Integrated Insulation Solutions for Global Transformer & GIS OEMs
EONOVA is dedicated to providing integrated electrical insulation solutions for global power equipment manufacturers. Our comprehensive portfolio encompasses transformer bushings, hollow composite insulators, porcelain hollow insulators, GIS insulation cylinders, operating rods, and high-voltage electrical testing equipment. Serving transformer, GIS, and instrument transformer OEMs worldwide, we safeguard the reliable operation of modern power grids and empower global electrification.
Share the equipment application, site altitude, temperature range, pollution duty, installation interfaces and acceptance requirements. Confirm suitability and test evidence against the offered model, manufacturing entity and project specification.
Driven by innovation and committed to delivering sustainable value for our customers, these core principles guide every engineering solution we deliver.
Review applicable standards, the manufacturing entity, inspection plans and available documents against the drawing and service duty. IEC 60137, IEC 61462 and IEC 62271-203 address different equipment scopes; model compliance depends on the relevant test evidence and project acceptance requirements.
