Embodiment Construction

[0018] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.

[0019] Such as figure 1 As shown, a cold-resistant torsion-resistant flame-retardant wind energy power cable is composed of a number of aramid wire conductor parts 1 and a number of annealed copper wire conductor parts 2 twisted into strands 3 at a certain pitch, and then the strands 3 are twisted according to a certain pitch Re-twisted in the same direction as a flexible conductor, the flexible conductor formed by strands 3 in the same direction is wrapped with isolation tape 4 at a certain coverage rate, and insulation 5 is extruded outside the isolation tape, and insulation 5 is extruded for protection Set of 6.

[0020] Such as figure 1 As shown, the insulation 5 is extruded by a rubber extruder to a certain thickness outside the isolation belt 4, and its material is ethylene-propylene rubber.

[0021] Such as figure 1 As shown, the sheath 6 is ...

Abstract

The invention provides a cold-resistant twisting-resistant flame retardant wind energy power cable. According to the cable, a plurality of aramid yarn conductors and a plurality of annealed copper wire conductors are stranded into strand wires according to a certain pitch, the strand wires are subjected to compound stranding according to a certain pitch to form flexible conductors in the same direction, an isolation belt is wrapped outside the flexible conductors formed by conducting compound stranding on the strand wires in the same direction according to a certain coverage rate, an insulation layer is extruded outside the isolation belt, and a sheath is extruded outside the insulation layer. The cold-resistant twisting-resistant flame retardant wind energy power cable is excellent in resistance to flames, oil, ultraviolet light, corrosion, low temperature and twisting, thereby being capable of guaranteeing the performance requirement of wind power generation for the power cables.

Description

technical field [0001] The invention relates to a cable, in particular to a cold-resistant torsion-resistant flame-retardant wind energy power cable. Background technique [0002] At present, the conventional wind energy cables are mostly wrapped with an isolation belt outside the conductor, then extruded with a layer of insulation and a layer of sheath. For neoprene or chlorinated polyethylene. With people's attention to renewable energy, the wind power generation industry has developed steadily. According to preliminary statistics from the China Wind Energy Association, in 2013 my country's newly installed wind power capacity was 16.1 million kilowatts, a substantial increase of 24% compared with 1296 kilowatts in 2012. The installed capacity has exceeded 90 million kilowatts. As a key supporting product for wind power generation, wind energy cables have been widely used with the rapid development of wind energy utilization, while conventional wind energy cables have unsa...
