Three-layer Co-extrusion Dry Cross-linking Production Line
1.Description:
For 10-132kv polyethylene power cable compression 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 andother 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 productsare 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;
