Nkọwa Dị Elu: Na-akwado otu dị elu nke ọma, na-akwalite ịhụrụ maka resistor cabinet / arc suppression coil. Nke a na-akwalite ịkpalite ground fault current, ịkpalite overvoltages, ma ọ bụ ịkwalite ụdị oge ọkachamara nke ụdị nkọwa.
Ụdị Ọkachamara:
Impact Resistance: Designed to withstand the impact of unbalanced currents and zero-sequence currents generated by system single-phase-to-ground faults.
Low Losses: Employs high-quality silicon steel cores and advanced manufacturing processes to ensure low no-load and load losses.
Robust Insulation: Features a reliable high-voltage insulation structure with low partial discharge levels.
Excellent Protection: High enclosure protection rating (IP), providing effective dust and moisture resistance.Installation & Maintenance Simplified: Compact structure combined with the side-exit wiring design optimizes both on-site installation and subsequent maintenance operations.
