Background technology
According to GB/T12706-2008 standard, power cable has fixedly to lay and move and lays two kinds, power cable 1 class or the hard conductor compacting circle of 2 classes or the sector conductor structures of adopting for fixedly laying at present more, and all adopt the 5 class flexible conductor constructions of cable for the power cable of mobile occasion, because the filament diameter of flexible conductor is thinner, in stranded process, easily there is the shortcoming of fracture of wire and loose distortion, the general circle that adopts is pressed flexible conductor structure, this adds more packing material to make cable rounding when needing cable cabling, so just make whole cable external diameter increase, cable material is increased, increase the manufacturing cost of cable.And it is fire-retardant and shield effectiveness is bad, is not suitable for especially and has the communication equipment of shielding requirements to connect.Power cable use occasion difference, the material to cable and the requirement of structure are also different.At present be generally polyvinyl chloride or ethylene-propylene rubber for insulation and the sheath material of flexible conductor power cable, and traditional polyvinyl chloride flexibility is bad, ethylene-propylene rubber needs sulfuration, equipment and production process complexity, and material cost is high.
Utility model content
The utility model object is to provide a kind of sector conductor proof copper-wire braided shielded flexible cable, by adopting fan-shaped compact conductor structure, proof copper-wire braided shielding construction, save cable cost, provide that a kind of shielding is good, the cable of flexibility and good flame resistance, solve the problems referred to above that exist in background technology.
The technical solution of the utility model is: a kind of sector conductor proof copper-wire braided shielded flexible cable, comprise fan-shaped copper conductor, fan-shaped copper conductor is provided with the elastic body insulated layer of fire-retardant butyronitrile PVC outward successively, fire-retardant PP gasket for packing, tape for cables, metal screen layer and fire-retardant butyronitrile PVC elastomer outer jacket, the elastic body insulated layer of described fire-retardant butyronitrile PVC, that fan-shaped copper conductor extrudes fire-retardant butyronitrile PVC elastomer outward, form fan-shaped insulated wire cores, several fan-shaped insulated wire cores are stranded forms into cable core, become the outer wrapped tape for cables of cable core, fire-retardant PP gasket for packing is filled with at tape for cables and becomes between cable core, the outer wrapped metal screen layer of tape for cables, metal screen layer extrudes fire-retardant butyronitrile PVC elastomer outer jacket outward.
Described fan-shaped copper conductor is that some strands of bundle strand adpressings form the fan-shaped copper wire bundle stranded conductor that twists again.
The quantity of described fan-shaped insulated wire cores is three or four.
Described metal screen layer is proof copper-wire braided shielding construction, count >=80%.
The beneficial effects of the utility model are: adopt fan-shaped compact conductor structure, reduced the outside diameter of cable, saved cable cost; Adopt proof copper-wire braided structure, make cable there is good shielding properties, can be connected with communication equipment; Adopt flame-proof PVC butyronitrile elastomeric material, flexibility and good flame resistance, cold resistance is good, and the cost of material is low.
