Using high permeability silicon steel sheets and a cylindrical structure with copper foil wrapped around the shaft, the no-load loss is reduced by 30% compared to traditional models, and the load loss is reduced by 20%.
Adopting high-purity oxygen free copper wire coils, with a local discharge capacity of less than 10PC, the coils have moisture-proof and dust-proof characteristics, and the mechanical strength reaches the industry-leading level.
Choose high-quality insulating oil and use vacuum oil filtration and oil injection processes for better insulation and stronger short-circuit resistance.
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.
