Ultraviolet radiation crosslinked cable color separation processing technology and radiation focusing device

Abstract

The embodiment of the invention relates to an ultraviolet radiation crosslinked cable color separation processing technology and a radiation focusing device. The ultraviolet radiation crosslinked cable color separation processing technology comprises the following steps that: S1, colored tapes and a cable conductor are pretreated; S2, the colored tapes are added, so that the colored tapes and thecable conductor are attached to form a primary combined body of an integrated structure; and S3, the colored tapes and the cable conductor are extruded through an extruder in an insulated manner, andcooling and molding are performed after radiation crosslinking by ultraviolet rays is performed. According to the ultraviolet radiation crosslinked cable color separation processing technology and theradiation focusing device of the invention, color separation is carried out by adding the colored tapes, the influence of color separation of color masterbatch on the physical properties and electrical properties of an insulating material in the prior art is overcome; and the ultraviolet crosslinking technology has the advantages of reduced material cost, high production speed, stable quality, online pipelined crosslinking and the like.

Description

technical field [0001] The invention relates to the field of cables, in particular to an ultraviolet radiation crosslinking cable color separation processing technology and a radiation focusing device. Background technique [0002] In the relevant specifications of my country's electrical industry, it is clearly stipulated that the color of cables must be marked in accordance with relevant requirements for installation and later maintenance. In the existing power cables used for power transmission and distribution, generally the transmission power is large and the voltage is high, so the reliability requirements are also high. The insulation layer of the cable is relatively thick, and the electrical performance requirements are relatively high. Since the insulated cores of power cables must be able to meet the needs of processing and installation, they are generally distinguished by different colors. [0003] At present, the production batches of products of different speci...
