Product Description
The commonly used types of bushings for transformers include pure ceramic bushings, oil filled bushings, and capacitive bushings. (1) Pure porcelain casing. The surface electric field of the sleeve is relatively concentrated near the flange and end cover. The smaller the diameter of the sleeve, the higher the electric field intensity near the flange. This type of sleeve is mainly used for voltage levels of 35kV and below. (2) Oil filled casing. The bushing that uses the insulation barrier formed by transformer oil and insulation paper cylinder as the main insulation and does not use porcelain bushing as the main insulation is called oil filled bushing. Generally, this type of bushing is mainly used for voltage levels of 63kV and below. (3) Capacitive bushing. Due to its excellent performance and small overall size, it can correspondingly reduce the volume of transformers and greatly reduce costs, so it is widely adopted.
