摘要： In a switch gear, such as a high-voltage enclosed switchboard and a vacuum load-break switch, of the type wherein items of electrical equipment including disconnecting devices and circuit-breaking devices are installed within a case, masses of a silicone gel are filled in compartments accommodating the electrical equipment instead of the sulfur hexafluoride used heretofore. An air space is left above the silicone gel in each compartment. This construction enables the provision of a safer switch gear of smaller size than heretofore.

摘要： A metalclad switchgear has three assemblies which are separately arranged in separate housings for housing a circuit breaker, a control line and a cable, all constituting the metalclad switchgear and which can be detachably coupled. The three assemblies are a circuit interrupting device, which can be designed for standardization, and a control line compartment and a cable compartment both of which can be designed in accordance with given specifications.
