DK-25VA-10000VA

BK(JBK) A single-phase transformer converts voltage in single-phase AC circuits using two coils around a shared magnetic core. It’s used in residential, commercial, and industrial settings where three-phase power isn’t needed. Installed outdoors or in substations, they vary in size and voltage ratings from a few kVA to several hundred kVA, crucial for adjusting voltage levels to power electrical equipment safely and efficiently.

Materials:

1. Iron core

The use of high-quality new cold to oriented high silicon silicon steel sheet stacked, adding silicon to the steel sheet can reduce the conductivity of the steel sheet, increase the positive rate, it can reduce eddy current, reduce its loss, the quality of the transformer used in the quality of the silicon steel sheet has a great relationship;

2. Wire

Using PEW, UEW, BIW, SEIW, FEAI light covered wire and glass wire, the transformer for the wire requirements are good conductivity, the coating layer has enough heat resistance, and to have a certain corrosion resistance, the most commonly used temperature grade F enameled wire.

3, insulation materials

The high temperature resistant insulating paper is used as the insulating material, with high temperature insulation, flame retardant and moisture resistance.

4. Terminal block

Small power using terminal block, beautiful appearance, excellent pressure, temperature resistance, flame retardant performance. High power adopts high quality copper bar.

5. Iron feet

Using CNC bending cold binding plate, there are colorful plating (golden), blue zinc (silver), zinc (ivory), surface anodized “black” and other environmental protection plating options.
