Strict factory inspection.
Before delivery to customers, each UHV transformer undergoes a series of stringent factory tests to ensure product performance and safety.These tests include, but are not limited to:
insulation strength test
Tests without load loss
Short circuit test
temperature rise test
winding strain test
Oil spectral analysis
Comprehensive performance tests
Through these strict factory inspection procedures, we ensure that every UHV transformer meets stringent customer requirements and provides a reliable power supply upon delivery.
Contact our sales team and we will provide you with a custom solution for UHV transformers.
