The VFD cables are used in power transmission system from variable frequency drives to AC motor with rated voltage upto and including 26/35kV. It has good shielding properties, anti-electrostatic coupling, anti-electromagnetic induction, anti-electromagnetic wave, anti-poor grounding and anti-electromagnetic interference, etc. The cable is intended for fixed installation and laying outdoor and indoor, direct burial, cable conduit and trench.
