Abstract
The utility model discloses a high temperature resistance fireproof control cable comprising four conductors, the four conductors are respectively wrapped by a fireproof mica layer and a fluoroplastic insulating layer in sequence to form insulation cores, the insulation cores are parallelly and longitudinally arranged to form a cable core, a taped covering, a copper wire shielding layer and an inner jacket are arranged outside the cable core in sequence, the inner jacket and the copper wire shielding layer form one body by plastic extrusion moulding, a thickness of the inner jacket is bigger than or equal to 2.5mm, an armor layer formed by winding steel band is arranged outside the inner jacket, a flame retardation fluoroplastic sheath layer is arranged outside the armor layer by plastic extrusion moulding, a fireproof coating is arranged outside the flame retardation fluoroplastic sheath layer, and a thickness of the fireproof coating is bigger than or equal to 0.6mm. The high temperature resistance fireproof control cable has novel structure design, the copper wire shielding layer and the inner jacket are combined in one body, so whole structure of the cable is more compact, simultaneously the fireproof coating is arranged outside the sheath layer of the cable, and fireproof performance of the cable is improved.
Description
Technical field:
The utility model relates to control cables, relates in particular to a kind of fire resistant control cables.
Background technology:
In public places such as hospital, airport, subway, railway, commercial buildings, and places such as military applications, iron and steel, metallurgy, chemical industry, boats and ships, rolling stock, fire-resisting cable is a kind of application trend, also is the important topic of from now on field of cables research.
Has higher cable for fire resistance, directly burning is lower to stand flame, fault within a certain period of time is not short-circuited, English is female when fire occurs, be conducive to reduce the loss, it is larger to be applicable to various fire hazards, security against fire importance high field electrical equipment and control system in connect line and use.
Previous control cables is loosely organized, and in high temperature resistant, fire protection requirement highland environment, result of use is relatively relatively poor, so that greatly shorten the useful life of cable, the cable transmission of information can not get ensureing simultaneously.
The utility model content:
In order to solve the prior art defective, the purpose of this utility model provides a kind of fire resistant control cables, and structural design is novel, has improved resistance to elevated temperatures and the fire protecting performance of cable, and structural compactness improves simultaneously.
The technical solution of the utility model is as follows:
The fire resistant control cables, comprise four conductors, it is characterized in that: described four conductors are surrounded with the fireproof mica layer outward respectively successively, the fluoroplastic insulation layer consists of insulated wire cores, the parallel vertical formation cable core of putting of insulated wire cores, cable core is provided with lapping layer outward successively, shielding layer of copper wires, inner cushion layer, described inner cushion layer forms one by extrusion moulding and shielding layer of copper wires, the thickness of inner cushion layer is not less than 2.5mm, inner cushion layer is provided with the armour of the wrapped formation of steel band outward, the outer extrusion moulding of armour has fire-retardant fluoroplastics restrictive coating, described fire-retardant fluoroplastics restrictive coating is provided with refractory coating outward, and the thickness of refractory coating is not less than 0.6mm.
Described fire resistant control cables is characterized in that: the wrapped Duplication of the steel band of described armour is not less than 45%.
Described fire resistant control cables is characterized in that: described inner cushion layer material can adopt silicon rubber or polyethylene.
The utility model has the advantages that:
The utility model structural design is novel, and by shielding layer of copper wires and inner covering are combined into one, so that the overall structure of cable is compacter, the restrictive coating of the cable outside is provided with refractory coating simultaneously, can improve better fire resistance.
