Abstract

A high temperature resistant fireproofing nanoscale flexible butt cable belongs to the technique field of cables. The butt cable includes several insulated wire cores and a cable core formed by twisting reinforcing rods, the cable core includes a wear-resistant thin type non-hygroscopic material winding cladding, a nanoscale ceramic fireproofing silastic liner, a tinning copper wire braided shielding layer and a nanoscale ceramic fireproofing silastic outer protective layer in sequence from inner outer. The butt cable has advantages of high temperature resistance, good insulation property, high breakdown voltage, great heat-proof index, strong bending performance and moving performance, superior rub resistance, oil stain resistance, superior electromagnetic interference resistance, environmental protection, fire prevention, high flame-proof and low cost.

Description

Fire resistant type nanoscale flexible cable

Technical field

The utility model belongs to the cable technology field, is specifically related to a kind of fire resistant type nanoscale 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.

The utility model content

The purpose of this utility model 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 and lower-cost fire resistant type nanoscale flexible cable.

The utility model comprises the cable core of some insulated wire cores and the stranded stranding of reinforcement, and cable core is provided with the non-hygroscopic material lapping layer of wear-resisting thin type, nanometer scale ceramics chemoprevention fire silicon rubber inner covering, tinned copper wire woven shield and nanometer scale ceramics chemoprevention fire silicon rubber outer jacket from inside to outside successively.

In order to reach better fire-proof high-temperature resistant effect, described insulated wire cores constitutes by extruding nanometer scale ceramics chemoprevention fire silicone rubber insulation layer on the tough copper wire conductor of multiply.

The utility model is rational in infrastructure simple; manufacture easily; employing is by extruding insulated wire cores and the reinforcement stranding that nanometer scale ceramics chemoprevention fire silicone rubber insulation layer constitutes on the tough copper wire conductor of multiply; cable core is provided with the non-hygroscopic material lapping layer of wear-resisting thin type outward; nanometer scale ceramics chemoprevention fire silicon rubber inner covering; the tinned copper wire woven shield; nanometer scale ceramics chemoprevention fire silicon rubber outer jacket; under 900 ℃ of high temperature even the flame ablation more than 1000 ℃; the nanometer scale ceramics fire-resistant silicon rubber forms hard pottery armour body protective layer; reach the fireproof effect thereby play oxygen barrier, under fire condition, guaranteed electric power; the purpose that communication is unimpeded.The utility model is high temperature resistant, good insulation preformance, 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, oil resistant dirt, anti-electromagnetic interference performance are superior, and prevent fires fire screen oxygen asepsis environment-protecting and cost of high flame retardant is lower.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model.

Wherein, the tough copper wire conductor of 1-multiply, 2-nanometer scale ceramics chemoprevention fire silicone rubber insulation layer, 3-reinforcement, the non-hygroscopic material lapping layer of the wear-resisting thin type of 4-, 5-nanometer scale ceramics chemoprevention fire silicon rubber inner covering, 6-tinned copper wire woven shield, 7-nanometer scale ceramics chemoprevention fire silicon rubber outer jacket.

Embodiment

As shown in Figure 1, constitute insulated wire cores by extruding nanometer scale ceramics chemoprevention fire silicone rubber insulation layer 2 on the tough copper wire conductor 1 of multiply.Be twisted into cable core with four eradication edge cores and five reinforcements 3, the non-hygroscopic material lapping layer 4 of wrapped successively from inside to outside wear-resisting thin type on the cable core, extrude nanometer scale ceramics chemoprevention fire silicon rubber inner covering 5, braiding tinned copper wire woven shield 6 extrudes nanometer scale ceramics chemoprevention fire silicon rubber outer jacket 7.

Claims

1. fire resistant type nanoscale flexible cable, it is characterized in that comprising the cable core of some insulated wire cores and the stranded stranding of reinforcement, outside described cable core, be provided with the non-hygroscopic material lapping layer of wear-resisting thin type, nanometer scale ceramics chemoprevention fire silicon rubber inner covering, tinned copper wire woven shield and nanometer scale ceramics chemoprevention fire silicon rubber outer jacket from inside to outside successively.
