Abstract
The utility model discloses a kind of fire resistant flexible power cable, include conductor, described conductor presses moulding by single round copper or many copper, in the outside of described conductor, be coated with successively double-deck mica tape flame retardant coating and crosslinked polyetylene insulated layer, to after many conductor bundle strands, in outside, be coated with successively glass fibre lapping layer, ceramic silicon rubber separator, low-smoke halogen-free polyolefin inner covering, galvanized steel strip armour and low-smoke halogen-free polyolefin oversheath, in described glass fibre lapping layer inner side, be provided with glass cord packed layer.The maximum operating temperature of the utility model cable conductor is no more than 90 ℃, and having is being difficult to fight has the ability that stops or delay propagation of flame, applied range, and excellent insulation performance, good heat conduction effect, can reduce heat accumulation.
Description
Technical field
The utility model relates to cable technology field, relates in particular to a kind of fire resistant flexible power cable.
Background technology
Along with the quickening of scientific and technological progress and modernization construction paces and the heavy losses that fire causes in recent years, make the importance of fire-fighting, fire safety more show especially out, people are always in the situation that constantly exploring how at fire for this reason, ensure in a long time the unimpeded of electric power and communication, try to gain time precious to one to greatest extent, flue gas toxity can not cause secondary injury to people's life, reduces personnel's poison gas death and the loss of lives and properties.Therefore the produce market demand of fireproof cable increases day by day; but because the cable using on present market is all insulation and the sheath that common material is made substantially; cable does not have well fire-retardant and fire protecting performance; run into burst fire condition under cable can not play protection device security normally move; can not start fire-extinguishing apparatus by normal power supply, the safe escape that affects personnel causes damage.Thereby be necessary to develop the fire resistant flexible power cable that a kind of structural material has fire-retardant fireproof environmental-protecting performance.
Utility model content
The utility model object is exactly in order to make up the defect of prior art, and a kind of fire resistant flexible power cable is provided.
The utility model is achieved through the following technical solutions:
A kind of fire resistant flexible power cable, include conductor, described conductor presses moulding by single round copper or many copper, in the outside of described conductor, be coated with successively double-deck mica tape flame retardant coating and crosslinked polyetylene insulated layer, to after many conductor bundle strands, in outside, be coated with successively glass fibre lapping layer, ceramic silicon rubber separator, low-smoke halogen-free polyolefin inner covering, galvanized steel strip armour and low-smoke halogen-free polyolefin oversheath, in described glass fibre lapping layer inner side, be provided with glass cord packed layer.
Conductor is that single round copper or many copper press moulding twisted wire, adopts such conductor material structure, has stable structure, the wide scope of application, excellent conductivity etc.;
Insulation adopts fabricated structure, first at conductive surface, is wound around double-deck fire-resistant isinglass belt, then extrudes the good crosslinked polyethylene of electric property and make insulating barrier, forms fireproof the first line of defence;
Space between electric wire adopts glass cord to fill, and increases the tensile strength of cable, guarantees that cable has good roundness; Serviceability temperature wide ranges can be used for a long time within the scope of-70~200 ℃; After 650~3000 ℃ of temperature or flame condition burning, form rapidly hard housing, play the fire-resistant effect of fire insulation; Excellent insulation performance, good heat conduction effect, can reduce heat accumulation.Electric wire outside adds high-intensity heat-proof corrosion resistant glass fiber package band and carries out wrapped;
The separator of this cable is ceramic silicon rubber, there is special flexibility, fire line, heat insulation back-fire relief, at the temperature of-70~200 ℃, the elasticity with ordinary silicon rubber, flexibility, electrical property and mechanical performance, can round-the-clock normal use, bending radius is little, can equally with common rubber cable above coil, lay, under more than 350 ℃ nonflame high temperature and more than 600 ℃ flame ablations, form hard ceramic duricrust protective layer, also there is good insulating properties simultaneously, can play well isolated flame, the effect of fire-proof insulation, thereby guaranteed under fire condition, electric power, communication unimpeded.
Inner covering adopts and extrudes flame-retardant low-smoke halogen-free polyolefine material, environment-protecting asepsis evil;
Armour adopts galvanized steel strip, guarantees that cable can resist the injury of external mechanical force, can be buried or ground lay use.
Outer jacket adopts high flame retardant rank halogen-free polyolefin plastics, burning can be limited in subrange, does not produce and spreads, and the low cigarette of environmental protection, does not produce pernicious gas, keeps other various device, avoids resulting in greater loss.
The utility model has the advantages that: the maximum operating temperature of the utility model cable conductor is no more than 90 ℃, having is being difficult to fight has the ability that stops or delay propagation of flame, applied range, and excellent insulation performance, good heat conduction effect, can reduce heat accumulation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of fire resistant flexible power cable, include conductor 1, described conductor 1 presses moulding by single round copper or many copper, in the outside of described conductor 1, be coated with successively double-deck mica tape flame retardant coating 2 and crosslinked polyetylene insulated layer 3, by being coated with successively glass fibre lapping layer 4, ceramic silicon rubber separator 5, low-smoke halogen-free polyolefin inner covering 6, galvanized steel strip armour 7 and low-smoke halogen-free polyolefin oversheath 8 in outside after many conductors 1 bundle strand, in described glass fibre lapping layer 4 inner sides, be provided with glass cord packed layer 9.
