Dry Type Transformers

Fire resistant Cast resin transformers are well suited for installation in high-rise buildings, hospitals, underground tunnels, school, steel factories, chemical plants and places where fire safety is a great concern.

Hazard free to the environment, cast resin transformers have over the years proven to be highly reliable.

Distribution Transformers

General purpose distribution transformers are rated for 600 volts and below. They are generally used for supplying appliance, lighting, motorized machine and power loads from electrical distribution systems. They are either ventilated or totally enclosed, and are available with either aluminum or copper windings in standard ratings from 50 VA up to 750 kVA. Shielded distribution transformers are also available, which provide a copper electrostatic shield between the primary and secondary windings. The shield is grounded and thus shunts most noise and transients to the ground path rather than passing them through to the secondary.

Power Transformers

Power Transformers convert power-level voltages from one level or phase configuration to another. They can include features for electrical isolation, power distribution and control and instrumentation applications. Power Transformers can be configured as either a single-phase primary configuration or a three-phase configuration.
