35kV Power Transformer for Grid Oil-Immersed Low Loss Energy Saving Distribution Substation CE CESI UL CNAS Certified

Product Overview

This 35kV Oil-Immersed Power Transformer for Grids is a high-efficiency, low-loss distribution transformer engineered for national and regional power grid networks, utility distribution substations, and renewable energy grid connection. Manufactured to S13/S15 energy efficiency standards — featuring ultra-low no-load losses — it significantly reduces grid power losses and operational energy costs compared to conventional distribution transformers. Built with grain-oriented cold-rolled silicon steel cores, high-purity copper windings, and a fully sealed oil tank, it delivers decades of reliable, maintenance-reduced performance in urban and rural distribution networks. Certified to CE, CESI, UL, CQC, and PCCC international standards, tested in a CNAS nationally accredited 8,000m² laboratory, and manufactured in a 30,000-unit/year Guangdong facility. Core strategic supplier to major state grid and power engineering corporations, with deployment across 60+ countries.
