Advantages of cast resin dry-type transformers

When researching the  advantages of cast resin dry-type transformers , you may find the information available to be somewhat incomplete. More so, only a few of its favourable features are well known, with one of the most noteworthy being its minimal fire risk due to zero oil usage. Self-extinguishing, low fire hazard: The transformer insulation consists of an epoxy resin and quartz powder mixture (an eco-friendly material). This allows the winding to be flame-retardant, self extinguishing and almost maintenance free, eliminating the need for costly fire extinguishing equipment. It will also not produce toxic gases, not even under the effects of arcing. Zero oil usage: The cast resin transformer only needs air to cool. Therefore, it eliminates extra costs and labour for liquid-level checking, oil testing, oil recycling costs, and dielectric testing for moisture absorption. Being almost maintenance free, there are no more on-site oil leaks, which require gasket replacements. Ec

Compact / Unitised / Packaged Sub-station (CCS/USS/PSS)

We manufacture various modules of Indoor/Outdoor type Compact Sub-Stations upto 2500 KVA capacity, 33KV class of transformers with HT/LT switchgears. The Compact Sub-Station (CSS) is also known as Unitised Sub-Station (USS) or Packaged Sub-Station (PSS). The Compact Sub-Staton is a compact arrangement, which replaces conventional sub-station arrangement consisting of Load Break Switch / Vacuum Circuit Breaker, Transformer, Distribution Panel, Lightening arresters mounted on a pole structure or on a platform. CSS is designed, keeping in mind the personal safety & aesthetics, considering HT equipment is located in high density urban places. It is a pre fabricated secondary sub-station consisting of three compartments (i.e.) H.V.Compartment which houses Vacuum Circuit Breaker (VCB) or Load Break Switch (LBS), the transformer compartment which houses dry type /oil cooled transformers & the LV compartment which houses ACB, MCCB, SFU etc. as per client's requirement. All comp
