As a professional manufacturer in China, SGOB is committed to providing you with high-quality 300kva Three Phase Oil Immersed Transformers, which are designed with advanced technology to ensure efficient and reliable power distribution for various application scenarios. As a trusted manufacturer and supplier, we provide customized services to ensure that each product has high quality and good durability.
SGOB high quality 300kva Three Phase Oil Immersed Transformer safely and stably converts the high voltage of the grid to the low voltage required by your equipment. It is the core equipment for ensuring smooth power flow in daily operation.
High efficiency and low operating costs: We use high-performance cold-rolled silicon steel sheet iron core and high-quality oxygen-free copper wire winding to reduce no-load loss and load loss to a minimum. This means that over a long life cycle, the 300kva Three Phase Oil Immersed Transformer can provide you with significant savings in electricity bills, reduced energy waste, and a win-win situation for both economic and environmental benefits.
High environmental adaptability: oil-immersed design is its natural advantage. Insulating oil not only provides stable heat dissipation performance, but more importantly, it provides excellent insulation, moisture and dust protection for the internal core and coil like a layer of "protective armor". This allows our transformers to withstand moisture, salt spray and dust in environments such as outdoors and industrial areas, ensuring stable operation under harsh conditions and greatly reducing the risk of failure due to environmental factors.
Structural reinforcement for long-term stability: We have made several practical improvements to our proven traditional structure. For example, the design of spiral coil and longitudinal oil duct enhances the internal heat dissipation effect; the coil end is effectively supported to enhance the ability to resist short-circuit current impact; and the new hoisting and body positioning structure ensures that the internal structure remains stable after long-distance transportation. These details are all about one goal: delivering a durable device with a longer life and lower maintenance requirements.
