Description

Overview

As a pioneer in China's power transformer industry, we have specialized in the R&D and manufacturing of power transformer equipment for decades, and established industry standards with core technologies.

  • Premium Durability: Superior insulation and mechanical resilience allow for extended system life and overall system reliability.reducing the frequency of outages. 

  • Certified Quality: Oil-immersed power transformers are manufactured, tested and delivered in our accordance with all applicable standards (ANSI, IEEE) maintaining US compliance which simplifies service and retrofitting.

  • Energy Efficient: Designed to accommodate heavier base loading for extended periods of time with low energy loss and minimal partial discharge for optimized energy savings.

This power transformer is fully compliant with international standards including IEC 60076-1, IEEE C57.12.00, ANSI C57.12.90, AS/NZS 60076.5 and EN 61558-1. It meets quality requirements and is widely adaptable to the operational needs of power grids in multiple overseas regions.

The voltage classes of some of these Power Transformer include 6kV, 6.3kV, 6.6kV, 6.9kV, 7.2kV, 10kV, 10.5kV, 11kV, 11.5kV, 12kV, 13.2kV, 13.8kV, 14.5kV, 14.4kV, 15kV, 15.5kV, 15.6kV, 17.5kV, 20kV, 21.9kV, 22kV, 24kV, 30kV, 33kV, 33.5kV, 34.5kV, 35kV, 36kV, 38kV, 38.5kV, 40.5kV, 44kV, 45kV, 46kV, 66kV  69kV.72.5kV 88kV 110kV 115kV 123kV 125kV 126kV 132kV 138kV 145kV 150kV 154kV 161kV 170kV  220kV 225kV 230kV 245kV 275kV 330kV 345kV 363kV 380kV 400kV 500kV Power transformers of voltage ,and aboveand customization is available.
