る。Even if thermal elongation occurs in a container such as a gas insulated switchgear, it is absorbed by the flexibility of the corrugated bellows formed in a portion of the container, so there is no excessive local stress at the attachment point between the electrical tank and the pocket. Similarly, the flexibility of the corrugated bellows facilitates the installation of the connection between the electrical tank pocket and the gas insulated switchgear, eliminating leakage from the sealing surface.
