Embodiment 1

[0039] like Figures 3 to 5 Shown, the manufacturing method of lightning protection cable joint of the present invention, it comprises the following steps:

[0040] a, to lightning cable 7 and branch cable thereof, carry out the insulating layer stripping of fixed distance;

[0041] b. Pass the joint 1 of the branch cable together with the metal wire core of the lightning protection cable through the C-type clamp, first tighten it in the forward direction, and then tighten it in the opposite direction with the C-type clamp next to it;

[0042] c. Use a hydraulic crimping machine to start pressing from the branch cable joint 1. At least one-third of the molds need to be stacked. Each mold should be pressed above 70 MPa and held for 10 seconds; until it is clamped. The C-type clamp is fully pressed;

[0043] d. Apply cable structural adhesive 2 to the crimping part of the branch cable, wait for the cable structural adhesive 2 to solidify and fix, and then insert the Y-shaped h...

Abstract

The invention relates to a manufacturing method of a lightning-protection cable joint. The manufacturing method comprises the steps of carrying out connecting of a lightning-protection cable branch, processing of the branch connecting position, and overall packaging of the connecting joint. The manufacturing method of the lightning-protection cable joint provided by the invention is reasonable inprocess design, convenient to operate and reliable; and the manufactured lightning-protection cable joint is high in pressure-resistant grade, high in lightning protection effect, stable in connectingsealing performance, capable of preventing from electricity leakage and creepage, high in surface voltage resistance, and capable of effectively improving the voltage resistance level and the breakdown condition of a lightning protection system.

Description

technical field [0001] The invention relates to a lightning protection cable, in particular to a method for manufacturing a lightning protection cable joint. Background technique [0002] The lightning protection system involved in the present invention is mostly used in the wind energy industry at present. Wind energy is the energy with the most commercial value in the utilization of clean energy in the world, and the development of lightning protection technology for blades is also very rapid. One of the most critical issues in the reliability of wind turbines is blade lightning protection technology. With the rapid development of wind turbines and the increase in power generation, the probability of lightning strikes on wind turbines will also increase proportionally. The most dangerous parts of a wind turbine are the rotor blades. Therefore, its good lightning protection design is the decisive factor to ensure the continuous and stable operation of wind turbines.
