Abstract
Provided is a 12-20kV waterproof anti-corrosion flexible cable which comprises a plurality of wire cores and an insulating sheath wrapping the wire cores. The wire cores comprise at least three conductors, reinforcing cores, and insulating sleeves wrapping the conductors and the reinforcing cores. The conductor and the reinforcing cores are interwoven and twisted together. A ratio of the number of the reinforcing cores to the number of the conductors is 1 to 2. The insulating sleeve is formed by an inner insulating sleeve and an outer insulating sleeve. The inner insulating sleeve is produced by high-density polymerized ethylene. The outer insulating sleeve is produced by expanded polymerized ethylene. Waterproof adhesive is extruded on the wire cores and the insulating sheath. The insulating sheath is produced by Polyether ether ketone. The 12-20kV waterproof anti-corrosion flexible cable has a greatly-prolonged service life and is effectively prevented from wearing and fracturing and stabilized in transmission quality.
Description
Technical field
The utility model relates to a kind of silicon rubber insulation flexible electric power cable, relates 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, by many insulated wire cores twisted synthesizing cables, forms cable core; 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 utility model, for the deficiencies in the prior art, provides a kind of long service life, core steady quality, effectively wear prevention fracture, the corrosion-resistant flexible cable of the corrosion resistant 12 ~ 20kV waterproof of waterproof.
The utility model is for 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 consists 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 utility model is the improvement to the structure of 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 have greatly been 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.
The beneficial effects of the utility model: the utility model has improved the useful life of cable greatly, effectively prevent effective wear prevention fracture, and transmission quality is stable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
