Our journey began in 1983 when our Director, Mr. S.V. Gopalen, established the company with a factory based in Chennai, India. His industry experience dates back to 1967 when he started manufacturing Epoxy Castings and Fiberglass Tubes for the Switchgear and Transformer Industries. We at OLG indigenously Designed and Tested, the First External Flange Mounting ONLOAD TAP CHANGER as per IEC 60214 in Nov 1982. This OLTC used superior insulation like Epoxy Casting and Fiberglass-Epoxy Tubes instead of Phenolic bonded Paper material. In addition, OLG’s design of OLTC incorporated the Coarse-fine selector/ Reverser, which was also a first in Externally Mounted OLTCs. This helped reduce the oil quantity to less than 400 litres, rendering an OLTC much more compact than the existing designs.
