DISCONNECTOR SZ 24 DISCONNECTOR 24KV

SZ24 disconnector is used to simplify operation in fault situations and to reduce recovery and maintenance time. SZ24 disconnector can be operated from the ground level or pole by using operating rods such as our CT60.50 and CT48.64. KG43 busbar connector can also be used instead of KG41.- Rated voltage (Ur): 24 kV- Power frequency withstand voltage: 1min, 50 Hz 60 kV - Lightning withstand voltage: 145 kV - Rated frequency: 50 Hz- Rated normal current (Ir): 400 A- Rated short time withstand current (Ik): 10 kA- Rated peak withstand current (Ip): 25 kA- Rated closed-loop breaking current (Iloop): 10 A- Rated mainly active load-breaking current (Iload): 10 A- Rated short-circuit making current (Ima): 25 kA- Rated earth fault breaking current (Ief1): 30 A- Rated cable- and line charging breaking current under earth fault (Ief2): 17,3 A- Rated cable-charging breaking current (Icc): 10 A- Rated line-charging breaking current (Ilc): 10 A- Rated duration of short circuit (tk): 1 s- Mechanical endurance class: M1, 1000 operating cycles- Capacitive switching class: C2- Leakage distance: minimum 628 mm- Ice breaking capacity: 10 mm- Minimum distance between phases after installation: 800 mm
