Problems solved by technology

[0002] In the cable laying from the nacelle to the tower of the wind turbine, the cable devices such as the generator stator side cable, the rotor side cable, and the power supply cable for the nacelle are all fixed with cable mesh sleeves. Most of the current cable mesh sleeves use steel wire mesh sleeves. The body is in the form of a grid, which will be continuously tightened under the gravity load. Therefore, after the cable is suspended for a period of time, the steel wire mesh sleeve may continue to tighten due to the gravity load of the suspended cable, and it will be pulled into the cable insulation layer, causing the cable insulation to be damaged. current short circuit
In addition, the friction between the steel wire mesh sleeves on the suspension cable will cause the steel wire mesh sleeves to draw wires, and the steel wires will damage the cable insulation layer and cause a short circuit

Abstract

A wind power cable clamp hanger comprises a cable hanger body, a cable pretightening hollow bolt and a cable hanger bolt-equipped hanging ring. The cable hanger body and the cable pretightening hollow bolt are internally provided with a cable protecting insulator. The lower end of the cable hanger body is conical, and the upper end is internally provided with a screw thread which is locked with the outer screw thread of the cable pretightening hollow bolt. The upper end of the cable hanger body is provided with two symmetrical circular through holes. The cable hanger bolt-equipped hanging ring penetrates the circular through holes and is combined with the cable hanger body. The wind power cable clamp hanger can be adjusted and tightened according to different dimensions of the cables and can realize good fixation on the cables with different dimensions. Furthermore the wind power cable clamp hanger has advantages of firm and tidy arrangement, attractive appearance, simple assembling and convenient application.

Description

technical field [0001] The invention relates to the technical field of cable traction protection, in particular to a wind power cable clamp hanger. Background technique [0002] In the cable laying from the nacelle to the tower of the wind turbine, the cable devices such as the generator stator side cable, the rotor side cable, and the power supply cable for the nacelle are all fixed with cable mesh sleeves. Most of the current cable mesh sleeves use steel wire mesh sleeves. The body is in the form of a grid, which will be continuously tightened under the gravity load. Therefore, after the cable is suspended for a period of time, the steel wire mesh sleeve may continue to tighten due to the gravity load of the suspended cable, and it will be pulled into the cable insulation layer, causing the cable insulation to be damaged. Current short circuit. In addition, the friction between the steel wire mesh sleeves on the suspension cable will cause the steel wire mesh sleeves to d...
