OLTC Distribution Transformer

We are an association known for making amazing OLTC Distribution Transformer. Worked by utilizing predominant quality crude materials and under the supervision of gifted and experienced staff, our open air high voltage transformers offer higher perseverance and proficiency levels. Accompanies Cooling tubes, radiators, and layered tanks and made to Pole mounted or ground mounted. Gives Free breathing or hermetically fixed CSP and Non-CSP Winding-copper/aluminum (thwart/rectangular wire/ground wire) with Fittings and frill, link. These Transformers are intended for a most extreme temperature rise 40/50ºC of oil and winding and Lower temperature rise can be offered on ask. Inferable from our enhanced involvement in making transformers, our transformers are high sought after among different residential and global markets.
