Description
Technical field
The technology of the heat insulation flexible cable of the utility model flame-retardant; refer in particular to low smoke halogen-free fire retardant fire resistant flexible cable; be applicable to cable needs more soft; higher to environmental protection requirement; particular/special requirement is had to environment; as there being the occasion of particular/special requirement to fire-resistant, heat-resisting, heatproof, fire-retardant etc., have good value for applications.
Background technology
At present, the pressure common crosslinked cable that market is sold is generally adopt crosslinked polyetylene insulated pvc sheath, although the electric pressure used is identical, its thermal stability is general, the feature of environmental protection is poor, needs that are fire-resistant, environmental protection can not be ensured, though on its skin is coated simply flame retardant coating, also because of control not thorough and damaged, thus cause damage, impact power supply.
In order to solve the problems such as the poor-performings such as existing pressure common cable fire, heat-resisting, heatproof, fire-retardant, environmental protection, the scope of application is limited, the present inventor improves for the performance of pressure common specially, then has this case to produce.
Utility model content
Main purpose of the present utility model is the heat insulation flexible cable of flame-retardant providing a kind of flame-retardant performance good.
Secondary objective of the present utility model is to provide a kind of harmless resistant environmental low-smoke halogen-free flame refractory heat-insulating flexible cable.
In order to reach above-mentioned purpose, solution of the present utility model is:
The heat insulation flexible cable of a kind of flame-retardant, is made up of conductor wire core, mica tape, insulating barrier, inserts, sheath, Halogen band and restrictive coating; Wrapped mica tape on conductor wire core; Coated insulation layer on mica tape; Coated insulating barrier forms cable core together with the conductor wire core strand of mica tape, the gap-fill inserts in the middle of cable core, and the peripheral coated sheath of cable core, sheath is Ceramic silicon rubber material, wrapped Halogen band on sheath, coated restrictive coating on Halogen band.
The thickness of described Ceramic silicon rubber material sheath is 2.0mm.
Described conductor wire core is copper conductor.
Described insulating barrier is XLPE cross-linking polyethylene materials.
Described restrictive coating is halogen-free and low-smoke flame-retardant polyolefin material.
Described Halogen band is double-deck Halogen band.
Described inserts is mineral wool rope.
After adopting said structure, the utility model adds certain thickness Ceramic silicon rubber material sheath outside cable core, duricrust tubular fire heat insulation structural can be changed rapidly into when meeting fire or high temperature, in fire fighting environment, still can maintain certain hour not damaged, effectively stop that flame or high temperature are to the damage of primary insulation.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Label declaration
Conductor wire core 1, mica tape 2, insulating barrier 3, inserts 4, sheath 5, Halogen band 6, restrictive coating 7.
Embodiment
As shown in Figure 1, the heat insulation flexible cable of a kind of flame-retardant that the utility model discloses, is made up of conductor wire core 1, mica tape 2, insulating barrier 3, inserts 4, sheath 5, Halogen band 6 and restrictive coating 7.Conductor wire core 1 can adopt copper conductor, wrapped mica tape 2 on conductor wire core 1.Coated insulation layer 3 on mica tape 2, insulating barrier 3 can adopt XLPE cross-linking polyethylene materials.Cable core is formed together with coated insulating barrier 3 twists with the conductor wire core 1 of mica tape 2.Gap-fill inserts 4 in the middle of cable core, inserts 4 can adopt mineral wool rope, and the peripheral coated sheath 5 of cable core, sheath 5 is Ceramic silicon rubber material, and preferred thickness is 2.0mm.Wrapped double-deck Halogen band 6 on sheath 5.Coated restrictive coating 7 on Halogen band 6, restrictive coating 7 can adopt halogen-free and low-smoke flame-retardant polyolefin material.
Fire-resisting flexible cable described in the utility model, it is the upgrading of pressure common flexible cable product, remain the due electric and mechanical performance of pressure common flexible cable product, simultaneously, key technology of the present utility model is: outside cable core, add certain thickness Ceramic silicon rubber material sheath 5, for soft type thermo-setting elastomer, do not running in flame ablation situation, it is more soft jacket material, the excellent bending performance of fireproof construction when can guarantee normal, duricrust tubular fire heat insulation structural can be changed rapidly into when meeting fire or high temperature, certain hour still can be maintained not damaged in fire fighting environment, effective stop flame or high temperature are to the damage of primary insulation.
The inserts of whole cable and restrictive coating can all be adopted the manufacture of low smoke and zero halogen material by the utility model, cable is burnt in a fire also can not produce thick smoke, LSZH, environmental protection, harmless, be conducive to people's escape, therefore can be widely used in some densely populated and emphasis fireproof places.
