Embodiment Construction

[0022] Composite shielded power cables are mainly composed of conductors, insulating layers, and shielding layers, and some types of cables are equipped with protective layers. Single-core cables wrap the shielding layer outside the insulation layer of the wire; multi-core cables wrap the shielding layer outside the insulation layer of each core wire; or set a shielding layer on the outer protective layer of the multi-core cable; Wrap the shielding layer, and set the shielding protection layer on the outer protective layer of the multi-core cable to form a double shielding layer. The single-core shielded power cable consists of a conductor 1, an insulating layer 2, and a shielding layer 3. The insulating layer 2 is made of polyvinyl chloride, polyethylene, cross-linked polyethylene, foamed polyethylene, fluoroplastic, polyamide, polypropylene or polyester plastic; the shielding layer 3 is made of nano-carbon particles, nano-graphene, four Iron oxide particles, carbonyl iron n...

Abstract

The invention discloses a composite material shielding power cable. The composite material shielding power cable is divided into two classes including the single-core cable and the multi-core cable, the single-core cable is wrapped by an insulating layer, and the insulating layer is wrapped by a composite material shielding layer; the multi-core cable is characterized in that a shielding layer is arranged outside each core wire insulating layer; or a shielding layer is arranged in a protection layer; or shielding layers are arranged outside the insulating layer and in the protection layer at the same time. The composite material shielding power cable is simple in structure, and the shielding materials are light; meanwhile, the anti-electromagnetic interference capacity of the cable can be effectively improved, potentials can be balanced, power supply quality can be improved, and electromagnetic environment influences generated by electrification wires can be reduced.

Description

technical field [0001] The invention relates to the field of power cables, in particular to power cables based on composite material shielding. Background technique [0002] With the development of urbanization, industrialization and informatization in our country, people's demand for electricity is increasing day by day. Power cables are mainly used for the transmission and distribution of electric energy. They are often used in underground power grids, outgoing lines of power stations and substations, underwater transmission lines, and internal power supply lines of industrial enterprises. Power cables are cable products used to transmit and distribute high-power electric energy in the main lines of power systems, including various insulated power cables with voltage levels of 0~500kV and above. [0003] Existing power cables are used to transmit electric energy in AC and DC power lines, and generally have weak anti-electromagnetic interference capabilities, especially th...
