ABILKEEN LB12-220 220kv Oil Immersed Current Transformer Price and Current Transformer Supplier
Product Overview
Our company offers customized 0.2S-class special-purpose transformers, meticulously tailored to meet diverse user requirements. These transformers feature dual protective winding components, namely steady-state and transient protection, ensuring reliable operation and safeguarding electrical systems against various faults.
The product is equipped with a durable stainless steel metal expander, providing enhanced protection and stability. The oil storage tank is designed with heat dissipation fins, which significantly improve heat dissipation efficiency. Leveraging the thermosiphon principle, the primary winding effectively promotes oil circulation within the transformer, facilitating efficient internal heat dissipation and maintaining optimal operating temperatures.
Specifically engineered for outdoor use, this type of transformer is suitable for deployment at altitudes below 2000 meters. It can operate stably in ambient temperatures ranging from -30℃ to +40℃, making it an ideal choice for a wide range of outdoor applications. Whether in harsh cold climates or high-temperature environments, our special-purpose transformers deliver consistent performance and reliability.
