DIN Transformer Bushing

Transformer bushing is the main insulation device, which is divided into national standard, European standard (EN), American standard (ANSI), German standard (DIN), etc. according to the standards of different countries. It also has different models according to different voltages and currents. Transformer bushing is an insulation bushing that leads the high and low voltage leads inside the transformer to the outside of the oil tank. It not only serves as a ground insulation for the leads, but also serves as a fixed lead. The transformer bushing is one of the current carrying components of the transformer. During the operation of the transformer, it passes through the load current for a long time. When a short circuit occurs outside the transformer, it passes through the short-circuit current.

The sleeve is mainly composed of a capacitor core, oil conservator, flange, and upper and lower porcelain sleeves. The main insulation is the capacitor core, which is composed of concentric capacitors connected in series and enclosed in a sealed container composed of upper and lower porcelain sleeves, oil conservator, flange, and base. The container is filled with processed transformer oil, making the internal main insulation an oil paper structure. The contact surface between the main components of the casing is lined with oil resistant rubber gaskets. Each component is fully sealed inside the casing by the central clamping force applied by a set of strong springs installed in the oil storage tank. These sleeves come in various designs and can be customized according to customer requirements to meet almost any type of customer requirement.
