Running large and medium-capacity AC contactor huge number

Put into operation in large and medium-capacity AC contactor huge number, so the total annual energy consumption up amazing energy-saving technologies such contacts is to make contacts in the DC mode operation, so that not only save energy, but also  electric transformer  reduce noise and  electric meter , and can extend the life of AC contactor. AC contactor energy-saving technology with a very large economic and social benefits. Currently on the market already exists AC contactor saving  electri cenergy meter  a lot, but because of the problems have not been solved, leading to the promotion of energy-saving technologies surface is small, the penetration rate is not high. This thesis around the country AC contactor manufacturers and based on a survey of user needs.
