SJ65+150+90 Triple Co-extrusion Line Machine For 6-35kv CCV Line

1. Application: 

This line is equipped with 3 extruders and one common crosshead, capable of extruding three layers of conductor screen layer, insulation layer and insulation screen layer in one single operation. The finished MV cables support a voltage rage between 6Kv and 35kV, which are ideal for use in power distribution and transmission lines.

2. Technical Characteristics for the CCV Line

• Good overall stability of the equipment, cost effective with less secondary waste after putting into operation.
• Advanced technology of the whole equipment and the excellent processing prevent from the three leakage problems effectively.
• Die replacing at the front part of the head, convenient and efficient for die adjusting and replacing, no deviation when accelerating the speed.
• Professional installment and calibrating, which can meet high requirements of the line producing.
• Advanced technology of the electrical control for the whole set of the equipment and easy to operate.
• Advanced technology of the sag control for the production line & stable performance, productive maintenance free.
• Stable nitrogen & water control system, no stoppage & leakage & instability of the water level failures, producing without maintenance.
• Accurate temperature control system, no ageing problem of the material in long-time producing.
• Adopting encoder for speed testing, stable running with high precision & excellent synchronization.
• 10. Project of tracking management by professionals in the whole process, which ensures the production quality with guaranteed after-sale service.
