FAQ
- What is Withdrawable Low Voltage Switchgear?
- A withdrawable switchgear that includes protective and control devices, allowing maintenance and replacement of internal components without shutting down the entire power supply. It provides multiple output feeders according to the user’s distribution system requirements, and includes overcurrent, short-circuit, and other protective functions.
- Where are these switchgears used?
- In power plants, large factories, data centers, and projects that require high reliability and fast access.
- What is the advantage of a withdrawable design compared to fixed design?
- Due to the Metal Clad structure, the cable entry, main switch, busbar, and drawers are separated from each other. This allows quick replacement of drawers and main switches, reduced maintenance time, and increased operator safety.
- Are these switchgears customizable?
- Yes, they can be designed and configured according to project requirements for voltage, current, and protective devices.
