For 12kV outdoor distribution projects, Dongfa Intelligent, a China-based manufacturer, offers a 12kV Outdoor Vacuum Circuit Breaker with rated currents of 630A and 1250A and short-circuit breaking capacities of 20kA, 25kA, or 31.5kA. The ZW32-12 and ZW32-12G models support different outdoor installation arrangements. They provide 42/48kV power-frequency withstand voltage, 75/85kV lightning impulse withstand voltage, and a mechanical life of 10,000 operations.

Dongfa Intelligent supplies 40.5kV Outdoor Pole-Mounted Vacuum Circuit Breakers for overseas 40.5kV distribution projects. The breaker supports 1250A/1600A rated current, 31.5kA short-circuit breaking capacity, and both 50Hz and 60Hz systems. It also provides 80/95kV power-frequency withstand, 185kV lightning impulse withstand, a 20,000-operation mechanical life, and a stainless steel control cabinet.

Dongfa Intelligent supplies 24kV Outdoor Pole-Mounted Vacuum Circuit Breakers for 24kV outdoor distribution systems. With a 630A rated current and 20kA short-circuit breaking capacity, the breaker provides 65/79kV power-frequency withstand and 125/145kV lightning impulse withstand. Its high insulation level is suited to outdoor line switching and fault interruption where 24kV system requirements need to be met.
