Product features
High efficiency and energy saving: It adopts a three-dimensional rolled core structure with even magnetic circuit distribution, which reduces the joint loss of the traditional laminated core. The no-load loss and load loss are significantly reduced. The energy efficiency level reaches S20 standard and above, and the energy saving effect is obvious.
Low-noise operation: The three-dimensional rolled iron core has fewer seams and small magnetic resistance. The vibration and noise are greatly reduced during operation. It is suitable for noise-sensitive environments, such as residential areas, hospitals and schools.
Oil-immersed cooling: Using mineral oil as the cooling and insulating medium, it has excellent heat dissipation performance and can effectively reduce the operating temperature of the transformer. It is suitable for long-term high-load operation and extends the life of the equipment.
High reliability: optimized insulation and heat dissipation design, strong short-circuit resistance, stable and reliable operation, adaptable to various complex working conditions, and reduced failure rate.
Environmentally friendly design: using environmentally friendly materials and processes, complying with green manufacturing standards, reducing the impact on the environment, and meeting the environmental protection requirements of modern power systems.
Compact structure: The three-dimensional rolled iron core design makes the transformer small and light, easy to transport and install, saving space, and is especially suitable for places with limited space.
Easy maintenance: The oil-immersed design facilitates internal inspection and maintenance, reduces operation and maintenance costs, and extends the service life of the transformer.
Strong short-circuit resistance: the three-dimensional wound iron core has a solid structure and reasonable winding design, which can withstand large short-circuit current impacts and ensure safe operation of the equipment.
Low temperature rise: Oil-immersed cooling and the optimized design of the three-dimensional wound core make the temperature rise lower when the transformer is running, improving the reliability and life of the equipment.
Strong adaptability: It can adapt to various complex environments and working conditions, such as high temperature, high humidity, high altitude, etc., and is widely used in power systems, industrial and mining enterprises, urban power grids, rural power grids and other scenarios.
Good economy: Although the initial investment is high, due to its high efficiency, energy saving and low maintenance costs, the long-term operation economy is significant and the overall cost is low.
Intelligent optional: can integrate intelligent monitoring system to monitor current, voltage, temperature and other parameters in real time, support remote control and fault diagnosis, and improve operation and maintenance efficiency.
