Non-Flammable :
The insulating materials will not self-ignite and are self- extinguishing
Efficient & Quiet :
Transformer have low losses and low sound level.
Environmentally Safe :
Units are non-polluting and require little maintenance.
Dielectric Integrity :
Transformer are free of partial discharge and withstand high Basic Impulse Levels.
High Short-Circuit Strength :
Units are resistant to short-circuit forces
Hermetically Sealed :
Transformer are impervious to humidity and most common industrial contaminants.
Low Installation Cost :
Transformer can be installed close to the load center without costly vaults, dikes and special ventilation.
Conserve Valuable Space :
Designs are compact and light weight.
