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.
