Jdc5-220.jdcf-220 (W1, W2, W3) voltage transformer
■ Executive Standards
The product performance meets the national standard GB1207 voltage transformer
■ product structure and performance characteristics
This type of voltage transformer is of cascade insulation structure. Its primary winding is divided into four windings. Each winding is an insulation grade. The primary potential gradually decreases from top to bottom. The upper end "a" is fully insulated and the lower end "n" is the grounding end. The iron core is equipotential connected with the primary winding
The whole body is supported by components made of high-quality insulating materials with low dielectric loss factor. After vacuum drying, the body is installed in a porcelain sleeve filled with transformer oil. The transformer oil is vacuum dehydrated, degassed and filtered.
