Utility model content
For the problem solving above-mentioned existence, the utility model discloses a kind of waterproof cold-resistant power cable, this technical scheme simple in construction, compact, and the cold-resistant power cable of one that normally can use under severe low temperature (-55 DEG C) environment again on the premise of there is water-tight corrosion-proof interference free performance.
To achieve these goals, the technical solution of the utility model is as follows, waterproof cold-resistant power cable, it is characterized in that, described power cable includes at least three major insulation cores and a ground connection core, filling packed layer between described core, described power cable is disposed with conductor, conductor water blocking layer, insulating barrier, packed layer, the belting layer that blocks water, screen layer and restrictive coating from inside to outside.
As a kind of improvement of the present utility model, described core includes that conductor, water blocking layer and insulating barrier, the quantity of described conductor are (3～5) core.
As a kind of improvement of the present utility model, described conductor uses tinned copper conductor, and described insulating barrier uses cross-linking polyethylene materials to make.
As a kind of improvement of the present utility model, described packed layer uses waterproofing rope to make, and described packed layer is arranged between insulating barrier and belting layer.
A kind of improve as of the present utility model, described in the belting layer that blocks water formed by waterstop is wrapped.
As a kind of improvement of the present utility model, described screen layer is formed by tinned copper wire braiding.
As a kind of improvement of the present utility model, described restrictive coating is extruded by cold-resistant (-55 DEG C) butyronitrile complex and forms.
Relative to prior art, advantage of the present utility model is as follows, 1) whole Technical Design is ingenious, simple and compact for structure, 2) cable conductor in this technical scheme uses tin-coated copper core conductor, wrapped waterstop on conductor, insulant uses the crosslinked polyethylene insulation material of high-quality, fill and use waterproofing rope to fill, belting layer waterstop is wrapped to be tightened, waterproofing rope, waterstop material meets water expandable material containing one, when water is after cable socket enters, these materials can expand rapidly prevention moisture content and spread along cable, by arranging double-deck water blocking layer, can effectively prevent moisture penetration from entering cable inside thus reach the purpose that cable blocks water；Tinned copper wire braid shielded preservation antioxidation interference free performance is used to improve further；Restrictive coating uses cold-resistant (-55 DEG C) butyronitrile complex to extrude, cable can be made normally to work under cold low temperature environment, this cable adapts to the environment of-55 DEG C, range of application is more extensive, 3) this technical scheme has good cold-resistant low temperature resistant, anticorrosion interference free performance and moistureproof and waterproof performance, the fault that can effectively avoid cable to make insulating properties and electrical property reduce and cause due to moisture long term, has wide market prospect.
