Novel cable for wind driven generator

Abstract

The invention provides a novel cable for a wind driven generator. The cable comprises a conductor. An isolating layer is arranged on the outer side of the conductor. An insulating layer is arranged on the outer side of the isolating layer. An aramid fiber layer is arranged on the outer side of the insulating layer. A sheath layer is arranged on the outer side of the aramid fiber layer. According to the structure, a cable core is formed. A plurality of cable cores are stranded and then wrapped with a lapped covering layer. An ethylene propylene rubber or silicon rubber insulating layer is arranged on the outer side of the lapped covering layer. A ceramic silicon rubber fire-resistant layer is arranged on the outer side of the ethylene propylene rubber or silicon rubber insulating layer. A waterproof layer with the waterproof function is arranged on the outer side of the ceramic silicon rubber fire-resistant layer. An oil-proof layer with the oil-proof function is arranged on the outer side of the waterproof layer. A halogen-free rubber sheath layer free of pollution is arranged on the outer side of the oil-proof layer. A filling layer is arranged on the inner side of the lapped covering layer. The cable is simple in structure and excellent in heat resistance, oxidation resistance, ageing resistance, ozone resistance, weather resistance, flame-retarding property and oil resistance.

Description

technical field [0001] The invention relates to a cable, in particular to a new type of cable for wind power generators. Background technique [0002] The use of wind energy has a long history, and the use of wind power can save a lot of energy. The current wind power generation is generated by wind power generators, and then transmitted to the transformer room through special cables. As we all know, wind power generators are mostly located in open wind-rich areas , the working environment is quite harsh, wind and rain, sun and rain, hot summer and cold winter, and corrosion such as salt spray. In the cold winter, torsion at low temperature can easily crack the cable outlet, causing the cable to be damaged and cannot be used. In the hot summer, especially at the seaside, due to the relatively large salt spray, the outer layer of the cable is easily corroded, and Ordinary cables do not have properties such as fire resistance, water resistance, and oil release.
