Abstract

The utility model provides an environment-protective fire-proof shield flexible cable for moving, which has high-low temperature resistant property, fine insulation performance, high breakdown voltage, large thermal-insulation index, strong bending performance, small bending-resistant radius, strong moving and anti-interference performance and nontoxic property. The cable comprises an insulating wire core and a cable core stranded by reinforcing ribs to form the cable. A wearing-resistant thin wrapping layer made of non-absorbent materials, a ceramic fire-proof silicon rubber lining layer, a tin plated copper braid shielding layer and a ceramic fire-proof silicon rubber outer protecting layer are sequentially disposed on the cable core from inside to outside. The insulating wire core is formed by extruding a ceramic fire-proof silicon rubber insulating layer on stranded annealed copper wire conductors.

Description

Environment-friendly type moves uses the fire-proof shield flexible cable

Technical field

The utility model relates to a kind of cable, is specifically related to a kind of environment-friendly type and moves and use the fire-proof shield flexible cable.

Background technology

Sharp increase along with urban population, skyscraper, hotel, large supermarket, hospital, station, airport constantly increase, subway, tunnel and large-scale place of public amusement, public transit facility are also in rapid increase, and the importance of security against fire shows especially out; Particularly how under fire condition, ensureing the unimpeded of electric power and communication line within a certain period of time, try to gain time precious to one to greatest extent, reduce personnel's the injures and deaths and the loss of lives and properties, is the problems that people constantly explore.

At present, the fire-resisting cable of most magnesium oxide fire-proof insulation cable that adopts of fireproof electric wire and cable both domestic and external and mica tape winding.This two have certain defective: need the Special Equipment of import price costliness as the cable of producing this structure of magnesium oxide fire-proof insulation, fund input is too big; In addition, the outer jacket of this kind cable is full copper, so cost is also higher; Add fireproof electric wire and cable and move specific (special) requirements in the processes such as laying installation and use at production, processing, transportation, circuit, be difficult to large-scale popularizing and use, particularly in civil buildings; And adopt the fire-resisting cable that mica tape twines to need multi-lay winding in process of production, because the restriction of process conditions, often cause seam defective to occur under the regular mobile condition, mica tape embrittlement after ablating, come off easily, poor, the fire-resistant effect of travelling performance is bad, thereby is difficult to ensure that communication, power circuit are safe and smooth under the situation of fire.

Summary of the invention

The utility model is in order to overcome the deficiencies in the prior art, provides a kind of high-low temperature resistant, good insulation preformance, puncture voltage height, heat-resistance index is big, bending property is strong, anti-bending radius is little, move and strong anti-interference performance, nontoxic environment-friendly type move and use the fire-proof shield flexible cable.

The purpose of this utility model is achieved in that a kind of environment-friendly type moves and uses the fire-proof shield flexible cable, this cable is provided with the cable core of insulated wire cores and the stranded stranding of reinforcement, be provided with the non-hygroscopic material lapping layer of wear-resisting thin type on the cable core from inside to outside successively, pottery chemoprevention fire silicon rubber inner covering, the tinned copper wire woven shield, pottery chemoprevention fire silicon rubber outer jacket, the non-hygroscopic material lapping layer of wear-resisting thin type is wrapped on cable core, on the non-hygroscopic material lapping layer of wear-resisting thin type, extrude ceramic chemoprevention fire silicon rubber inner covering, at ceramic chemoprevention fire silicon rubber inner covering outer surface braiding tinned copper wire woven shield, on the tinned copper wire woven shield, extrude ceramic chemoprevention fire silicon rubber outer jacket.

Described insulated wire cores constitutes by extruding ceramic chemoprevention fire silicone rubber insulation layer on the tough copper wire conductor of multiply.

The utility model improves existing fireproof cable from new material, new technology, adopt the new ceramics fire-resistant silicon rubber, possesses silicone rubber for cable at normal temperatures, nonpoisonous and tasteless, environmental protection, high-low temperature resistant, anti-ozone aging, weather-resistant, superior characteristic such as electrical insulation capability is good, travelling performance is strong, good bending property, anti-bending radius are little; Under 500 ℃ of high temperature even the flame ablation more than 700 ℃, the potteryization fire-resistant silicon rubber forms hard pottery armour body protective layer, reaches the fireproof effect thereby play oxygen barrier, has guaranteed electric power, the unimpeded purpose of communication under fire condition.

Beneficial effect: the utility model is rational in infrastructure simple, manufacture easily, employing is by extruding insulated wire cores and the reinforcement stranding that ceramic chemoprevention fire silicone rubber insulation layer constitutes on the tough copper wire conductor of multiply, the non-hygroscopic material lapping layer of wear-resisting thin type is set on the cable core, pottery chemoprevention fire silicon rubber inner covering, the tinned copper wire woven shield, pottery chemoprevention fire silicon rubber outer jacket, make electricity high temperature resistant, good insulation preformance, the puncture voltage height, heat-resistance index is big, bending property is strong, anti-bending radius is little, travelling performance is strong, anti-mechanical external force damage, wear-resisting wiping, the oil resistant dirt, anti-electromagnetic interference performance is superior, high flame retardant fire prevention fire screen oxygen asepsis environment-protecting.
