Product Description:
The dry type transformers in this series are used to directly step down the 35kV power supply from the grid to a 400V distribution power supply for users. This reduces the need for a 10kV substation, resulting in significant cost savings and a reduction in the construction of multi-level substations. It offers remarkable social benefits. The product achieves this by optimizing the high voltage coil structure, improving the distribution of interlayer voltage and capacitance. This greatly enhances the product’s ability to withstand atmospheric and operational overvoltage shocks. Additionally, it improves the distribution of electric fields, further reducing partial discharge levels.
Features:
1.Low operating costs
2.Safe, flame retardant, and pollution-free
3.Excellent moisture resistance, capable of operating normally under 100% humidity
