Description
Technical field
The utility model relates to field of cables, relates in particular to the fire-resistant compound inslation high flame retardant of a kind of environment protection double-shielded low pressure flexible cable.
Background technology
Along with the quickening of Chinese society economic construction paces and the raising of people's environmental consciousness, halogen-free, low-smoke, flame is widely used in important department and public places such as skyscraper, subway, power plant, tunnels.When breaking out of fire, require cable line can keep within a certain period of time normal operation, simultaneously corrosivity during cable fire is lower, light transmission is good, rescue work is very helpful, can reduce casualties and property loss to a great extent, and the performance of common cable is not enough to tackle many factors, cause the emergency meeting accident.Under the ordering about of modernized society's fast development, common cable can not meet social needs, and having high performance cable will be employed widely, to guarantee in the situation that there is various special or burning issue, bring into play the effect of himself, loss is dropped to minimum.
Utility model content
The utility model cable is in order to address the above problem, and provides the environment-friendly type flexible conductor compound inslation double shield low pressure of a kind of 3kV and following fire safe type, explosion-proof type, anti-electromagnetic interference fire-resistant, low smoke, zero halogen, high flame-retardant cable.
For realizing above object, by the following technical solutions:
The fire-resistant compound inslation high flame retardant of a kind of environment protection double-shielded low pressure flexible cable, it is characterized in that, multiply soft copper wire harness closes the fire-resistant silicone band of rear wrapped individual layer, extrude again organosilane crosslinked polyethylene Halogen layer, outside organosilane crosslinked polyethylene Halogen layer, phase-splitting is dredged around copper wire and is formed core, after some core twisted synthesizing cables, wrapped 3 layers of fire-resisting ceramic silicone rubber band form fire-resistant layer of silica gel, fire-resistant layer of silica gel extrudes halogen-free flameproof sheath outward, between core and fire-resistant layer of silica gel, fill halogen-free glass fiber rope, outside halogen-free flameproof sheath, dredge around copper wire, extrude again halogen-free flameproof separator, separator external galvanized layer steel wire woven armored, finally extrude halogen-free flameproof outer jacket.
Conductor adopts the 5th kind of multiply bundle to close soft copper conductor, has improved the pliability of fire-resisting cable, is convenient to movement and the construction wiring of cable.
Composite insulation layer is by wrapped fire-resisting ceramic silicone rubber band and extrude Halogen insulating barrier and form.When fire occurs, in Halogen insulating barrier when burning, has the performance of fire-retardant, low toxicity, low cigarette; Fire-resisting ceramic silicone rubber band can Low fire ceramic shape when high-temp combustion, forms hard ceramic armouring, and protection circuit is unimpeded, and temperature is higher, and the ablation time is longer, and ceramic armouring is harder, and fire resistance can reach FV-0 level, and then point does not prolong combustion.
Double shield layer is on extruded insulation layer and sheath, to carry out respectively copper wire to dredge around shielding, can play anti-electromagnetic interference, uniform electric field, bear the effect of unsymmetrical current, safety ground.Compared with copper strip shielding, proof copper-wire braided shielding, shield effectiveness is better.
Fire-resistant silicon rubber layer is comprised of fire-resisting ceramic silicone rubber band.Fire-resisting ceramic silicone rubber band has good thermal insulation, and the inside after conductive coefficient 0.0033W/Mk, particularly ablation is cellular uniformly, has better fire resistance and thermal insulation; Flue gas toxity is highest level ZA1 level in CABLE MATERIALS, and the flue gas small white mouse after burning sucks after 30min, in 3 days, does not change.
Metal armouring layer adopts zinc-coated wire braiding armouring, when protection cable is not subject to extraneous mechanical damage, has also increased the pliability of cable.
Sheath, separator, outer jacket all adopt bittern-free flame-proof material, have guaranteed the hypotoxicity of cable, low cigarette, anti-flammability and anticorrosive property, have met the requirement of environment-friendly cable.
The utility model beneficial effect: cable has good flexibility, low toxic and environment-friendly, when meeting accident, cable line can keep normal operation within a certain period of time, and simultaneously corrosivity during cable fire is lower, and light transmission is good.
