RSTI-SA-10 is a raychem screened, separable surge arrester up to 41 kV.

The screened gapless surge arrester is a “T“-shaped product. It is designed for direct connection onto outer cone bushings in accordance to EN50180 or EN50181 with interface type “C” or for parallel connection mating to the rear entry of the base screened connector system RSTI designed for system voltage up to 41 kV.
The insulation of the screened surge arrester is 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  nintentional 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 conncector and surge arrester exceeds CENELEC HD 629.1 S2 requirements, which includes BS, VDE and other
international specifications. Easily accessible rear plug with capacitive test point. Few accessories required for system test and earth connection.
Complete kit including screened surge arrester, threaded pin and ground lead for three phases facilitates installation and storage.
