RAYCHEM RSTI SURGE ARRESTORS
Description
The screened gapless surge arrester are âTâ-shaped products. They are designed for direct connection onto outer cone bushings in accordance with EN50180 or EN50181 with interface type âCâ or for parallel connection mating to the rear entry of the RSTI base screened connector system designed for system voltage up to 41 kV.
Easily accessible rear plug with capacitive test point. The insulation of the screened surge arresters are made of a highly modified silicone rubber characterised by high tracking resistance, elongation at break and non-flammability.
A thin-walled screen is permanently bonded onto the insulation and protects the connection system against unintentional contact.
The active part is a metal oxide arrester which meets the requirements of IEC-60099-4 for separable and dead-front arresters.
The combination of screened connector and surge arresters exceeds CENELEC HD 629.1 S2 requirements, which includes BS, VDE and other international specifications.
Few accessories required for system test and earth connection. Complete kit including screened surge arresters, threaded pin and ground lead for three phases facilitates installation and storage.
