In high-voltage and extra-high-voltage (EHV) systems, insulation failures can pose serious operational and safety risks. That’s why high-quality, Localized OIP Bushings Upto 245 kV, are vital to ensuring performance, safety, and longevity in power transmission and distribution systems. These bushings serve as an essential interface between energized conductors and grounded transformer tanks or switchgear enclosures, offering both mechanical support and insulation in demanding environments.
At ECS Industries Pvt Ltd (Epoxy House) we specialize in the design and manufacture of high-performance Oil-Impregnated Paper (OIP) Bushings made in India to meet global requirements. Built to meet international standards and tested in NABL-accredited laboratories, our bushings are trusted by OEMs, utilities and infrastructure projects nationwide.
