Product description
Parameters

  Wind power is an important form of wind energy utilization. Wind energy is a renewable, pollution-free, high-energy, and promising energy source. Wind power technology and equipment are an important part of the wind power industry, as well as the foundation and guarantee for the development of the wind power industry. The wind variable outer sleeve has become one of the important development products of all companies at home and abroad. This product has high electrical performance requirements. It can run at 80℃ in transformer oil for a long time, and it must be able to withstand a pressure of 0.6Mpa without air leakage.
