Furnace Transformers
Furnace Transformers uses high-quality silicon steel core and laminated by steps. It is advantageous in low loss; low noise, low voltage partial discharge and high anti short-circuit capacity. Coils are winded by high-quality oxygen-free copper wire as well as using pre-compressing brackets processes and interior and exterior structure, which guarantee the dynamical and thermal stability of the transformer. The transformer tank uses bending corrugated bell prover shell with nice appearance. The core is D shape yoke and 45 angle seaming. The core and oil box are well fixed and well protected on moving.
220KV Oil Immersed Power Transformer
Furnace Transformers
1. High-quality silicon steel core.
220KV power transformer uses high-quality silicon steel core and laminated by steps. The core is D shape yoke and 45 angle seaming. The core and oil box are well fixed and well protected on moving.
2. Advantages
It is advantageous in low loss; low noise, low voltage partial discharge and high anti short-circuit capacity.
3. High-quality Coil.
Coils are winded by high-quality oxygen-free copper wire as well as using pre-compressing brackets processes and interior and exterior structure, which guarantee the dynamical and thermal stability of the transformer.
4. Transformer Tank
The transformer tank uses bending corrugated bell prover shell with nice appearance.
