Product information

Product features:

1. The internal iron core is made of high quality, high silicon silicon steel sheet, and the main materials are selected with the most suitable high permeability and low loss materials to meet customer requirements and use conditions, and the transformer performance is designed to be in a better state. 2. The internal insulation material is made of high-quality environmental protection composite material, which has multiple properties of high temperature insulation, flame retardant and moisture resistance; Class B, Class F, class H insulation materials can also be selected according to customer requirements. 3. Reasonable design, low voltage variation rate, long-term rated use. 4. Beautiful appearance, small footprint, movable, easy to install. 5. Panel voltmeter display is accurate and easy to read. 6. A variety of models, specifications, capacity, voltage to choose from.
