Features

The oil tank is equipped with 35kV 11 type oil-immersed step-up transformer, and the oil tank is fully sealed structure, the radiator is rationally laid, and the high-performance seals, pressure relieve valve, gas relay, oil level gauge, temperature controller are equipped. The advantages are low loss, low noise, low temperature rise, high resistance to short circuit, high overload, no leakage and so on. In addition, the high-voltage load switch and high-voltage fuses are also placed in the oil, the use of transformer oil as an insulating medium, which has a strong electrical performance.

In addition, high-voltage load switch and high-voltage fuses are also placed in the oil tank, the transformer oil is used as the insulating medium, which makes it has a strong electrical feature.

The high-voltage room is equipped with enhanced anti-contamination outlet bushing, at the end there set the fully insulated cable contacts, and the arrester is also equipped to reduce the over-voltage risk. The high-voltage room is also equipped with a sensor. Electromagnetic group and live display are employed to prevent misuse.

Low-voltage room is generally employed the dual-line as the incoming line, and equipped with circuit breaker, disconnector, current transformer, surge arrester and other components, another substation is used in it as a transformer for the entire substation power supply.

The three compartments are structurally independent and electrically interconnected. This not only ensures the safety and convenience of operations, but also ensures the safety and reliability of operations. The transformer box is designed to employ a unique labyrinth sealing type, coupled with high-performance long-life seals, all the incoming and out coming line and the vents are equipped with anti-dust chamber, which can effectively prevent dust, rain and snow. This product truly achieves full condition, full insulation, fully sealed, maintenance-free, which ensures that it can be used in the harsh environment for 20 years.
