Product details
summary:
GN19-12 Indoor High Voltage Isolation Relationship High Voltage Switchgear, used in power systems with rated voltage of 12KV, AC 50Hz and below, equipped with CS6-1 manual operating mechanism, used for opening and closing circuits under voltage and no load conditions. It also has derivative products such as anti fouling type, high prototype type, and installation of live display devices.
This series of isolating switches is equipped with CS6-1 manual operating mechanism (isolating switches with panels come with built-in integrated operating mechanism).
This series of isolating switches is of three types, consisting of a chassis, a shaft, a lever, a porcelain pillar insulator, a switch blade, and a terminal block. The rotating shaft is mounted on the chassis and has three pairs of levers welded on it. The levers are connected to a ceramic insulator and a knife chain through a pull rod. The rotating shaft extends out of the chassis, and any section of it can be connected to the operating mechanism.
Type C is a through wall type. Where C1 represents rotation on the through wall side; C2 represents the disconnection on the through wall side; C3 indicates that both sides are on the through wall side.
