High-voltage cross-linked cable structure characteristics

66~220kv high-voltage cross-linked polyethylene insulated power cables The structure has the following characteristics: 1. conductor: conductor stranded from copper or aluminum single wire, 800mm2 cross-section of the conductor below the die-pulling tightly compressed round stranding process, with a smooth surface, good roundness, tightness coefficient, etc. 800mm2 conductor die-pulling tightly compressed round stranding or splitting the conductor structure. 800mm2 cross-section of the conductor structure is used to split the conductor to reduce the conductor skin effect. Conductor structure, in order to reduce the conductor skin effect, improve the transmission capacity of the cable. 2. Internal and external shielding: conductor shielding and insulation shielding semiconducting materials are used for crosslinking, ultra-smooth, and can adapt to the three-layer co-extruded imported materials, insulation shielding for the non-peelable type of material to ensure that the insulation layer and the close combination of the insulating layer. 3. Insulation: Insulation is applied to ultra-high-voltage cables with ultra-purified cross-linked polyethylene imported material, and with the inner and outer shielding extruded at the same time. 4. Waterproof layer and buffer layer: if the cable has longitudinal waterproof requirement, according to the different occasions of use, the waterproof structure of metal jacket plus buffer layer or comprehensive sheath plus buffer layer can be selected, and the waterproof layer is made of imported material with water-absorbing and expansion. 5. Metal shield or metal sheath: sparsely wound copper wires or lead packages are used, and the crumpled lead packages can be processed as well, in order to satisfy the requirements of mechanical properties and short-circuit capacity. 6. The use of lead or wrinkled lead package, can greatly improve the radial waterproof capacity. 6. isolation layer: this layer mainly plays a metal sheath and plastic sheath isolation, can be used paint, waterproof tape or other winding structure.-7, on the BBC Electronic Products Network platform related to the introduction and sales of products brief: BBC Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand which connectors | wiring harness | wire and cable product solutions that we can provide, please contact our Division below!
