Problems solved by technology

[0002] In terms of high-voltage power and signal transmission, there are two major technical problems in the cables used in the existing port container cranes and large cranes in steel mills or power plants: first, the cables will produce electrical induction during high-voltage power and signal transmission; Second, the existing cables often need to be stored in coiled (mobile) type under 10KV high voltage, and in the continuous working state of reciprocating coiling, the internal structure of the cable is easily affected by external factors such as continuous coiling and bending. Influence, causing component displacement, twisting, stress concentration and other mechanical damage caused by broken core

Abstract

The invention relates to an electro-optic compound port machine pony roll high-voltage cable, which consists of three main high-voltage wire cores, an optical cable, an earthing core, a wadding core, a saddle-shaped skeleton strip, reinforcing layers and an outer sheath. The main high-voltage wire cores, the optical cable, the earthing core and the wadding core are positioned on the saddle-shaped skeleton strip; the optical cable, the earthing core and the wadding core are respectively positioned between two adjacent main high-voltage wire cores of three main high-voltage wire cores; and the reinforcing layer are covered outside the main high-voltage wire cores, the optical cable, the earthing core and the wadding core. A liner layer is filled in the interstice in the reinforcement layer, the outer sheath is arranged outside the reinforcing layer; in addition, the invention also relates to a method for producing the cable. The cable of the invention has the characteristics of no electric induction, less space occupation and long service life.

Description

technical field [0001] The invention relates to a cable used for a large mechanical device, in particular to a photoelectric composite port machinery coiled high-voltage cable, and in addition, the invention also relates to a production method of the cable. Background technique [0002] In terms of high-voltage power and signal transmission, there are two major technical problems in the cables used in the existing port container cranes and large cranes in steel mills or power plants: first, the cables will produce electrical induction during high-voltage power and signal transmission; Second, the existing cables often need to be stored in coiled (mobile) type under 10KV high voltage, and in the continuous working state of reciprocating coiling, the internal structure of the cable is easily affected by external factors such as continuous coiling and bending. Impact, resulting in component displacement, twisting, stress concentration, etc., causing mechanical damage to broken ...
