Ceramic fireproof fire-resistant silicon rubber wire and cable

Abstract

The invention relates to a ceramic fireproof fire-resistant silicon rubber wire and cable. The wire and cable comprise a plurality of conductors, each conductor is wrapped by a ceramic silicon rubber insulating layer in an extruding mode to form a wire core, multiple wire cores are wrapped by a wrapping tape layer to form a cable core, padding is arranged in the cable core, and a ceramic silicon rubber outer sheath is arranged outside the cable core. The ceramic fireproof fire-resistant silicon rubber wire and cable have characteristics batter than those of a common rubber cable and a flame retardant rubber cable and form a hard shell after being ablated by high-temperature flames to protect a burned article from being damaged, and the hard shell formed after ablation protects the wire and cable, so that unblocked electric power and communication are ensured, and precious time are won for personnel evacuation and rescue under the fire disaster condition.

Description

technical field [0001] The invention relates to a wire and cable, in particular to a ceramic fireproof and refractory silicon rubber wire and cable. Background technique [0002] In recent years, after fires in several large public entertainment venues, chemical industry, coal mines, and commercial buildings in China caused tragic loss of people's lives and property, people have a deeper understanding of fire protection and fire safety. With the rapid growth of urban population, the continuous increase of high-rise buildings, hotels, large supermarkets, hospitals, stations, and airports, the construction of subways and tunnel traffic, and the increase of large-scale public sports, entertainment venues, and public transportation facilities, fire prevention and fire prevention The importance of safety is highlighted. How to ensure the smooth flow of power and communication within a certain period of time in the event of a fire, maximize the precious rescue time, and reduce ca...

Problems solved by technology

Magnesia mineral fire-resistant insulated cables need special production and processing equipment, and the equipment for producing magnesium oxide mineral fire-resistant insulated cables not only needs to be imported, but also very expensive, and the capital investment is too large; in addition, the outer sheath of magnesium oxide mineral fire-resistant insulated cables is full The cost of copper is relatively high, and its practical application is limited to a certain extent; coupled with the special requirements of copper-sheathed magnesium oxide mineral fire-resistant insulated cables in the process of production, processing, transportation, line laying, installation and use, such as The production and processing of magnesium oxide mineral fire-resistant insulated cables cannot be as convenient as polymer materials. It is difficult to lay and install, and the cost of raw materials is high. It is difficult to popularize and use it on a large scale, especially difficult to promote it in civil buildings, etc.

The fire-resistant cable wrapped with mica tape needs to be wound in multiple layers in the production process. Due to the limitation of process conditions, it is easy to cause defects at the lap joints. It is difficult to ensure the safety and smoothness of communication and power in case of fire
