METHOD AND APPARATUS MANUFACTURING EXTRA HIGH VOLTAGE CABLE CORE USING TWO STEP EXTRUDING PROCESS FOR IMPROVING LINE SPEED AT VCV LINE

摘要

In the present invention, after extrusion of a part of the internal semiconductor and the insulator to the conductor in the vertical line process of the VCV line divided into a vertical line process and a horizontal line process around the turn pulley, crosslinking and cooling is performed, and the horizontal line process To extrude the remaining portion of the insulator and the outer semiconductor into an ultra-high voltage cable core consisting of a conductor, an inner semiconductor, and a part of the insulator, and then performing crosslinking and cooling to improve the flux of the VCV line. It provides a method and apparatus for producing an ultra-high voltage cable core using.;The method and apparatus for producing an ultra-high voltage cable core using a two-stage extrusion process for improving the speed of the VCV line of the present invention has a speed improvement effect of about 60% or more, compared with the case of using a conventional VCV line that performs triple co-extrusion. Have Therefore, the production speed can be greatly improved even without increasing the line height through facility investment.;Ultra High Voltage Cable, Conductor, Internal Semiconductor, Insulator, External Semiconductor, VCV Line, Vertical Line, Horizontal Line, Turn Pulley, Two Stage Extrusion
