The socket body has a hollow housing, and a four-phase power connective head is disposed at an end of the housing in order to supply power to the extension cord. A breaker having safety switch function and at least two power sockets providing voltages with different phases are disposed in the housing. An end of the conductive cable is electrically connectable with a four-phase power source. The other end of the conductive cable has a four-phase power plug electrically connectable with the four-phase power connective head of the socket body. The polyphase circuit includes three phase conductors, a neutral conductor and a ground conductor. The conductors are used to electrically connect with the four-phase power connective head, the breaker and the respective at least two power sockets."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Extension cord for polyphase voltage conversion","description":"An extension cord for polyphase voltage conversion includes a socket body, a conductive cable and a polyphase circuit disposed in the socket body.
