Description
Technical field
The present invention relates to field of cable technology, particularly relate to a kind of waterproof insulation power cable.
Background technology
Power cable is defeated, the requisite electric product of distribution, be also power cable is applied the most generally, the most extensively,
The one having the call.Along with progress and the expanding economy of society, the mankind are more and more higher to the degree of dependence of electric energy, to electricity
The demand of energy is increasing.China the most actively develops supertension, special ehv power transmission circuit, along with EHV transmission
The development of technology, proposes the highest requirement to the important component part-power cable of electrical network, it is necessary to withstand height
Pressure, the test of supertension.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of waterproof insulation power cable.
The present invention is achieved by the following technical solutions:
A kind of waterproof insulation power cable, includes the petal insulating strength pipe being spliced by four arc skeletons, insulation
Being provided with cross insulation board inside reinforced pipe, the lumen segmentation of insulating strength pipe is become four little cavitys by cross insulation board,
Cross insulation board surface smear has inorganic heat-absorbing material sprayed coating, is not provided with core four loculus internal body portion, described
Core includes conductor and is coated on the high-density polyethylene resin insulating barrier outside conductor and plastic-aluminum combined thin film screen successively
Cover layer, between each core and insulating strength pipe, be provided with carbon fiber glass fibre recombination line and high temperature resistant elastic buffer rod,
The outside of insulating strength pipe is coated with the shape nylon heat-insulation layer identical with insulating strength pipe, metal knitted screen layer and half successively
Hard flame-proof polyvinyl chloride oversheath, is coated with bituminous coating in the outside of semihard flame-retardant polrvinyl chloride oversheath.
Described high temperature resistant elastic buffer rod is ceramic macromolecule composite fire silicon rubber bar.
Described insulating strength pipe is nylon tube.
It is provided with several mesh on the surface of described insulating strength pipe.
