250 KVA 33KV To 11KV 3 Phase Step Down Oil Immersed Power Transformer

In 2017, 250 kva 3 phase oil-immersed transformers entered Nigeria. This 250 kva 3 phase transformer is designed to guarantee reliable power conversion and efficient operation of separation. 250 kva power transformer with 33kv to 11kv step-down for seamless voltage adjustment. To ensure optimum performance and service life, it features a durable oil-immersed design and advanced cooling mechanism. Step down transformer from 33kv to 11kv is designed to meet the requirements of modern complex power supplies. Its three-phase, oil immersed power transformer provides enhanced electrical isolation and security for your power system, providing a stable and efficient power supply.

• We use oxygen-free copper wire with lower resistivity, which undergoes a series of additional surface treatments to ensure a smoother surface with no burrs or sharp edges. This results in lower load losses and more reliable electrical performance for the transformer.
• High-quality silicon steel sheets are selected, with improved performance levels and lower specific losses, leading to reduced no-load losses in the transformer.
• We use high-grade laminated wood insulation that does not crack, even under short-circuit current conditions, maintaining its integrity.
• The transformer oil is deeply filtered, resulting in lower levels of moisture, gas, and impurities, which enhances the reliability of the transformer's operation.
• We use high-quality rubber sealing materials that are highly resistant to aging and prevent leakage.
• All raw materials undergo rigorous quality inspections, ensuring resistance to aging and prevention of leakage. All material suppliers are strictly audited according to national standards such as ISO9000.
