Abstract
The invention provides a power station cable, and relates to a cable, in particular to a control cable for a power station. The power station cable aims at providing the power station cable with the advantages that the defect of poor fire-resistant performance of the existing cable is overcome, the cost is low, and the manufacturing is easy. The fire-resistant performance, the environment-friendly performance and the anti-jamming performance of the cable are improved. The power station cable adopts the technical scheme that the power station cable comprises a conductor, a polyester tape, an insulation layer, a flame retardant layer, a weaving layer and an outer sheath, wherein the polyester tape covers the periphery of the conductor, the insulation layer covers the outer layer of the polyester tape, the flame retardant layer covers the outer layer of the insulation layer, the weaving layer covers the outer layer of the flame retardant layer, and the outer sheath covers the outer layer of the weaving layer. The power station cable is applied to the power station.
Description
Technical field
The present invention relates to a kind of cable, particularly relate to a kind of power station control cables.
Background technology
At present, in cable industry, fireproof control cable generally adopts the wrapped mode adding insulation of fire-resistant isinglass belt, but Mica tape class fire-resisting cable is in wrapped or bending process, mica sheet easily comes off, not by spray, vibratory test, and mica tape kind is more again now, and quality is uneven, less stable, is difficult to the fire resistant quality ensureing cable.Secondly, the insulation that common fireproof control cable uses and sheath material mostly all contain halogen or do not reach the environmental requirement of European Union ROHS instruction.Moreover the wrapped production of small bore fireproof control cable is restricted, and fire resistance quality more cannot be protected.And the poor anti jamming capability of such cable.
In addition, although the normal power supply that still can maintain a period of time after catching fire, there is price, complex process, problem that difficulty of construction is large in existing mineral insulated cable.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of low cost, the station cable that easily makes that can overcome the fire-resistant poor defect of existing cable, improves the fire resistance of cable, environmental-protecting performance and interference free performance.
For solving the problems of the technologies described above, the technical solution adopted in the present invention: a kind of station cable, comprise conductor, polyester belt, insulating barrier, flame-retardant layer, braid and oversheath, described polyester belt is wrapped in conductor periphery, described insulating barrier is wrapped in the skin of polyester belt, described flame-retardant layer is wrapped in the skin of insulating barrier, and described braid is wrapped in the skin of flame-retardant layer, and described oversheath is wrapped in the skin of braid.
Described oversheath is made up of thermal insulation layer, packed layer and fireprotection layer.
Described conductor is the good copper conductor of fire resistance.
Described insulating barrier is LSOH anti-flaming second third insulating barrier.
Described flame-retardant layer is high-performance refractory fiber.
Described braid is that zinc-coated wire braiding forms.
Described oversheath is that thermoset polymer resin is bonded.
Described thermal insulation layer is mineral wool, silicate or both mixtures, and described packed layer is rock wool layer, is filled with plastic hollow microballon in described fireprotection layer.
Described high-performance refractory fiber adopts glass fiber, and tightens with glass fabric band.
Compared to the prior art the present invention, has following beneficial effect.
One, insulating barrier adopts LSOH anti-flaming second the third, plays good insulation effect.
Two, filled glass fiber silk in flame-retardant layer, and tighten with glass fabric band, and in fireprotection layer, be filled with plastic hollow microballon, there is the present invention there is well high temperature resistant and fire resistance.
Three, braid is that zinc-coated wire braiding forms, and has good anti-interference.
Four, because oversheath is that thermoset polymer resin is bonded, use working temperature higher, substantially increase the ampacity of cable, make cable in same ampacity situation, the cross-section of cable can reduce further.
Five, the thermal insulation layer arranging oversheath is mineral wool, silicate or both mixtures, makes cable possess good effect of heat insulation.
Six, the present invention has fire-resistant, environmental protection, the interference free performance of excellent electrical insulation capability, interference free performance and excellence, and processing technology is simple simultaneously, and transport is laid convenient, and cost performance is higher.
