| Series | RDS |
RDS series V-type center break disconnector features a compact V-configured insulator arrangement per phase, reducing footprint in space-constrained outdoor switchyards. Suitable for voltages up to 145 kV with 2000 A rated current and 44 kA short-time withstand. Two moving insulators per phase in V-configuration provide reliable operation with simple mechanical interlock. Built-on earth switches available on one or both sides. Suitable for manual or motor-operated mechanism.
