Purpose:The GCD system is suitable for power plants, metallurgical steel rolling, petrochemicals, miners, machinery, textile and other industrial and mining enterprises, as well as high-rise buildings. It is used for distribution and centralized control of electric motors in three-phase AC power systems with rated voltage of 380-660V and frequency of 50Hz.

Structural features:
The cabinet of the device adopts a closed structure, and the skeleton is composed of special-shaped cold-formed steel, which has high mechanical strength. The frame and components are connected by screws to avoid welding deformation and stress.
2. Each functional unit is isolated from each other to prevent the expansion of faults. When the drawer is pulled out of the cabinet, the live parts inside the cabinet are not exposed, ensuring safety and reliability.
3. The drawer guide rail adopts a new type of three section guide rail, which has strong bearing capacity. After the drawer is pulled out, it can be inspected without removing it. The matching accuracy is high, which can ensure accurate positioning of the primary and secondary contacts; There are three obvious positions for connecting, testing, and separating functional units during insertion and extraction, and they have good interchangeability.
