Environment-friendly type ocean power cable

Abstract

The invention discloses an environment-friendly type ocean power cable which comprises a cable core. The cable core is formed by a water resisting body, a semiconductive shielding layer, an ultra-clean insulating layer and an ultra-smooth insulation shielding layer, wherein the semiconductive shielding layer, the ultra-clean insulating layer and the ultra-smooth insulation shielding layer are arranged outside the water resisting body in sequence. A semiconductive buffering water resisting layer, a lead sheath, an aluminum alloy wire armor layer, a semiconductive buffering layer, a zinc-coated steel wire armor layer and a polypropylene rope layer wrap outside the cable core in sequence, and an outer sheath is further arranged on the outer most layer of the cable core in a pressing wrapping mode. According to the environment-friendly type ocean power cable, high-dielectric-property and super-purified insulating materials are selected as raw materials, the mode of gravity blanking is adopted in a hundred-grade purification room, the raw materials are prevented from any external tiny pollution completely, the facts that a three-layer co-extrusion process is clean and the insulating layer is free of any tiny impurities are guaranteed fully, and the risk that the cable is broken in cable operation is reduced.

Description

technical field [0001] The invention belongs to the field of power cables, and in particular relates to an environment-friendly marine power cable. Background technique [0002] my country is a large oceanic country with a sea area of ​​more than 3 million square kilometers and a coastline of 18,000 kilometers. There are more than 6,000 islands along the coast. There are rich submarine oil fields and natural gas in the shallow sea continental shelf. The coast is also an economically developed area in my country. The development of coastal islands urgently needs electricity. Due to the high cost and long period of construction of power stations, and the difficulty in fuel supply, the launch of this product will bring great convenience and improve efficiency to the power supply needs of small and medium-sized islands. [0003] At present, there are broad markets and application prospects for domestic and international submarine cables, mainly reflected in the following markets:...

AI Technical Summary

Problems solved by technology

[0014] At present, the shortcomings of the existing technology are that the service life of the submarine cable is short, and it cannot meet the high requirements for electrical performance and mechanical protection. The selection of raw materials cannot avoid any small pollution of the raw materials from the outside world, and the cable cannot be solved. Issues such as run-through risk
