In fact, the current interior rj45 plug socket is the basis of circuit switching equipment , why do you say ? Because this is one of the first switch circuit device , as is currently the most high-voltage switches , disconnectors and load switch , its basic institutions are indoor wall switch evolved through the foundation springs , wire, connecting rods, metal sheets and other combinations gradually evolved into today's circuit panel, as well as more complex structures , we can say basic things are inseparable.rj45 plug with the power of the word and the current generation , making the cities are developing, the gradual emergence of an intelligent grid , and began to develop , and with building a smart grid and enhance the development of related technologies will continue to progress , high voltage switch will intelligent, fast development miniaturized , modular , and high reliability. We will seize this favorable period, according to changes in market demand , development and manufacture of products to meet market demand , improve product quality, to achieve full completion of the unified strong and smart grid contribute.
