Product Detail

The 33kV/35kV voltage level is in the category of sub-transmission and high-voltage distribution. It is higher than the common 10kV/20kV distribution voltage and is usually used for higher power supply capacity and longer power supply distance. It is particularly suitable for supplying power to remote load centers, scattered towns, large industrial and mining enterprises, and wind farms/photovoltaic power stations. With its excellent safety and installation flexibility, the 35kv dry-type transformer has irreplaceable advantages in specific application scenarios.

Dry Transformer Advantages

1.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.

2.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% +.

3.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.

4.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.

Product Design Advantages

Advanced casting process

It adopts the most advanced epoxy resin casting process in China, with good insulation performance;

High-quality raw materials

It adopts the new cold-pressed oriented silicon steel sheet as the core, seven-step 45-degree full-bevel joints, beautiful process, and no-load loss is reduced by 3-5 percentage points compared with the three-step;

Transparent insulating paint

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

Bending clamps

The independently designed core bending clamps have simple structure, convenient manufacturing and installation, and greatly reduce operating noise.
