Large Distribution Transformers
Large distribution transformers
Large distribution transformers are used for receiving energy from higher voltage levels and to transform and distribute this energy to lower voltage substations or directly to large industrial consumers.
Transformers in this range are three-phase and can be manufactured with off-circuit tap changer or on-load tap changer. Transformers provided with on-load tap changer usually have a separate tap winding.
The core is constructed of grain-oriented steel laminations. The windings are made of either copper or aluminum conductor and wound in a foil or multi-layer configuration. The tank construction can be a corrugated fin wall type or of a rigid construction type with radiators typically used for larger transformer. Fans can also be mounted on the radiators to provide additional cooling capacity.
Medium Distribution Transformers
Medium distribution transformers
Medium distribution transformers are used to step down three-phase high voltage to low voltage for energy distribution, mainly in the countryside or low-density populated areas.
The transformers are three-phase, oil-immersed hermetically sealed, adaptable for pole-mounting or assembly in substations.
On request, the transformer can be equipped with an oil conservator and the transformer tanks surface can be hot dip zinc coating.
Single Phase Distribution Transformer
Single-phase distribution transformers
Range up to 315 kVA
ABB liquid-filled, single-phase distribution transformers are specifically designed for networks where it is not practical to have a three-phase supply.
They are typically used for servicing residential overhead distribution loads.
They are also suitable for light commercial loads, industrial lighting and diversified power applications.
Small Distribution Transformers
Small distribution transformers
Small distribution transformers are typically oil-immersed and suitable for pole-, pad- or ground-mounting. They represent an economical option for certain networks, particularly those with low population densities.
Depending upon requirements, transformers may be connected between two phases of a three-phase system (two high voltage bushings) or from one phase to ground (single high voltage bushing).
The units are suitable for residential overhead distribution loads, as well as light commercial or industrial loads and diversified power applications.
