The main venue of the 2020 CCTV Mid Autumn Festival Gala has selected "TNNPI Brand Dry Transformer" as the high-quality power supply, which will broadcast the gala to the world!
3. Energy conservation and environmental protection: steel, iron and other materials are easy to recover after the end of product life; All NOMEX paper used will not release toxic substances when burning; Other insulating materials can be degraded without polluting the environment; Low loss and energy saving of products; Low noise, flexible design.
Because dry-type transformer has no oil, there is no fire, explosion, pollution and other problems, so electrical codes and regulations do not require dry-type transformer to be placed in a separate room. The loss and noise have been reduced to a new level, creating conditions for the transformer and low-voltage panel to be placed in the same distribution room.

2. High reliability: NOMEX insulation material is selected for high and low voltage coils, and Class H solvent-free impregnating paint is impregnated by VPI vacuum pressurizing equipment for many times, and the coils are baked and cured at high temperature for many times. The product is Class H (180 ℃), while the main insulation material is Class C (220 ℃), with strong overload capacity and good short-circuit resistance. Under the condition of good ventilation, 20% overload operation is allowed.
