Metal Oxide Varistors

Electrical Power Generation

Our AZA Series of MOV (metal oxide varistor) assemblies offers customised options for the overvoltage/surge protection of DC exciters and similar or allied systems. A wide range of Continuous Operating Voltages and system energies can be accommodated in robust and compact assemblies. These can be supplied as discrete units or configured on mounting plates for direct installation.

Electrical Power Distribution

We provide a range of Medium Voltage silicone housed Surge Arresters (ASM) and a unique complementary range (TISA) which functions as an arrester and support Insulator. Our SVL series provides protection from over-voltages on cable sheaths by the cross-bonding of the sheaths and the ground continuity conductor.

This range of 10kA Class 1 distribution arresters are fully tested and approved to EN 60099-4 and IEC 61109.
Numerous assembly accessories are available, details upon request.
