Descriptions
35kV oil-immersed on-load regulating transformer is a type of transformer used in power systems, usually in substations or user stations, to regulate voltage.
Model Description
Product Characteristics
- Low loss, significant energy saving: the use of high purity oxygen-free copper coil, reduce copper consumption, improve efficiency.
- Novel structure: The core adopts high-quality cold-rolled silicon steel sheet, full inclined joint, no punching, no stacking iron wheel process, effectively reducing no-load loss, no-load current and noise.
- Strong short-circuit resistance: the inner winding support is strengthened to improve stability and prevent instability deformation, especially for products with large capacity, the internal and external coils use a unified overall plate and pressure plate to improve the transformer's ability to resist sudden short circuit.
- High mechanical strength: the plate clamp and the side beam form a solid frame structure, the body and the tank six sides of the steel positioning, to ensure that it is not easy to displace during transportation.
- Good heat dissipation performance: The oil tank of 35kV oil-immersed on-load regulating transformer adopts the whole steel plate folded into a corrugated structure, increasing the mechanical strength and heat dissipation area, and improving the heat dissipation effect.
- Environmental protection, flame retardant, explosion-proof, maintenance-free: The tank seal structure is specially processed to ensure no oil leakage and has environmental protection characteristics.
- Small size, light weight: easy to transport products, the body and the fuel tank have a firm positioning structure, to maintain long-term stable operation.

Applications
35kV oil-immersed on-load regulating transformer has on-load voltage regulation, which means that it can adjust the output voltage under load conditions to adapt to changes in grid demand. This kind of transformer is widely used in commercial buildings, high-rise buildings, airports, industrial and mining enterprises, power plants, oil platforms, subways and tunnels and other important places with special fire protection requirements.
