ZIP Intermediate Class Polymer Arresters

The type “ZIP” intermediate class arresters offer the benefits of polymer housings for system voltages up to 161 kV.

The arresters are approximately 1/5 the weight of the porcelain equivalent. Handling and installation become much easier tasks. Also, the risk of damage to the housing is reduced compared to porcelain.

Features:

• The design consists of a number of metal oxide valve elements contained within a fibreglass winding and then inserted into the polymer housing. ZIP arresters are shipped as single units for all ratings
• There is no need to combine sections, even for the 144 kV duty cycle rating
• The metal oxide valve elements combine excellent protective characteristics with steady state performance to maximise protection over many years of service
