Substation distribution transformers have cover-mounted, primary and secondary bushings and can be provided with load tap changers (LTC). They are generally connected directly to overhead utility power lines.
Unit substation distribution transformers are generally close coupled to switchgear, motor control, bus duct, or another type of incoming and outgoing equipment.
Hitachi Energy's proven design offers excellent mechanical strength that has been proven through years of service and special testing. Hitachi Energy uses a low-frequency heating insulation drying process where the insulation is dried in its own tank and is never exposed to the atmosphere once it dries.
