Gas-insulated load disconnectors are designed for switching three-phase alternating current circuits with frequency 50 Hz, rated voltage 6-10 kV and rated current up to 630 A with insulated or earthed neutral through a resistor or arc suppression reactor. Gas-insulated switch-disconnectors are designed for switching without load of three-phase alternating current circuits with frequency 50 Hz, rated voltage 6-10 kV, rated current up to 1250 A, as well as to ensure the safety of work during the operation of electrical installations.
