Product details

Application Scenarios: Suited for PLN distribution networks in Indonesia, industrial parks, mining sites, photovoltaic step-up substations, switchgear rooms, and island microgrids.

Product Configuration: P-290; Model GIS; 72.5 kV, 50 Hz, 182 kV (power-frequency withstand voltage), 385 kV (lightning impulse withstand voltage), 1250 A, IP67. Indonesia-Specific Adaptation: Compact substation configurations support either ring-main or gas/solid-insulated solutions; for coastal and high-humidity regions, condensation resistance, creepage distance, corrosion protection, and cable termination interface compatibility must be verified.
