Abstract
Disclosed is a silicone rubber insulation power cable suitable for voltage of 6 to 15 kv. The cable comprises at least three power wire cores, an oversheath wrapping the power wire cores. Each power wire core comprises a tin copper conductor and a silicone rubber insulation layer wrapping the tin copper conductor. The surface of the silicone rubber insulation layer is covered by an epoxy resin layer. The power wire cores are disposed around the center of the circle at an interval of 3 to 5 mm. The gaps among the power wire cores and the gap between the power wire cores and the oversheath are filled with chloroprene rubber. Glass fibers are uniformly disposed inside the chloroprene rubber. Thus, the cable makes great improvements in bending-resistant performance, prolongs service lifetime and improves transmission performance.
Description
Technical field
The utility model arranges a kind of silicon rubber insulation flexible electric power cable, relates in particular to a kind of rated voltage 6 to 15kV silicon
Rubber-covered flexible electric power cable.
Background technology
China Patent Publication No. is that CN 203102986 U disclose a kind of rated voltage 6 to 15kV silicon rubber insulation flexible electric power cable, comprise that three by some tinned copper wires or the stranded copper conductor forming of bare copper wire, described copper conductor outer surface is coated with the first semiconductive silastic-layer, one silicone rubber insulation layer is coated on described the first semiconductive silastic-layer outer surface, thereby one second semiconductive silastic-layer is coated on described silicone rubber insulation layer outer surface and forms power core, three stranded formation cable cores of this power core, one bed course is coated on this cable core outer surface, this bed course outer surface is coated with restrictive coating, in this restrictive coating, between inner restrictive coating and external sheath layer, be provided with braiding reinforced layer.Its technical scheme be mainly to the improvement of restrictive coating, by setting up braiding reinforced layer, effectively prevent electromagnetic interference, improve the stability of cable transmission signal, although this technical scheme possesses good signal transmission and anti-interference, but because its power core is mutual stranded setting, and do not possess insulation and extrude packing material, the bending drag of core mutual stranded in long-term use procedure is larger, cannot be suitable for the complicated environment of pulling strings, easily cause distortion of the cable, and extrude packing material owing to lacking insulation, between power core, wearing and tearing are comparatively serious mutually, greatly shorten useful life, have much room for improvement.
Summary of the invention
The utility model, for the deficiencies in the prior art, provides a kind of effective raising cable extended, the 6 ~ 15kv silicon rubber insulating power cable that makes its bending coefficient strengthen and greatly increase the service life.
The utility model is for solving the problems of the technologies described above, improve following technical scheme: a kind of 6 ~ 15kv silicon rubber insulating power cable, comprise power core, be wrapped in the oversheath on power core, described power core is provided with at least 3, every power core is made up of tin copper conductor and the silicone rubber insulation layer that is wrapped in tin copper conductor surface, it is characterized in that silicone rubber insulation layer surface-coated has epoxy resin layer, every power core all arranges around interval, the center of circle 3 ~ 5mm, its mutual gap and with oversheath gap in be all filled with neoprene, in described neoprene, be evenly equipped with glass fiber.
Key problem in technology of the present utility model is, power core interval is arranged, the neoprene that makes it mutually have certain gap and pass through to fill flexible insulation, make it effectively prevent each other friction, greatly improve bending coefficient, can adapt to more environment, moreover the application has epoxy resin layer in silicone rubber insulation layer surface-coated, by the good anti-interference of epoxy resin, greatly improve the transmission performance of cable, and be evenly equipped with glass fiber in the utility model neoprene, by this kind of setting, effectively prevent the breakage problem of neoprene due to aging generation, improve the useful life of cable.
As of the present utility model preferred, oversheath is enough become by insulate braid and ethylene-propylene rubber layer.
The beneficial effects of the utility model: the utility model has improved the bending resistance of cable greatly, and greatly extended useful life and improved transmission performance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of 6 ~ 15kv silicon rubber insulating power cable, comprise power core 001, be wrapped in the oversheath 002 on power core 001, described power core 001 is provided with 3, every power core 001 is made up of tin copper conductor 011 and the silicone rubber insulation layer 012 that is wrapped in tin copper conductor 011 surface, silicone rubber insulation layer 012 surface-coated has epoxy resin layer 013, every power core 001 all arranges around interval, the center of circle 3 ~ 5mm, its mutual gap and with oversheath 002 gap in be all filled with neoprene 003, in described neoprene 003, be evenly equipped with glass fiber 004.Described oversheath 002 is reached into by insulation braid 021 and ethylene-propylene rubber layer 022.
Claims (2)
1. 6 ~ 15kv silicon rubber insulating power cable, comprise power core, be wrapped in the oversheath on power core, described power core is provided with at least 3, every power core is made up of tin copper conductor and the silicone rubber insulation layer that is wrapped in tin copper conductor surface, it is characterized in that silicone rubber insulation layer surface-coated has epoxy resin layer, every power core all arranges around interval, the center of circle 3 ~ 5mm, its mutual gap and with oversheath gap in be all filled with neoprene, in described neoprene, be evenly equipped with glass fiber.
