Dry-type transformers are only used indoors. If they are to be used outdoors, rainproof buildings need to be built. They have low loss, low noise, high short-circuit resistance, strong flame retardancy, fireproof, explosion-proof, pollution-free, high temperature resistance, good moisture resistance, and safe and reliable operation. They are widely used in important places such as urban power grids, high-rise buildings, business centers, theaters, hospitals, hotels, tunnels, subways, underground power stations, stations, docks, airports, combined substations, etc.

       Design Advantages of Dry-type Transformer       

1. The most advanced epoxy resin casting process in China is adopted, which has good insulation performance;

2. The new cold-pressed oriented silicon steel sheet is used as the iron core, and the seven-step 45-degree full-bevel joint has beautiful craftsmanship, and the no-load loss is reduced by 3-5% percentage points compared with the three-step;

3. In the traditional dry-type transformer production, the insulating paint of the iron core is mostly black or black, while TSTY uses transparent insulating paint, which can intuitively see the process and materials.

4. The core bending clamp is designed independently, with a simple structure, convenient manufacturing and installation, and greatly reduced operating noise.

High reliability: using advanced technology, high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, and a service life of 30 years.

Zero pollution operation and maintenance: Using epoxy resin cast insulation material to meet high fire and explosion requirements, especially suitable for densely populated or enclosed spaces; Oil-free cooling system, eliminating the risk of oil leakage, in line with environmental protection certification; Fully sealed structure to achieve maintenance-free design, the whole life cycle operation and maintenance costs reduced by 60% +.

Wide voltage range adaptation: Support 6.6kV to 35kV medium and high voltage grid access, covering industrial and commercial power distribution, rail transit, new energy grid connection and other scenarios.

Efficient heat dissipation and weather resistance: Natural air cooling (AN) or forced air cooling (AF) mode, combined with IP23 and above protection level, can withstand -40 ° C to + 120 ° C extreme environment, humid, dusty, corrosive gas environment can still operate stably.
