Abstract

The invention discloses a novel cable for a water-blocking power generator, and the cable consists of a control cable core, a water-blocking filling layer, an internal sheath layer, an aramid fiber braided shielding layer, an anti-torsion bearing reinforcing layer, an insulating layer, and an external sheath layer. The control cable core consists of a conductor, a butyronitrile insulating layer, a non-magnetic metal armored layer, a silver-plated copper wire shielding layer, and a metal fiber braided shielding layer. The internal sheath layer and the external sheath layer are low-smoke halogen-free polyethylene sheath layers. According to the invention, low-smoke halogen-free rubber which is resistant to temperature, oil, ultraviolet light and water is used for forming the cable sheath layers, thereby enabling the mechanical performance of the cable to be greatly improved. Meanwhile, when fire happens to the cable, no poisonous gas is generated. The cable can freely rotate along with a windmill.

Description

technical field [0001] The invention belongs to the field of cables, in particular to a novel cable for a water-blocking generator. Background technique [0002] Wind energy is a kind of clean and renewable energy. With the increasing shortage of energy, the essential difference between wind energy and fossil fuel energy existing in nature, such as coal, oil, natural gas, etc., is that it will not change with its own transformation and utilization. Reduction is an inexhaustible source of energy. [0003] Since the direction of the wind force is uncertain in nature, the direction of the fan also changes with the change of the direction of the wind force. Wind turbine cables and all electrical control and communication cables run from the nacelle through the tower until they are led to the ground control cabinet. If the wind direction changes frequently, it will cause serious twisting of the cable and also encounter rain on cloudy and rainy days. With the development of sci...
