CN102810351A - Special-grade fire-resistant control cable for fire safety - Google Patents

Abstract

The invention relates to a special-grade fire-resistant control cable for fire safety. The special-grade fire-resistant control cable comprises a conductor, an insulating layer, an inner protecting layer and an outer protecting layer, wherein the outside of the conductor is extruded and coated with ceramic silicone rubber to form the insulating layer; a copper strip inner shield layer, a drainage wire and a high-resistant band taped inner covering are sequentially arranged outside the insulating layer to form a wire core; a plurality of wire cores are cabled and then are wrapped to form a taped outer covering; and a copper wire braiding outer shielding layer, a composite silicon rubber inner protecting layer, a steel tape armoring layer and a composite silicon rubber outer protection layer are sequentially arranged outside the taped outer covering. The special-grade fire-resistant control cable disclosed by the invention has the advantages of reasonable structure, advanced process, favorable firefighting, fireproof signal transmission and anti-jamming properties, favorable flame retardant and fire resisting performances and the like. The special-grade fire-resistant control cable can be widely applied to public fire protection, electrical appliances and instrument devices in places having very high requirement on fire safety and control cables of fire alarm signals and various automatic device signals.

Description

Superfine fireproof control cable is used in a kind of security against fire

Technical field

The present invention relates to a kind of cable technology field, superfine fireproof control cable is used in particularly a kind of security against fire.

Background technology

In the last few years; Country several families large-scale place of public amusement, chemical industry, colliery, people's life that the commercial building fire causes and the heaviness loss of property, people have had more deep understanding to fire-fighting, fire safety, along with the population sharp increase; The construction of the continuous increase on skyscraper, hotel, large supermarket, station, airport, subway, tunnel traffic; The fire incident in building, Jiangzhou road, Shanghai on the 15th November in 2010 particularly, the importance of fire-fighting fire-proof safety further shows especially out, how under the situation of fire; Ensure within a certain period of time electric power with communicate by letter unimpeded; Win the quality time to greatest extent, reduce personnel's the injures and deaths and the loss of property, this is that people are always in the problem of constantly controlling rope.

Summary of the invention

The present invention provides the security against fire of a kind of rational in infrastructure, flame-retardant, the transmission of fire prevention signal to use superfine fireproof control cable in order to overcome the above problems.

Technical scheme of the present invention is: comprise conductor, insulating barrier, sheath and outer jacket; Described conductor extrudes potteryization silicon rubber outward and constitutes insulating barrier; Insulating barrier sets gradually lapping layer formation core in copper strips internal shield, drainage thread and the high stopband outward; The outer lapping layer of wrapped formation behind some core strandings, said outer lapping layer sets gradually copper wire braiding outer shielding layer, composite silicone rubber sheath, steel-tape armouring layer, composite silicone rubber outer jacket outward from inside to outside.

The present invention is rational in infrastructure, technology is advanced, possess good fire-fighting, the fire prevention signal transmits, noiseproof feature; Have advantages such as good flame retardancy and fire resistance; The electric equipment and the metering device that can be widely used in the very high place of public fire protection, fire safety requirement, the control cable of fire alarm and various automatics signals.
