Tridelta Surge Arrester
Design directly derived from VARISIL Type HE Distribution arrester range
Active part stacked with high energy metal oxide resistors of the size of Distribution blocks but providing the electrical performance of Station blocks
Wrapping made of a triple layer composite structure for enhanced mechanical strength
Insulation ensured by silicone rubber housings with alternating sheds for increased creepage distance
Built with two electrical units from 39 kV rated
