Embodiment

[0054] This embodiment discloses a fan bridge cable, refer to figure 1 As shown, the cable includes a cable core 4, an EPCV insulating layer 6 and a CPE sheath layer 12. The cable core 4 has multiple groups of conductors 2 twisted with each other, and the multiple groups of conductors 2 are filled with unvulcanized CPE rubber (i.e. Filler 8), the above-mentioned conductor 2 is a stranded conductor, and the above-mentioned stranded conductor is made by twisting multiple strands of copper wire. The direction of the layer monofilament strands is opposite, and the pitch ratio of the outermost layer of the strands is 6 to 8 times.

[0055] The outer side of each conductor 2 is covered with an insulating layer 6 , and the outer side of multiple conductors 2 is wrapped with a wrapping tape 10 and then covered with a sheath layer 12 on the outer side.

[0056] The above-mentioned EPCV insulating layer 6 is formed by extruding the insulating material on the outside of the conductor 2 ...

Abstract

The invention discloses a fan bridge cable, which comprises a cable core, an EPCV insulating layer and a flame-retardant CPE sheath layer. The insulating layer is formed by extruding insulating material on the outside of the cable core through a rubber extrusion machine. The ingredients of the insulating material include: Vulcanizing agent, rubber extruder includes low-speed extrusion and high-speed extrusion, the process conditions of low-speed extrusion are: the temperature of the feed port is 70-75°C, the temperature of the screw is 80-85°C, the temperature of the first section of the fuselage is 85-90°C ℃, the temperature of the second section of the fuselage is 90-95°C, the temperature of the head is 95-100°C; The temperature of the first section is 80-90°C, the temperature of the second section of the fuselage is 85-95°C, and the temperature of the machine head is 75-85°C; the speed of the rubber extruder is 9-20m / min, and the vulcanization pipeline of the rubber extruder is The steam pressure is 15-20bar. The fan bridge cable of the present invention has an insulation tensile strength of 12.3MPa, meets the oil resistance performance of PRI in UL1277, has the ability of power signal transmission and control signal transmission, and satisfies flame retardancy, high mechanical performance, cold resistance and oil resistance performance.

Description

technical field [0001] The invention relates to the technical field of power cable manufacturing, in particular to a fan bridge cable. Background technique [0002] Since the global oil crisis in the 1970s, major developed countries such as the United States and Western Europe have begun to formulate development plans for renewable energy in order to seek alternatives to fossil fuels such as oil and coal, and have invested a lot of money in research on the use of renewable energy. way. After years of research and practice, technologies related to renewable energy such as wind energy, water energy, and solar energy have gradually matured and been applied on a large scale. Among them, wind energy has become one of the renewable energy sources closest to commercialization except hydropower. Wind power generation has become the power generation method with the highest technological maturity, the highest scale development conditions and the best commercial development prospects ...
