Utilizing high-permeability silicon steel sheets and foil winding structure, the no-load loss is reduced by 30% compared to traditional models, and the load loss is reduced by 20%.
Using high-quality copper coils, with a partial discharge capacity of less than 10PC, the coils feature moisture and dust resistance, and mechanical strength that is industry-leading.
By using flame-retardant materials such as epoxy resin casting, the risk of insulating oil leakage is eliminated, effectively preventing fire and explosion accidents.
CLHT products are sold to 38 countries and regions worldwide. We have signed supply agreements with local power bureaus for three consecutive years, contributing our modest efforts to the construction of the national power grid.
