High Insulation Resistant Isolation Transformer contains two windings: primary and secondary, that are separated from each other but wound on the same iron core. The Isolation Transformer isolates the equipment from noisy power line and reduces power line noise, surges, spikes and transients. The Isolation Transformer provides the complete electromagnetic and electro static shielding. High Insulation Resistant Isolation Transformer is strong and rigid in construction and requires minimal maintenance.
