Flat cable production line

Abstract

The invention relates to horizontal cable production equipment, namely a horizontal cable production line, and especially relates to a horizontal cable production line for high-voltage and ultrahigh-voltage cables, in particular to a horizontal cable production line for producing three-layer extruded high-voltage cabtyre cables with voltage being 35KV or higher than 35KV and producing crosslinked polyethylene cables with voltage being 110KV or higher than 110KV. The horizontal cable production line comprises a pay-off frame (1), an extruder (3), a head (4), a heating pipeline (5) and a take-up mechanism and is characterized in that the heating pipeline (5) is filled with silicon oil (13) and extends horizontally. The horizontal cable production line has the advantages that the horizontal cable production line can be constructed on the flat ground, and high buildings or high towers are omitted, so that investment is low and production is quick; the silicon oil with the specific gravity approximate to that of a cable is used as a medium, expansion and shrinkage ratio is extremely low, and the cable can pass through stably without eccentricity; since steam and nitrogen are not needed, associated equipment is omitted, and low energy consumption and zero emission are realized; the silicon oil is high in thermal efficiency, and the vulcanization crosslinking process can be completed at low temperature, so that aging is avoided; and vulcanization crosslinking sharing is realized, ultrahigh-voltage high-quality cables can be produced, and China's cable production capacity and level are greatly promoted.

Description

technical field [0001] The invention relates to a cable production equipment, namely a flat cable production line, especially a flat production line for high-voltage and ultra-high-voltage cables, especially for the production of three-layer co-extruded high-voltage rubber-sheathed cables of 35KV and above and the production of 110KV and above The horizontal production line of XLPE cables. Background technique [0002] Cables include power cables, communication cables, mining cables, mobile cables, marine cables, submarine cables, high-voltage and extra-high-voltage cables, optical cables, heating cables, lightning protection cables, etc., and are important equipment for power transmission and information transmission. The cable is composed of a wire and a wrapping layer. The wrapping layer is mainly an insulating layer surrounded by rubber, resin, polyethylene and other materials. Some also have a conductive shielding layer and a protective layer with high strength. The pr...
