GN19-12 HIGH VOLTAGE DISCONNECTING SWITCH

Short Description:

GN19-12 t ype indoor high-voltage disconnecting high-voltage switchgear, used in power systems with rated voltage 12KV, AC 50Hz and below, equipped with CS6-1 type manual operating mechanism, as a voltage and no load condition, the distribution , For the purpose of circuit integration, there are also anti- pollution derivatives, high prototypes, and additional live display devices.The disconnecting switch of this series is equipped with CS6-1 type manual operating mechanism (the disconnecting switch with panel has its own integrated operating mechanism). This series of disconnecting switches is three-pole type, consisting of a base frame, a rotating shaft, a lever, a porcelain post insulator, a knife and a wiring board. The rotating shaft is arranged on the bottom frame , on which three pairs of levers are welded, and the levers pass through the pull rod porcelain insulators and the knife necklace.The rotating shaft extends out of the base frame, and any section of it can be connected with the operating mechanism. Type C is through the wall. C1 means that the rotation is on the side of the wall; C2 means that the breaking is on the side of the wall; C3 means that both sides are on the side of the wall.

Product Overview
GN19-12 t ype indoor high-voltage disconnecting high-voltage switchgear, used in power systems with rated voltage 12KV, AC 50Hz and below, equipped with CS6-1 type manual operating mechanism, as a voltage and no load condition, the distribution , For the purpose of circuit integration, there are also anti- pollution derivatives, high prototypes, and additional live display devices.

The disconnecting switch of this series is equipped with CS6-1 type manual operating mechanism (the disconnecting switch with panel has its own integrated operating mechanism). This series of disconnecting switches is three-pole type, consisting of a base frame, a rotating shaft, a lever, a porcelain post insulator, a knife and a wiring board. The rotating shaft is arranged on the bottom frame , on which three pairs of levers are welded, and the levers pass through the pull rod porcelain insulators and the knife necklace.

The rotating shaft extends out of the base frame, and any section of it can be connected with the operating mechanism. Type C is through the wall. C1 means that the rotation is on the side of the wall; C2 means that the breaking is on the side of the wall; C3 means that both sides are on the side of the wall.
