Product details
Application Scenarios: Designed for PLN distribution networks in Indonesia, industrial parks, mining sites, photovoltaic step-up substations, switchgear substations, and island microgrids.
Product Configuration: P-288; Model RMU; Rated voltages: 12 kV, 24 kV, 40.5 kV; Frequency: 60 Hz; Insulation levels: 48 kV, 79 kV, 118 kV.
Indonesia-Specific Adaptation: Compact substation layouts support either ring-main or gas/solid-insulated configurations; for coastal and high-humidity environments, condensation resistance, creepage distance, corrosion protection, and cable termination interface compatibility must be verified.
