Three-layer Co-extrusion Dry Cross-linking Production Line

1. Description

☀ For 10-132kv polyethylene power cable compressed copper or aluminum stranded cable core: internal screen,

insulation, external screen three layer co-extrusion and cross-linking;

☀ This line is used for making medium and high voltage power cable and it consists of pay-off stands, take-up stands,

accumulator, caterpillars, extruders, three layers crosshead,tubes, sag device and other single machines.

☀ Dry chemical cross-linking method can produce 10-132KV PE cable, the form of the distribution tube is catenary type,

the cross-linking tube adopts short circuit heating, nitrogen cross-linking and water cooling.

☀ Internal and external shielding and insulation of the cable can extrude and continuous produce at the same time.

☀ In the cross-linking pipeline, the cable can occur chemical cross-linking reaction with certain process line speed

(reaction time) at the protection of high temperature, high pressure and nitrogen. Cooling gradually in the pre-cooling

tube, cooling in the water cooling pipeline, and the final product are produced to ensure the cable has a good electrical

insulation property, anti-aging property and thermal mechanical property.

☀ Using MMI+PLC control system, each production process data can be online: storage, retrieval, modification, intuitive

operation, simple, convenient.
