HUALUO CABLE
Medium Voltage Cables

Product Overview:
Medium voltage cables use chemical or physical methods to convert polyethylene molecules from a linear molecular structure to a spatial network structure, transforming thermoplastic polyethylene into thermosetting cross-linked polyethylene, greatly improving its mechanical properties, thermal aging properties, and environmental stress cracking resistance, and having excellent electrical properties.
Features:
- The normal operating temperature of the conductor is high.
- Simple structure, small outer diameter, light weight, easy to use.
- It is not limited by the laying drop.
