3EQ0 Surge Arresters with Silicone Housing Composite Voltage Surge Arrestors

We offer the 3EQ0 for rated voltages of up to 45 kV for applications in which a surge arrester in silicone housing is required in combination with directional pressure relief.

The surge arrester with the composite hollow core design uses silicone and fiberglass-reinforced plastic (FRP) as housing materials. The direct molding of the silicone onto the FRP hollow core ensures reliability, while an excellent special sealing of the flanges at both ends of the surge arrester effectively prevents partial discharges and moisture ingress. This guarantees decades of trouble-free operation.

The combination of silicone rubber and the fiberglass-reinforced hollow core also allows for outstanding mechanical stability.
