Silicone rubber insulation wind power cable

Abstract

The invention relates to a silicone rubber insulation wind power cable comprising a lead and an insulating inner cladding, a shielding layer, an insulating armor layer and a protective layer which aresequentially coated outside the lead from inside to outside. The insulating inner cladding is of a double-layer insulating structure with a round inside and a square outside, an insulating frame is arranged between the inner layer and the outer layer to connect the inner layer and the outer layer, and the insulating armor layer is formed by sequentially bonding a plurality of armor strips with arc-shaped sections end to end. Compared with the cables in the prior art, the insulating inner cladding which is made of the silicone rubber material and has the inner-circular outer-square double-layer insulating structure and the insulating armor layer which is formed by sequentially bonding the armor strips are used, the electric insulating property of the wind power cable is greatly improved, and the stability of the chemical property and the physical and mechanical properties of the wind power cable is enhanced; the service life of the wind power cable is prolonged; and abrasion caused bymutual friction in the wind power cable is avoided through the protection layer with the positioning raised lines and the supporting raised lines, and the roundness of the appearance of the wind powercable is ensured.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a silicon rubber insulated wind power cable. Background technique [0002] As the power generation method with the most mature technology, the most large-scale development conditions and the most promising commercialization development among new energy sources, the development speed of wind power generation is impressive. As a supporting product for wind power generation equipment, wind power cables are becoming a new type of cable with huge market potential. [0003] There are currently no national and industry standards for wind power cables on the market, and there is no unified technical specification, and the performance of wind power cables manufactured by various companies varies. Existing wind power cables often have various problems such as poor insulation and being easily affected by weather and temperature, resulting in a low service life of the existing wind power cab...

AI Technical Summary

Problems solved by technology

Existing wind power cables often have various problems such as poor insulation and being easily affected by weather and temperature, resulting in a low service life of the existing wind power cables, which not only brings unnecessary economic losses to users, but also brings great harm to the users. The safe operation of wind power cable equipment brings great hidden dangers
