Description
The cage of glass-epoxy rods is moulded directly in LSR silicone, so there is no gas volume in the device and no pressure relief device is needed. The permissible mechanical load SSL is up to 4 kN·m. The series is available in Station Low, Medium and High versions (SL, SM, SH) to IEC 60099-4. In terms of price-to-performance ratio, SBKC compares favourably among substation surge arresters.

Questions and answers
What network voltage is the SBKC rated for?
The arrester is used in networks with a highest voltage Um of up to 420 kV, at substations and on overhead lines.
Does the arrester have a pressure relief device?
No, the cage is moulded in LSR silicone with no gas volume, so a pressure relief device is not needed.
What mechanical load can the SBKC withstand?
The permissible mechanical load SSL is up to 4 kN·m, for upright or suspended mounting.
