- Corrugated sheet or plate radiator oil tank, beautiful appearance.
- New hanger plate structure, solving the problem of body “suspension”.
- The transformer oil does not contact with air, so regular oil sample test (sealing type) is not necessary.
- Equipped with self-locking nuts, no-suspended core structure, close fitting of body and oil tank; it can bear movement vibration and joint.
- Corrugated sheet not only has cooling function, but also has “breathing” function. Tts elasticity can compensate the oil volume change caused by temperature change.
- No oil needs to be changed in the normal service life, improving the safety and reliability of power grid operation.
