The electric power submarine cable of the utility model can solve the safety problem of high pressure submarine cables of prior arts for test.
Description
Technical field
The utility model belongs to the high-tension cable field, particularly relates to the concentric high voltage test of a kind of 110kV with electric power sea cable.
Background technology
The submarine cable engineering is laid need be connected with access point after landing at submarine cable and is carried out circuit on power system expection test; Because debarkation point and access point have certain distance; Test requirements document has extra large cable to be connected with the ground wire long cable section of ingoing line; Satisfy test high-voltage transmission and test current conduction, simultaneously, satisfy removable, good coiling property, alternating bending property, multifrequency and time lay and to pull resistance to wear and seabeach bank water-tight corrosion-proof property.
Summary of the invention
The utility model technical problem to be solved provides the concentric high voltage test of a kind of 110kV with electric power sea cable, to solve the problem of prior art mesohigh submarine cable fail safe.
The utility model solves the technical scheme that its technical problem adopted: provide the concentric high voltage test of a kind of 110kV with electric power sea cable; Comprise copper conductor core, conductor shield, crosslinked polyetylene insulated layer, insulation screen, resilient coating, ground wire sandwich layer, semi-conductive tape and oversheath; Described each layer cross section is a concentric circles; Wherein, The copper conductor core is positioned at round center, its outer ring and is surrounded by conductor shield, crosslinked polyetylene insulated layer, insulation screen, resilient coating, ground wire sandwich layer, semi-conductive tape and oversheath from inside to outside successively, and described ground wire sandwich layer is made up of around concentric circles identical round conductor.
