Lightning impulse-resistant anti-thunder cable and fabrication method thereof

Abstract

The invention relates to a lightning impulse-resistant anti-thunder cable and a fabrication method thereof. A cross-linked polyethylene insulation filling core is arranged at the innermost layer of the anti-thunder cable, a copper wire sparse winding conductor is sparsely wound around an outer layer of the cross-linked polyethylene insulation filling core, a copper strip wrapping layer wraps an outer layer of the copper wire sparse winding conductor, a cross-linked polyethylene insulation layer wraps an outer layer of the copper strip wrapping layer, a copper wire sparse winding conductor shielding layer is arranged at an outer layer of the cross-linked polyethylene insulation layer, a copper strip wrapping shielding layer wraps an outer layer of the copper wire sparse winding conductor shielding layer, and an outer sheath wraps an outer layer of the copper strip wrapping shielding layer. The cable has the capability of high-impact voltage resistance and is applicable to equipment suchas a signal transferring and power transmission wire; and by the anti-thunder cable, the grounding reliability can be improved, the lightning current and ground potential are reduced, the back flashover and the step voltage are prevented, and damage caused by thunder is prevented or reduced.

Description

technical field [0001] The invention relates to the technical field of design cables, and specifically designs a lightning shock-resistant lightning protection cable and a preparation method thereof. Background technique [0002] As we all know, lightning, as an unpredictable weather phenomenon in nature, generates a huge current flow at the point of lightning strike, and the inevitable lightning discharge has a great impact or even damage on the fields of electric power, communication, construction, etc. Therefore, being struck Objects or cable jackets can be easily damaged during a lightning strike. Therefore, when connecting the electrodes, a lightning shock-resistant and lightning-proof cable is needed. [0003] At present, the design defects and deficiencies of lightning protection cables in the domestic cable industry. When traditional cables are struck by lightning, large lightning waves will invade substations or buildings along lines, metal pipes, etc., causing pre...
