DIN 42530 Transformer Bushing Assembly - Oil Type LV Insulator with 70-150mm Dimensions and 0.10-1.40kg Weight Range
High-quality oil-type transformer low voltage bushing assembly designed for reliable electrical insulation and conductor support in transformer applications.
This combined insulator features a ceramic body and metal fittings permanently bonded using high-temperature resistant cement. The ceramic surfaces are specially treated with knurling or sanding for optimal adhesion, while an elastic layer and buffer system between ceramic and metal components prevent loosening under thermal stress.
