Description
Technical field
What the utility model related to cable designs and produces field.
Background technology
The capacity of installed generator of current China and annual energy output Jun Ju second place of the world, China region is wide, electric power resources in the West enriches, transferring electricity from the west to the east needs to build remote, large span, jumbo new transmission line, and due to major part in current China overhead transmission line be all use conventional steel core aluminum stranded wire (ACSR), a lot of old circuit needs capacity-increasing transformation.
But can line flashover be caused due to thunder and lightning, power frequency continued flow still can blow cable; Secondly, steel reinforced aluminium conductor softening temperature is low, poor heat resistance; Again, 10kV steel reinforced aluminium conductor product structure falls behind, and causes the outside diameter of cable to increase, and material consumption is too much, has been unworthy again applying.Along with reform deepens continuously, the demand of all trades and professions to electric energy is more and more higher, provide that one has high strength simultaneously, light aerial insulated cable become in the urgent need to.
Utility model content
The utility model object is for above problem, provides a kind of portable high-strength aerial insulated cable.
The utility model comprises cable core, flame-proof polyvinyl chloride insulating barrier is wrapped up outside described cable core, described cable core comprises four strands of aluminum-zirconium alloy conductors, arranges saddle-shape filled core at the center of four strands of aluminum-zirconium alloy conductors, and described saddle-shape filled core is that halogen free nanometer compounded rubber extrusion molding forms; Described four strands of aluminum-zirconium alloy conductors and the mutual twisted synthesizing cable of saddle-shape filled core.
The utility model has following beneficial effect: (1) conductor adopts aluminum-zirconium alloy to have the advantages such as stretching resistance is large, lightweight, sag is little, long service life, aluminum-zirconium alloy thermal endurance is high simultaneously, wire operating temperature can be improved, increase power transmission capacity of pow, reduce capital expenditure cost.(2) insulation adopts environment-friendlyflame-retardant flame-retardant polyvinyl chloride to have excellent heat resistance, resistance to ag(e)ing and anti-flammability and ensures the fail safe that circuit runs.(3) prefabricated saddle-shape filled core adopts halogen free nanometer compounded rubber to have the advantages such as corrosion resistant, light, tension.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises cable core, wraps up flame-proof polyvinyl chloride insulating barrier 1 outside cable core, and cable core comprises four strands of aluminum-zirconium alloy conductors 2, arrange saddle-shape filled core 3 at the center of four strands of aluminum-zirconium alloy conductors 2, saddle-shape filled core 3 forms for halogen free nanometer compounded rubber extrusion molding; Four strands of aluminum-zirconium alloy conductors 2 and saddle-shape filled core 3 twisted synthesizing cable mutually.
