HV Surge Arresters Aluminium Grading Rings

Aluminum alloy potentialring/grading ring application: silicone housing arresters in Cage Design of the SBKC series for applications up to 420 kV.

November 23, 2020

Fibreglas reinforced plastic rods (FRP) are fixed in the arrester terminals and form a kind of cage around the metaloxide varistor blocks which provides a high mechanical stability to the arrester. The direct moulding of the active part with LSR silicone prevents from any moisture ingress and ensures a high reliability. We use high quality LSR silicone which keeps its hydrophobic and UV-resistant/non ageing properties over the complete service life and ensures excellent artificial pollution performance.

SBKC arresters in Cage Design are suitable for applications with advanced mechanical requirements and offer an outstanding price-performance ratio. They can be installed in substations in stationary or suspended installation and are best adapted for use as line arresters for protection of transmission lines. High level and stable manufacturing quality on newest machinery as well as testing with state-of-the-art test equipment assure a long service life.
