Distribution Transformers

Transformers are tailer-made products and the deisgn varies with the impedence levels (constant Ohmic and constant percentage), transmission voltage and cooling requirments. These are normally provided with on load tap changer for voltage variations. For long distance ruler power distribution lines, speacial autotransformers with automatic tap changing equipments are inserted as voltage regulations, so that customers at the far end of the line receive the same average voltage as those closer to the source. The variable ratio of the autotransformers compensates for the voltage drop along the line.

NUCON's corrugated tank distribution transformers are compact in size and elegant in apperance. These transformers are manufactured imploying the most modern and reliable manufacturing practices. The role of fins is to increase the surface of the tank, which is in contact with the cooling air. Due to the temprature rise of the winding under load, the oil temperator also rises. The hot oil level rises and meets the top further goes down into the fins. Where it is cooled by the air rising up betwen the fins.

Three phase pole mounted transformers used extensively in rural distribution networks. The simple tank design used very low loss types requiring less radiator surface. corrugated fins are used to provide radiator surface for the larger ratings. The design and construction methods ensure that the mass is kept to a minimum for any given rating and loss level. This means that installation costs and pole loadings are also minimized. The HV outdoor shedded bushings for IEC types are located on the tank cover. LV bushings may also be on the tank cover or alternativly on the tank side. Arcing horns or lightining arresters can be fitted as required.

NSPL began operation over 30 years ago with supply to electricity boards. Today we offer a wide range of conventional distribution transformers globally. We provide reliable design excellent material and globally benchmarked manufacturing practises. Our transformers are used in industries such as power utilities, process indutries, railways, mines and other industries. Our products are designed on the latest simulation techniques and exhibit a fully type tested range. 2.5 MVA.

Amorphous metal distribution transformers are seen as the future product in energy efficiency programs and are currently introduced in many countries throughout the world. These transformers are equipped with amorphous metal cores, and produced only a fraction of the no-load losses to conventional magnetic steel cores. NUCON has been manufacturing these transformers since the early nineties. Recent testing on units which have been in service for ever 12 years, show that the no-load losses have been consistant since the unit were first put into service.
