15KVA Step Up Three Phase Dry Type Transformer 220V/380V 440V/480V
1. Feature
① Insulation material
Using high temperature resistant insulating paper as the insulating material, it has multiple properties of high temperature insulation, flame retardancy and moisture resistance.
②Terminal block
Lower capacity transformers used terminal block, with beautiful appearance, excellent pressure resistance, temperature resistance, and flame retardant performance. High-quality copper bars are used for high power.
③Iron feet
It mainly adopts CNC bending and cold-rolling plate, with multi-colored plating (golden), blue zinc (silver white), white zinc (ivory white), surface anodizing (black) and other environmentally friendly electroplating options.
