Best for:
Suitable for utility distribution points, rural overhead distribution, agricultural service and outdoor single phase power supply projects requiring 34500Y/19920V to 120/240V step-down service.
Customizable Specifications:
kVA, primary voltage, secondary voltage, frequency, vector group / phasor, feed type, standard, accessories, destination port.
For utility distribution points, rural overhead distribution and outdoor single phase service connections, this transformer is suitable for projects requiring medium-voltage step-down power supply. The unit is a 100kVA single phase liquid filled pole mounted transformer configured for 34500Y/19920V to 120/240V voltage conversion.
Its ONAN self-cooled design, mineral oil non-PCB insulating fluid, copper winding, 200/30kV BIL rating, 5-position tap changer and live bushing lug arrangement help match project requirements for voltage, insulation level, installation method and terminal interface. Buyers can use these specifications for quotation, technical approval and project specification confirmation.
