Example Embodiment

[0024] like figure 1 As shown, an environment-friendly marine power cable according to the present invention includes a cable core, which is composed of a water body 1 and a semi-conductive shielding layer 2, an ultra-clean insulating layer 3, and an ultra-clean insulating layer that are sequentially squeezed outside the water blocking body 1. It consists of a smooth insulating shielding layer 4; the cable core is covered with a semi-conductive buffer water-blocking layer 5, a lead sheath 6, an aluminum alloy wire armor layer 7, a semi-conductive buffer layer 8, a galvanized steel wire armor layer 9 and The polypropylene rope layer 10 is extruded with a polyethylene outer sheath 11 outside the cable core.

[0025] The water-blocking body 1 is formed by adding water-blocking yarn with strong water-blocking performance when layering and compressing the conductor and twisting in at the same time.

[0026] The present invention provides an environment-friendly marine power ca...

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:...
