Abstract
A 12 kV to 20 kV waterproof anti-corrosion soft cable comprises a plurality of strands of cable cores and an insulation sheath wrapping the cable cores, each cable core comprises at least three conductors, a reinforcing core and an insulation sleeve, the conductors and the reinforcing cores are wrapped by the insulation sleeves, the conductors and the reinforcing cores are interwoven and stranded integrally, the number ratio of the reinforcing cores to the conductors is 1:2, the insulation sleeves are composed of inner sheath bodies and outer sheath bodies, the inner sheath bodies are made of high-density polymerization ethylene, the outer sheath bodies are made of foaming polymerization ethylene, the cable cores and the insulation sheath are wrapped by water blocking glue in an extruded mode, and the insulation sheath is made of polyether-ether-ketone. The service life of the cable is greatly prolonged, the abrasion and breaking are effectively prevented, and the transmission quality is stable.
Description
Technical field
The present invention relates to a kind of silicon rubber insulation flexible electric power cable, relate in particular to a kind of rated voltage 12 to the corrosion-resistant flexible cable of 20kV waterproof.
Background technology
China Patent Publication No. is CN201477932U, and PEEK insulation high-temperature-resistant control cable is characterized in that extruding polyether-ether-ketone PEEK insulating barrier on single or many stranded tinned copper conductors and forms insulated wire cores, forms cable core by many insulated wire cores twisted synthesizing cables; In cable core, fill high temperature resistant packing material and form packed layer, and set gradually wrapped polytetrafluoroethylene belting layer, tinned copper wire woven shield and extrude silicone rubber jacket layer at the outer surface of packed layer.This technical scheme is by extruding polyether-ether-ketone PEEK insulating barrier, greatly improve the performance of its cable corrosion-and high-temp-resistant, but because it is not containing watertight composition, therefore in wet environment, useful life is poor for a long time, and its core is general tinned copper conductor, easy breaking strain in long-term bending use procedure, affects efficiency of transmission, haves much room for improvement.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of long service life is provided, core steady quality, effectively wear prevention fracture, the corrosion-resistant flexible cable of the corrosion resistant 12 ~ 20kv waterproof of waterproof.
The present invention is directed to the deficiencies in the prior art, provide following technical scheme: the corrosion-resistant flexible cable of a kind of 12 ~ 20kv waterproof, comprise some strand cores, be wrapped in the insulating sleeve outside core, it is characterized in that described core comprises at least three conductors, strengthening core and be wrapped in conductor, insulating case on strengthening core, described conductor and strengthening core stranded being integrated that interweave, between strengthening core and conductor, quantity is than being 1:2, described insulating case is made up of inside and outside two-layer sheath, inner sheath is high density polymerising ethylene, oversheath is foaming polymerising ethylene, described core and insulating sleeve are extruded with the glue that blocks water, described insulating sleeve is polyether-ether-ketone.In insulating sleeve, be lined with layer of glass layer.
Key problem in technology of the present invention is the improvement of the structure to core, by setting up strengthening core, and by strengthening core and conductor by certain more stranded, useful life and the efficiency of transmission of core are greatly improved, and in order to improve insulating properties and the anti-interference of core, insulating case is made as to inside and outside two-layer sheath.
Beneficial effect of the present invention: the present invention has improved the useful life of cable greatly, effectively prevents effective wear prevention fracture, and transmission quality is stable.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
