Standard type transformer are well suited for serving both industrial and commercial applications: the small, compact design saves value space and lighter weight makes handling and installation easier and less expensive. In addition to the standard type a variety of options are available to meet your specific requirements. transformers are designed for continuous operation, self- cooled for tropical climates, and are suitable for indoor and outdoor installation.
STANDARD FEATURES:
High Reliability and Easy Maintenance:
Distribution transformers can be manufactured with simple structure and having compact size, and yet they are mechanically strong and easy to inspect. The self-cooled or ONAN type system requires no auxiliary devices and permits easy maintenance.
Well Insulated Against Lighting Surge:
The coil is wound with untreated kraft paper, and the lack of varnish treatment allows the coil to be amply impregnated with degassed oil, which gives it high impulse voltage. Coils of high voltage have multi-layer windings, which minimize internal potential oscillation and electrical stress.
Cold-Rolled Grain-Oriented Silicon Steel:
Cold-rolled grain oriented sheet steel is used in the core, resulting in highly efficient transformer of reduced size and weight.
Mineral Oil:
The transformer is vacuumed and filled with high quality refined mineral oil having excellent insulating property that complies with IEC-296.
