The three phase oil immersed power transformer uses mineral oil as both insulation and cooling medium. Through a carefully designed oil circulation system, the transformer achieves efficient heat dissipation and can handle large-capacity power transmission demands.

The three phase balanced design improves the efficiency of power conversion and also ensures the stability of system operation. These features make the transformer particularly suitable for large and medium-sized industrial projects and urban power grid construction.

The insulating properties of oil provide reliable protection for internal components, effectively removing the safety hazards posed by high voltages. In the meantime, the oil immersed design slows down the aging process of insulating materials, thereby greatly extending the transformer's service life.

Components-High Voltage Bushing, Low Voltage Bushing, Oil Conservator

The three phase oil immersed power transformer utilizes high-quality cold-rolled silicon steel sheets for its core. Combined with optimized winding designs, the transformer keeps no-load and load losses at relatively low levels.

A complete cooling system, through natural convection or forced oil circulation, ensures that the transformer maintains appropriate operating temperatures under different load conditions.

The sturdy steel plate welded oil tank not only provides reliable mechanical protection, but also demonstrates excellent seismic resistance. Consequently, the transformer can adapt to various complex environments.

The built-in protection devices, such as gas relay, pressure relief valve and temperature monitoring system, offer comprehensive safeguards for the transformer's operation.

Protection Devices Gas Relay, Pressure Relief Valve, Oil Level Gauge, Oil Temperature Controller

The protection grade of the three phase oil immersed power transformer typically reaches IP55 or above, which effectively resisting environmental factors like moisture and dust. Besides, a wide range of operating temperature (-25℃ to +40℃) enables the transformer to be deployed in most countries and regions.

From an economic perspective, although the initial investment for the transformer is moderate, its low operating and maintenance costs, coupled with a service life of 30+ years, result in superior overall economic benefits.
