GU59/POT59 Automated transformer bobbin ，Chemical-resistant self-extinguishing, wide application: It can withstand various chemical media such as oil and flux that may come into contact with transformers during operation, and has self-extinguishing properties. In the event of an unexpected fire, it can delay the combustion and is suitable for multiple fields such as industry, home appliances, and new energy, expanding the application range of customers' products.

Motor-driven transformer GU/POT33 transformer bobbin，This product is made of high-temperature resistant materials. The phenolic resin skeleton can withstand temperatures of 150-200℃ in the air for a long time. After modification, the short-term temperature resistance exceeds 300℃, far exceeding the 130℃ upper limit of ordinary nylon (PA66). It is suitable for the heat dissipation requirements of GT33 transformers under high loads. Its coefficient of thermal expansion matches that of ferrite cores, which can prevent structural deformation caused by temperature fluctuations.
