Product Description

40KVA Hospital/Hotel Three Phase Dry Type Transformer 550V 433V 50/60Hz



1. Feature


1. Scientific and reasonable design, the voltage variation rate is controlled within 1~1.5%.

2. It is made of high-quality brand-new silicon steel sheet, which can effectively reduce iron loss and increase rate.

3. It is made of high-quality wire with high temperature resistance, its own loss is reduced to low, and the efficiency is greatly improved.

4. The use of H-class insulation and high-temperature-resistant insulation materials improves the high-voltage strength, insulation level and prolongs the service life.
