The power undersea cable comprises a copper conductor (1), a conductor shielding layer (2), a cross-linked polyethylene insulating layer (3), an insulating shielding layer (4), a buffer layer (5), an earth wire core (6), a semiconductive band (7) and an outer sheath (8), wherein the cross section of each layer is a concentric circle; the copper conductor core (1) is arranged in the center of the concentric circle and the conductor shielding layer (2), the cross-linked polyethylene insulating layer (3), the insulating shielding layer (4), the buffer layer (5), the earth wire core (6), the semiconductive band (7) and the outer sheath (8) are arranged outside the copper conductor core (1) from inside to outside in sequence; the earth wire core (6) is formed in such a manner that the same circular conductors enclose the concentric circle; the conductor shielding layer (2) and the insulating shielding layer (4) are made of semiconductive shielding materials; the buffer layer (5) is made of semiconductive waterproof buffer bands; and the outer sheath (8) is made of polyethylene. By using the power undersea cable, the problem of safety of the high voltage undersea cables for the test in the prior art can be solved.
Description
Technical field
The invention belongs to the high-tension cable field, particularly relate to a kind of 110kV with the core high voltage test 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
Technical problem to be solved by this invention provide a kind of 110kV with the core high voltage test with electric power sea cable, to solve the problem of prior art mesohigh submarine cable fail safe.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of 110kV with the core high voltage test 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 for together core is round; Wherein, Copper conductor 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 centered on the core circle by identical round conductor to be formed.
Described conductor shield and insulation shielding layer material are semiconductive shieldin material.
Described cushioning layer material is the semiconductive buffer strip that blocks water.
Described jacket material is a polyethylene sheath material.
Beneficial effect
High-voltage electric power circuit test high-pressure side inlet wire be will be used for, transformer station and tested sample connected.Existing conductor can satisfy the transmission of high-tension current, and ground wire sandwich layer reliable ground is arranged again, guarantees the safety of personnel and equipment.Solved the problem of in the problem and the Voltage Cable Lines Construction of access point connection carrying out circuit expection test the pre-stage test connection being installed after the high pressure submarine cable lands; The shortcoming that power cable, ground wire separately lay when having improved test, properties of product are safe and reliable, easy to use.
