Three-layer Cross-linked Cable Extrusion Line
Application
This three-layer cross-linked cable extrusion line is nitrogen & water cooling cross-linked cable production line. It is suitable for manufacturing 6 KV to 35 KV cross-linked polyethylene insulated cable.
Product Features
Advanced design and diversified production modes guarantee the high quality finished cables.
Advantages
The extrusion machine requires low investment but offers high efficiency. It is the optimal extruding machinery for high-voltage cable producing.
Update and Improvement
1. The three-layer cross-linked cable extrusion machine can choose mold and die sleeve, so that it can produce cables of different specifications without stopping.
2. Standard or high speed wire can be configured to the extruder for different application requirement.
3. Threes sets of extruding machines apply the sleeve welded copper tube rather than the spinal copper tube for cooling.
4. Cooling system of the extruding equipment uses the ferrule fitting connection. This type of connection is easy and convenient to install.
5. To improve the dielectric strength and quality of the cables, the three-layer cross-linked cable extrusion line uses nitrogen cooling system rather than the water cooling system.
