3.03 Interrupter
The circuit switcher shall use SF
6
single gap puffer interrupters. Arc assist type
interrupters are not acceptable. Each interrupter shall be provided with an
overpressure relief device and shall be field refillable. Hermetically sealed
interrupters are not acceptable due to the inherent dangers to purchaser’s
personnel associated with handling fully pressurized SF
6
devices during
installation and also due to potential hazards encountered during transportation
and offloading.
3.04 Insulators
The support insulators and the interrupter insulators shall be ANSI 70 gray in
color and either porcelain or composite in construction.
