GCS withdrawable low-voltage switchgear
The GCS type withdrawable low-voltage switchgear (hereinafter referred to as the device) is a low-voltage withdrawable switchgear designed and developed by two joint design teams based on the requirements of industry regulatory authorities, power users, and design units. It meets the national conditions, has high technical performance indicators, can adapt to the development needs of the power market, and can compete with existing imported products. The device has been widely used by power users.
GCS is applicable to power distribution systems in industries such as power plants, petroleum, chemical, metallurgical, textile, and high-rise buildings. In large cold power plants, petrochemical systems, and other places with high automation and computer interface requirements, it is a low-voltage complete distribution device used for power distribution, motor centralized control, and reactive power compensation in power generation and supply systems with three-phase AC frequency of 50HZ, 60HZ, rated working voltage of 380V, (400V, 660V), and rated current of 4000A or below.
Product features
- GCS frame is adopted with the double folding technology of aluminum zinc steel plate, and modular holes are arranged at intervals of 25mm (K-shaped profiles) on the frame. The frame assembly is convenient and sturdy.
- The entire frame is precisely connected by horizontal and vertical bolts, and the frame structure is maintenance free. The shell is covered with electroplating and powder coating to ensure the highest durability. The top cover of the horizontal busbar area can be disassembled for easy on-site busbar installation.
- The main busbar system installed on the top of the switchgear is completely isolated from the functional units, cable area, and secondary line horizontal wiring area, ensuring sufficient safety distance between the busbar and operation and maintenance personnel
- The drawer style structure canaccommodate up to 36 circuits, which is economical, reliable, and saves on-site space. Three position conversion of drawer circuit can be achieved without reducing the protection level.
- The drawer style structure can accommodate up to 36 circuits, which is economical, reliable, and saves on-site space. Three position conversion of drawer circuit can be achieved without reducing the protection level.
- When the switch is in the closed position, the drawer component door cannot be opened.GCS can be optional front door of fully transparent explosion-proof glass. Easy observation and beautiful appearance.

How long does it take to full charge an EV?
This depends on the EV battery size, remaining battery capacity, and the type of EV charger used as well as environmental conditions such as temperature.Typically, an AC charger with an output power of 7–22 kW can fully charge an EV in between 3 and 6 hours.With a 50–200-kW DC fast charger, the charge time can be reduced to 10–60 minutes.
What’s the difference between AC and DC charging?
An AC charger provides AC power, which is then converted to DC power by an onboard charger inside the EV (before it reaches the battery). AC chargers are normally used in slow-charging applications such as home charging. A DC charger converts AC power from the grid into DC power, which is more efficient and supplies the batteries directly. Thus, the charging time is markedly shorter. DC chargers have higher power requirements and therefore a higher installation complexity. As such, the installation cost can be higher than that for an AC charger. DC systems are generally used in commercial/public charging applications where shorter dwell tines are needed
Which EV charger should I choose?
This depends on your situation. Fast DC chargers are ideal for cases where you need to recharge your EV quickly, such as at an intercity highway charging station or rest stop. An AC charger is suitable for places where you stay longer, such as workplace, shopping malls, cinema and at home.
