Lighting Transformer

Product Description

Lighting Transformers are designed to supply power to lighting equipments in a commercial / industrial / domestic unit. Its primary supply connected to higher voltage 3Ph source and secondary is to be connected to load. Lighting transformers serves as isolation between primary and secondary, it also restricts any high voltage spikes and EMF coming with the raw mains incoming power. Lighting Transformers are very useful when system neutral is not available or faulty i.e where incoming supply is 3 phase 3 n wire and lighting load is 220 Volt single phase. It also restricts short circuit current in the load and saves major accidents. Power House lighting transformers are made with CRGO laminations and Electrolytic copper super enameled winding wires. They are available for wide range of inputs out are in the range and in capacity from 1K VA to 100 KVA. Construction : Lighting Transformers are two winding transformers with both windings made of copper. Electrolytic grade super enameled wire with best insulations are used. Core material are CRGO Strip cores. Experienced hands with best machines for winding ensures best results with minimum size. Appropriate class of insulation materials are used. Transformers are impregnated in insulating varnish for long lasting performance. Input and output are terminated on Glass Epoxy board with proper size of terminals. For Lighting Transformers greater than 30 KVA, usually a separate M.S Enclosure with temperature indicator is provided as shown in the drawing..
