PROBLEM TO BE SOLVED: To provide a switchgear by which assembly workability and production efficiency are improved and downsizing is attained, by assembling a single-pole vacuum switch tube to constitute a single-pole unit, and mounting the required number of the single-pole units on a truck frame, respectively. SOLUTION: The truck frame 1 holding an operating mechanism 3 which mechanically opens and closes the vacuum switch tube 7, and main conductors connected to the fixing side of the vacuum switch tube 7 and connected to a moving side through a flexible conductor 11, are fitted to a single-pole mounting plate 15, respectively, through insulating support insulators 18, 19. A plurality of the single-pole units 21 retaining the vacuum switch tubes 7 are included, then each single-pole mounting plate 15 of a plurality of the single-pole units 21 is mounted on the truck frame 1, respectively, and a plurality of the single-pole units 21 are installed on the truck frame 1.
