The bushings 2 of each phase are arranged so as to be shifted in the length direction of the connecting cable 3. On the other hand, the connection cable 3 has a terminal structure including a protection tube 4 fixed to the bushing portion 2 and an anticorrosion layer 5 formed over the protection tube 4 and the sheath of the cable. The anticorrosion layer 5 is formed by winding a self-fusing tape and a waterproof tape.

Since the electrical equipment such as the IS1 is downsized, the arrangement interval of the bushing portion 2 on the casing has to be reduced. However, when the interval between the bushing portions 2 is reduced, as shown in FIG. 3, the interval between the bushing portion 2 and the adjacent cable terminal is also reduced, so that taping work for forming the anticorrosion layer 5 becomes very difficult. There was a disadvantage.
