Abstract

The invention provides a special strip for an ultrahigh-voltage cable and a production method of the special strip, and belongs to the technical field of cables. The special strip for the ultrahigh-voltage cable comprises a basic assembly and a reinforcing assembly. The basic assembly comprises a nylon layer and a rubber layer, the rubber layer is fixed on the outer wall of the nylon layer, and the reinforcing assembly comprises a flame-retardant layer, a tensile layer, an insulating layer, an antistatic layer, a wear-resistant layer and reinforcing ribs. During use, the insulating layer is attached to the wear-resistant layer to synthesize a special strip, an output shaft of a motor on the winding device is controlled to rotate reversely, the synthesized special strip penetrates through the stamping device, and layers on the special strip are tightly pressed together under the combined action of an upper die and a lower die of the stamping device. The special strip has the advantages of being flame-retardant, tensile, insulating, antistatic, wear-resistant, high in bearing capacity, high in reversible deformation, rich in elasticity and the like, and the applicability of the special strip is improved.

Description

technical field [0001] The invention relates to the field of cables, in particular to a special strip for ultra-high voltage cables and a production method thereof. Background technique [0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. [0003] Existing special strips for ultra-high voltage cables have poor flame retardancy and antistatic performance, poor load-bearing capacity, and poor applicability. Contents of the invention [0004] In order to make up for the above deficiencies, the present invention provides a special strip for ultra-high voltage cables and its production method, aiming to improve the problems of poor flame retardancy and antistatic function of the special strip, poor load-bearing capacity, and poor applicability. [0005] The present invention is achieved like this: [0006] In a first aspect, the present invention provides a special tape for extra-high voltage cables, i...
