ABB transformers Manuals

This operating manual is intended to help you use the VCC dry-type transformer

The three phase padmounted distri bution tra n s fo rmer is designed to provide electrical service on underground distribu t i o n systems. The transformer is designed for outdoor mounting on a pad. Primary and secondary cables enter the transformer compartment from below, through openings in the p a d . All exposed live parts are completely enclosed in tamper-resistant cabinets with provisions for padlocking.

These instructions apply to liquid filled secondary unit substation transformers manufactured by the ABB Transformer Facility at Jefferson City, Missouri. Secondary Unit Substations are typically composed of three (3) major sections: the high or medium voltage section; transformer section; and low voltage section. These sections can be close coupled whereby the sections are bolted directly together to form a single line of electrical equipment or the sections can be separated by distance and

ABB is committed to developing all its products to meet ever-more-demanding environmental and effi ciency requirements. Our ultra-effi cient dry-type transformers have been greatly improved in terms of effi ciency, specifi cally tailored to the particular application identifi ed,for customers with a commitment to environmental protection and costawareness.

The transformer requires less care compared with other electrical equipment. The degree of maintenance and necessary inspection for its operation depends on its capacity, on the importance within electrical system, the place of installation within the system, on the weather conditions, and the general operating conditions.
