Abstract
The utility model discloses a kind of flame retardant cable, comprise conductor, polyester belt, insulating barrier, flame-retardant layer, braid and oversheath, described oversheath is wrapped in the skin of braid, described braid is wrapped in the skin of flame-retardant layer, described flame-retardant layer is wrapped in the skin of insulating barrier, described insulating barrier is wrapped in the skin of polyester belt, is enclosed with conductor in described polyester belt, and described oversheath is provided with coating.Anti-interference cable of the present utility model filled glass fiber dimension cloth band in the gap of cable conductor is tightened, and have well high temperature resistant and fire resistance, aluminium foil layer just has good anti-interference.
Description
Technical field
The utility model relates to a kind of cable, particularly relates to a kind of control cables with anti-interference fire resistance.
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.
Utility model content
The purpose of this utility model is to provide a kind of flame retardant cable, to overcome the technological deficiency of existing fire-resisting cable, improves the fire resistance of cable, environmental-protecting performance and interference free performance.
Flame retardant cable of the present utility model, comprise conductor, polyester belt, insulating barrier, flame-retardant layer, braid and oversheath, described oversheath is wrapped in the skin of braid, described braid is wrapped in the skin of flame-retardant layer, described flame-retardant layer is wrapped in the skin of insulating barrier, described insulating barrier is wrapped in the skin of polyester belt, is enclosed with conductor in described polyester belt, and described oversheath is provided with coating.
As preferably, described insulating barrier is rock wool layer.
As preferably, described flame-retardant layer is low-smoke non-halogen flame-retardant band.
As preferably, described conductor is graphite.
As preferably, described coating is aluminium oxide.
Flame retardant cable of the present utility model is filled glass fiber silk in the gap of cable conductor, and tightens with glass fabric band, and have well high temperature resistant and fire resistance, aluminium foil layer just has good anti-interference.
Due to refractory ceramics fire-resistant silicon rubber use working temperature higher, can reach 180 DEG C and more than, substantially increase the ampacity of cable, cable is in same ampacity situation, and cross section can reduce further.
Flame retardant cable of the present utility model has fire-resistant, environmental protection, the interference free performance of excellent electrical insulation capability, interference free performance and excellence, and processing technology is simple, and transport is laid conveniently, and cost performance is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model flame retardant cable.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
With reference to Fig. 1, this embodiment is by the following technical solutions: flame retardant cable, comprise conductor 1, polyester belt 2, insulating barrier 3, flame-retardant layer 4, braid 5 and oversheath 6, described oversheath 6 is wrapped in the skin of braid 5, described braid 5 is wrapped in the skin of flame-retardant layer 4, and described flame-retardant layer 4 is wrapped in the skin of insulating barrier 3, and described insulating barrier 3 is wrapped in the skin of polyester belt 2, be enclosed with conductor 1 in described polyester belt 2, described oversheath 6 is provided with coating.
As preferably, described insulating barrier 3 is rock wool layer.
As preferably, described flame-retardant layer is low-smoke non-halogen flame-retardant band.
As preferably, described conductor 1 is graphite.
As preferably, described coating is aluminium oxide.
Originally filled glass fiber silk in the gap being embodied in cable conductor, and tighten with glass fabric band, there is well high temperature resistant and fire resistance, aluminium foil layer just has good anti-interference, due to refractory ceramics fire-resistant silicon rubber use working temperature higher, can reach 180 DEG C and more than, substantially increase the ampacity of cable, cable is in same ampacity situation, and cross section can reduce further
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
