrapping layer is wrapped with glass fiber tape; the isolation layer is made of ceramic Chemical refractory silicone rubber; the outer sheath layer is extruded with a low-smoke, halogen-free, flame-retardant polyolefin sheath. The invention has the advantages of good softness, long fire resistance time, safety and environmental protection.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an environment-friendly flame-retardant flexible cable for super fire-resistant communication power supply. Background technique [0002] With the acceleration of my country's economic construction, people pay more and more attention to the safety requirements of the living environment, and the subsequent fire safety is becoming more and more important and urgent. Power systems in important places such as large-scale CBDs, subways, large-scale exhibition venues, stadiums, and important national defense bases put forward higher requirements for the safety performance of cables under fire conditions. [0003] The existing flame-retardant and fire-resistant cables for communication power supplies on the market are generally ordinary copper-core fire-resistant cables, and the quality of the cables is uneven. , When a fire occurs, the outer sheath will burn and produce toxic s...
