Product description


Product Description

The high-current transformer bushing adopts pure-porcelain structure.The unique shielding structure improves field intensity distribution of flange area and prevents partial discharge under power frequency pressure.The bushing are internaly connected with current transformer oil,effectively solving the problem of oil leakage,poor heat dissipation,high temperature rise,big volume and expensive cost which occurred in traditionally designed OIP bushing,Such creative design mentioned above enormously reduces the bushings of temperature rise,partial discharge,dielectric loss and maintenance effort,moreover supply characteristics as beautiful appearance,convenient installation,reliable performance.
At present,the bushing are mainly configured with copper conductor or aluminum conductor,in which the aluminum conductor is cheaper but with equal performance.
