General
This kiosk compact substation combined switchgear and trasnformer, it can use SF6 insulation switchgear for MV, and both dry type transformer or oil immersed type distribution transformer, for LV output also have switchgear for control.
It is mini subatation, suitable for outdoor, for power supply and control.
Transformer use high quality transformer oil, high quality CRGO core, primary and secondary use pure electrolytic copper, both winding and core have shielding processing.
Switchgear for Medium voltage and Low voltage. for MV side can make by SF6 insulation, or air insulation, with VCB control, for LV side use ACB as main breaker.
