Products Description
Bushing insulator for oil-immersed transformer is a critical insulation and current-conducting component, designed to safely pass high-voltage conductors through the transformer tank while maintaining electrical insulation and oil sealing.
Our transformer bushings are manufactured to provide excellent electrical insulation, mechanical strength and long-term oil-tight performance, ensuring safe and stable operation under high voltage and harsh outdoor conditions.

Bushing Insulator for oil Transformer Widely used in:
Oil-immersed power transformers
Distribution transformers
Substation transformers
Transformer repair & replacement projects
