The main switch and the ground switch have mechanical interlocking functions.

The switch is operated by a dedicated operating handle, and the operation speed and strength of the contact are determined by the operating mechanism spring, and the change is changed due to the different operators. When the switch is hierarchically, the speed of the contact is rely on the speed and the arc gate to extinguish the arc, and the arc current is cut immediately.

The switch operation holes can be locked with a bright lock to prevent errors.

The switch main mechanism and grounding mechanism use spring storage operators, structural stability, less components, low failure rate, and significantly improved product reliability, and the mechanical life is as high as 10,000.

The key components use non-ferrous metal materials such as aluminum alloys. Other components use high-density carbon steel, treated by 8 steps, and finally baking highly attached outdoor military powder, ensuring institutional performance.

The mechanism interlock is directly fixed to the main body of the main mechanism and the ground mechanism, ensuring that the interlock indication is consistent with the actual position of the switch and prevents errors.

Electric operating mechanism: When a set of electric motors and attachments are installed on the basis of the original manual operating mechanism, it can be extended as an electric operating mechanism.

The switch adopts foreign technology. The key components use imported products, and the modular contacts are highly conductive and high-conducting tabs, the auxiliary silver process, so that their comprehensive conductive capacity is significantly improved, and the temperature rise is clearly smaller than the similar imported products.

Move, the static contacts are valid for 105mm, leading to the domestic leading, maximizing the insulation performance of the product under the zero table.

The FTU can be installed to realize the transient current speed, time-limited current speed, timing overcurrent, etc., and can remotely control the ring switch device.
