Abstract
The utility model discloses a high fire -retardant middling pressure aluminum alloy cable, including at least a set of electric unit, in the filling layer is arranged in to electric unit, the filling layer outward in proper order the cladding have band layer, fire -retardant inner liner, metal armor layer and a fire -retardant oversheath layer, electric unit includes aluminum alloy conductor, aluminum alloy conductor outward in proper order the cladding have conductor shield, insulating layer, insulation screen and iron shielded layer. The utility model has the advantages that: 1 )Have good mechanical properties and creep resistance properties, aluminum alloy conductor's creep resistance properties reaches the level of copper. 2 )Through setting up band layer, fire -retardant inner liner, filling layer and fire -retardant oversheath layer, the fire behaviour of cable has been improved greatly.
Description
Technical field
A kind of a kind of the utility model discloses aluminium alloy cable, in particular it relates to jewelling alloy cable in high fire-retardance.
Background technology
The grade of medium-pressure power cable is 6kv～35kv, and traditional medium-pressure power cable is divided into copper core and fine aluminium core electric power electricity
Cable, copper core cable price is high, and fine aluminium core power cable price is low, but fine aluminium core power cable due to the mechanical performance of its own and
Creep-resistant property poor it is difficult to obtain large-area applications.Accordingly, it would be desirable to a kind of novel power cable is substituting traditional medium voltage electricity
Cable.
Utility model content
The purpose of this utility model is for solving above-mentioned deficiency, provides and a kind of has good mechanical performance and creep resistance
Jewelling alloy cable in the high fire-retardance of energy.
The technical solution adopted in the utility model is:
Jewelling alloy cable in a kind of high fire-retardance, it includes least one set electric unit, and described electric unit is placed in packed layer,
It is coated with belting layer, fire-retardant inner liner, metal armor layers and fire-retardant external sheath layer, described electric unit bag successively outside described packed layer
Include aluminium alloy conductor, outside described aluminium alloy conductor, be coated with conductor shield, insulating barrier, insulation screen and metallic shield successively
Layer.
Further, described electric unit has three groups.
Further, described metal armor layers by galvanized steel strip or non magnetic armoring tape by the way of Double-layer gap is wrapped
Make.
The utility model has the advantages that:
1) there is good mechanical performance and creep-resistant property, the creep-resistant property of aluminium alloy conductor reaches the level of copper.
2) pass through to arrange belting layer, fire-retardant inner liner, packed layer and fire-retardant external sheath layer, substantially increase the fire-retardant of cable
Performance.

Combustion external sheath layer 10, metal armor layers 9 are made up by the way of Double-layer gap is wrapped of galvanized steel strip or non magnetic armoring tape.
Aluminium alloy conductor 1 of the present utility model is 8000 series alloys conductors, has good mechanical performance and resists compacted
Become performance, its creep-resistant property can reach the level consistent with copper.
Fire-retardant inner liner 8 of the present utility model and fire-retardant external sheath layer 10 are high flame retardant polyvinyl chloride material, have excellent
Elegant fire resistance, can greatly improve the anti-fire ability of cable, improve safety in the case of catching fire for the cable.
Belting layer 7 of the present utility model is high fire-retardance band or glass fibre belt, has good fire resistance.
Packed layer 6 of the present utility model is polypropylene flame redardant gasket for packing or flame-proof polyvinyl chloride packing, has good
Fire resistance.
Metal armor layers 9 of the present utility model are galvanized steel strip or non magnetic armoring tape, using Double-layer gap lapping structure
Form, has good isolation and not flame-retarding power energy.
Although above-mentioned preferred embodiment is made that detailed description to this utility model, not limited with above-described embodiment
Determine this utility model.Those skilled in the art is it should be recognized that without departing from the technology given by technical solutions of the utility model
In the case of feature and scope, increase that technical characteristic is made, with this area some same contents replacement, this reality all should be belonged to
With new protection domain.
