H61 Three Phase Distribution Transformer 10kV-30kV 100KVA Oil Immersed with IP54 Protection
The H61 oil-immersed three-phase distribution transformer is engineered for small to medium-power applications, operating at 10-30kV with capacities from 50-160kVA. Featuring an advanced oil-immersed cooling system that maintains temperature rise below 65K, this transformer utilizes high-permeability silicon steel sheets to reduce losses by 15%-20%. With IP54 protection rating and compact box design, it enables outdoor installation without requiring dedicated power distribution rooms.
