Abstract
The utility model discloses a water-resistant cable comprising conductors, insulating layers, and an insulating sheath. A drying filler, a water-resistant filling rope, and a radial moisture-shielding layer are successively disposed between the insulating layers and the insulating sheath. Bag-packed drying agents are further embedded on the inner wall of the insulating sheath. The drying filler, the water-resistant filling rope, the radial moisture-shielding layer, and the bag-packed drying agents perform together so as to achieve multilayer water-resistant effects in radial and axial direction. And the use the drying filler and the bag-packed drying agents does not generate over high cost while enhancing water-resistant effects. Therefore, the water-resistant cable has low cost while achieving previous water-resistant effects.
Description
Technical field
The utility model relates to a kind of water repellent electric cable, belongs to the cables manufacturing technical field.
Background technology
Common cable itself does not possess water resistance characteristic, and be easy to infiltrate sheath or enter into cable inside from the breakage of sheath at the higher or long-term area of heavy rainfull of level of ground water moisture, and accidents caused.As far back as 20 century 70s, the water tree problem in the crosslinked polyetylene insulated electric wire has just caused the very big concern of international cable industry, and a lot of country has all done a large amount of research work.Mainly be to consider crosslinked polyethylene is carried out modification at first, adopt the method for adding voltage stabilizer and other additives to suppress the generation of water tree, though this measure has certain effect not remarkable, fail to tackle the problem at its root.Facts have proved afterwards prevents that secondary water from dividing immersion is the optimal path that solves water tree problem in the crosslinked polyethylene electric wire.The stop water of China's electric wire is to be referred from telecommunication cable mostly now, mainly be to prevent that to reach moisture from seeing through the purpose that sheath penetrates into insulating barrier by increasing the waterproof sheath, and not only to consider the moisture penetration radially of cable, to consider that also moisture immerses behind the cable longitudinal diffusion along cable, because if do not consider the longitudinal diffusion of cable, when sheath is poorly sealed or damaged, the moisture that is immersed in cable inside can be along the longitudinal diffusion of cable, cause whole cable to scrap, loss is enlarged.
And the cable of current existence or be that water proofing property is undesirable, or be exactly the high cost of realizing water proofing property.
The utility model content
For the problem that prior art exists, the purpose of this utility model is to provide a kind of water repellent electric cable, and this water repellent electric cable is when realization blocks water comprehensively, and cost compare is low.
A kind of water repellent electric cable that the utility model provides, it comprises conductor, insulating barrier and insulating sleeve, between described insulating barrier and described insulating sleeve, be provided with successively dry filler, the gasket for packing that blocks water and moisture-proof layer radially, further the inwall in described insulating sleeve is embedded with bagged dryer.
Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:
A kind of water repellent electric cable that the utility model provides, it comprises conductor, insulating barrier and insulating sleeve, between described insulating barrier and described insulating sleeve, be provided with successively dry filler, the gasket for packing that blocks water and moisture-proof layer radially, further the inwall in described insulating sleeve is embedded with bagged dryer; Described dry filler, the described gasket for packing that blocks water, described radially moisture-proof layer and described bagged dryer acting in conjunction have radially and vertical multilayer block-water effect, and the use of described dry filler and described bagged dryer is when reaching the enhancing block-water effect, do not produce again too much cost, thereby, a kind of water repellent electric cable that the utility model provides is when realizing that the front blocks water, and cost compare is low.
