Product Description
Oil Immersed 3 PhaseTransformer
The fully sealed oil immersed power transformer adopts the fully oil-filled sealed type. The corrugated
tank shell is apermanently sealed tank with its elasticity adapting to the expansion of oil,can adapt to
a variety of outdoor harsh environment ,which has been widely used in various power distribution
equipment.
Product Features
- Low noise: compact design structure, application of new materials and new technology, reduce noise, no oil storage tank, lower height than similar products.
- Reliable long-term service life: The fully sealed power transformer case cover and the tank rim are bolted welded to isolate the contact between oil and air.
- Small size and beautiful appearance: oil transformer series of transformer oil tanks use corrugated plate fins. When the oil temperature changes, the change in oil volume is adjusted and compensated by the elastic expansion and contraction of the corrugated sheets. The corrugated fuel tank is beautiful in appearance and small in size, with a small footprint.
- Maintenance-free: Oil immersed Outdoor Distribution Transformer,the fully sealed transformer does not require maintenance.
When placing order, please provide the following technical parameters
