What are the transformer bushings?
I'm talking about plastic, and that's what you say, BMC, SMC, DMC resin. Oil immersed transformers are generally ceramic bushings, because the physical and chemical properties of ceramics are very stable. BMC, SMC, and DMC resins are new materials and it is unclear whether any physical and chemical changes will occur in a prolonged oil immersion environment, and no one is likely to risk using them at the moment. Besides, ceramics are cheap too. At present, the dry type transformer bushing (insulator), through wall bushing, busbar support insulator and so on, generally do not use the ceramic. Because of ceramics, heavy, brittle and other reasons.
Oil immersed transformer bushings are generally ceramic, in order to stability of the ceramic bar. I said the plastic, it is estimated that you say BMC, SMC, DMC resin bar! These new things are generally seen in some dry-type transformers, bushings (insulators), busbars, insulators and general switches, bushings, and some through wall bushings. Oil immersed transformers are estimated to be afraid of their physical and chemical changes during long periods of oil immersion.
It's usually made of ceramics, but there are very few plastics, and occasionally there are silicone ones
