GCS Low Voltage Withdrawable Switchgear

Comewill high qaulity GCS low voltage withdrawable switchgear has high making and breaking capabilities, good dynamic and thermal stability, an advanced and reasonable structure, a flexible electrical scheme, a high protection level, safety and reliability, ease of maintenance, and excellent technical performance indicators.

Feature

1.The cabinet frame of GCS low voltage withdrawable switchgear adopts double-folding technology and is fabricated from aluminum-zinc-coated steel plates. Designed with modular 25mm-pitch holes (K-profile), the frame boasts a straightforward structure and exceptional durability. Assembled with precise transverse and longitudinal bolt connections, the entire frame requires no maintenance throughout its service life.
2.The cabinet shell undergoes electroplating and powder coating for enhanced protection. The top cover of the horizontal busbar compartment is detachable, facilitating on-site busbar installation and reducing operational complexity.
3.Functional zones within the cabinet are clearly partitioned, mainly comprising functional unit compartments and cable compartments. Each unit operates independently with isolated functions, ensuring no mutual interference between different components.
4.The horizontal busbar is mounted horizontally at the bottom of the cabinet, significantly improving its ability to withstand the electrical stress induced by short-circuit currents.
5.Featuring a drawer-type structure, the cabinet can accommodate up to 36 circuits, each with a rated current of 400A or lower. The drawer circuits support three-position conversion without compromising the cabinet’s protection rating.
6.Each functional unit can house a maximum of 11 full-size drawers or 22 half-size (1/2) drawers, offering flexible configuration options.
7.Drawers are equipped with five operational positions: Open, Closed, Test, Extracted, and Isolated. Corresponding audio, visual, and textual indicators provide clear status signals for intuitive operation.

Product Overview

The GCS Low Voltage Withdrawable Switchgear, independently developed and supplied by Welcome (Wenzhou) Electric Co., Ltd., is a premium-performance complete set of equipment tailored for low-voltage power distribution systems—an ideal choice for engineering procurement, project matching, and bulk equipment procurement. Integrating a scientific modular structure with reliable electrical performance, this switchgear is widely procured and applied in key scenarios such as power plants, industrial workshops, high-rise buildings, and large-scale commercial complexes, serving as a core device for power distribution control and precise energy allocation.
Its core procurement advantage lies in the advanced "withdrawable" design: each functional unit (including circuit breakers, contactors, etc.) can be easily withdrawn or inserted without disrupting the overall system operation. This significantly simplifies post-procurement maintenance and repair processes, minimizes equipment downtime, and effectively reduces the overall operation and maintenance costs for procurement parties.
During production, Welcome (Wenzhou) Electric Co., Ltd. adheres to strict quality control standards, adopting high-grade insulating materials and precision manufacturing techniques. The switchgear is equipped with multiple comprehensive safety protection mechanisms (short-circuit protection, overload protection, etc.), enabling it to stably adapt to complex power grid environments and ensure the safe and continuous operation of the distribution system—fully meeting the high-reliability requirements of procurement projects. Additionally, its flexible modular design supports on-demand expansion, which can accurately match the customized procurement needs of different projects for varying capacities and control modes, enhancing the adaptability and cost-effectiveness of procurement. As a cost-effective, efficient, and safe low-voltage power distribution equipment, it has become a trusted procurement option in the modern low-voltage power distribution field.
This GCS low voltage withdrawable switchgear fully complies with international and national relevant standards such as IEC60439-1, GB7251.1 "Low-voltage complete switchgear and control equipment" and GB/T 24274 "Low-voltage withdrawable complete switchgear and control equipment", ensuring that procurement projects meet standardization and compliance requirements, and providing solid quality assurance for procurement decisions.

Normal Use Environment Conditions

Ambient Temperature: The ambient air temperature shall not exceed +40℃ or be lower than -5℃, and the 24-hour average temperature shall not exceed +35℃. For procurement projects involving usage beyond the above temperature range, the GCS low voltage withdrawable switchgear must be operated at reduced capacity to ensure operational safety and performance stability.
Relative Humidity: When the maximum ambient temperature reaches +40℃, the relative humidity shall not exceed 50%. Higher humidity is permissible at lower temperatures (e.g., 90% relative humidity at +20℃). During procurement and subsequent installation, sufficient consideration shall be given to the potential condensation risks caused by sudden temperature changes to avoid equipment failure.
Altitude: The standard installation site altitude shall not exceed 2000m above sea level. For procurement projects in areas above 2000m, the equipment must be correspondingly derated for use, and relevant requirements shall be clearly specified in the procurement contract.
Installation Site Conditions: The switchgear shall be installed in locations free from fire hazards, explosion risks, heavy dust, chemical corrosion, and severe vibration or impact. Procurement parties shall confirm that the on-site environment meets the above requirements before delivery to ensure the equipment's service life and reliability.
Special Environment Negotiation: If the actual use environment of the procurement project fails to meet the aforementioned requirements, the purchasing party shall promptly communicate and negotiate with Welcome (Wenzhou) Electric Co., Ltd. to formulate customized solutions (such as special material upgrades or structural improvements) to ensure compliance with project operation needs.

Main Technical Parameters

Note: For the rear wiring solution, a cabinet depth of 1000mm is recommended.
