Low Price High Quality DIN Transformer Bushing

Transformer bushings play a critical role in electrical power systems, providing insulation and support for conductors within transformers. The production process of German standard transformer bushings involves several meticulous steps to ensure quality and reliability. Below is an overview of the typical production process:

Raw Material Selection: The process begins with the careful selection of high-quality raw materials. Insulating materials such as porcelain or composite materials are chosen for their excellent electrical and mechanical properties.

Mixing and Preparation: If porcelain is used, the raw materials undergo mixing to achieve the desired composition. This mixture is then shaped into the required forms using molds. For composite materials, a similar process of mixing and molding is employed.

Forming and Shaping: The formed material is subjected to high-pressure molding or extrusion processes to give it the desired shape and dimensions. This step is crucial for achieving uniformity and precision in the final product.

Drying and Curing: The shaped bushing components undergo a carefully controlled drying process to remove any moisture. Depending on the material used, curing may also be required to enhance mechanical strength and electrical properties.

Glazing and Finishing: Porcelain bushings are often glazed to improve their surface properties, such as smoothness and resistance to environmental factors. Additionally, finishing touches such as trimming and polishing are carried out to ensure the bushings meet aesthetic and functional standards.

Assembly and Fitting: Once the individual components are ready, they are assembled according to the specific design requirements. This may involve fitting metal fittings, such as flanges and terminals, to the bushing body.

Testing and Quality Control: Before the bushings are shipped for installation, they undergo rigorous testing to verify their electrical insulation, mechanical strength, and dimensional accuracy. Various tests, including partial discharge testing, impulse voltage testing, and dimensional inspections, are conducted to ensure compliance with German standards and customer specifications.

Packaging and Shipping: Finally, the finished bushings are carefully packaged to prevent damage during transit and storage. Proper labeling and documentation are provided to facilitate easy identification and traceability.
