Abstract

The invention relates to a novel power cable structure belonging to the technical field of basic electronic components, and specifically relates to improvement of a power cable. The invention provides a novel power cable structure with low manufacturing cost and high environmental protection property. The novel power cable structure includes a central conductor layer, a semiconduction warping tape, an extruded semiconduction conductor shielding layer, a direct current insulating layer, an extruded semiconduction insulating and shielding layer, a first semiconduction waterproof buffer strip, a stainless protection layer, a second semiconduction waterproof buffer strip, a wrinkle copper sleeve, a polyethylene inner sheath, an armor layer and an oversheath. The novel power cable structure is characterized in that the external of the central conductor layer is successively provided with the semiconduction warping tape, the extruded semiconduction conductor shielding layer, the direct current insulating layer, the extruded semiconduction insulating and shielding layer, the first semiconduction waterproof buffer strip, the stainless protection layer, the second semiconduction waterproof buffer strip, the wrinkle copper sleeve, the polyethylene inner sheath, the armor layer and the oversheath, wherein the armor layer is formed by an inner layer plastic extrusion steel wire layer and an outer layer plastic extrusion steel wire layer.

Description

technical field [0001] The invention belongs to the technical field of basic electronic components, and in particular relates to an improvement of a power cable. Background technique [0002] In the two-terminal DC transmission system or the multi-terminal DC transmission system, the power transmission between the converter stations can adopt three types of lines: overhead lines, cable lines and overhead-cable hybrid lines. Domestic thyristor-based phase-controlled converter high-voltage DC transmission is mostly used for large-capacity, long-distance, point-to-point power transmission. The converter stations at both ends are far away from the city center, and the voltage level is 500 kV and above. Both ends are connected by overhead lines. No DC cables are used. High-voltage direct current transmission (VSC—HVDC) based on voltage source converters, also known as flexible direct current in China, has the advantages of power supply to passive networks, no commutation failure...
