GCS Low Voltage Switchgear

HAGOE GCS Low Voltage Switchgear is designed for power distribution systems in power plants, petrochemical facilities, metallurgy, textile plants, high-rise buildings and other large-scale industrial applications. It is suitable for 50/60Hz three-phase AC systems with rated working voltages of 380V/400V and 660V, and rated current up to 4000A. The withdrawable architecture supports low-voltage power distribution, centralized motor control and reactive power compensation, making GCS suitable for highly automated facilities requiring integration with computer-based control systems.

GCS Low Voltage Switchgear is more than a conventional low-voltage distribution cabinet. It is a complete switchgear system developed for high-capacity, multi-circuit and highly automated distribution applications.

In large power plants, petrochemical facilities, metallurgical production lines and high-rise buildings, the low-voltage system may be required to handle incoming power distribution, outgoing feeders, centralized motor control and reactive power compensation within the same electrical infrastructure.

GCS uses withdrawable functional units to organize different electrical functions within a structured cabinet arrangement, allowing circuits to be configured according to actual load requirements.

With rated current up to 4000A, GCS is particularly suitable for large low-voltage distribution systems rather than conventional end-user distribution alone.

Model Definition

GCS Low Voltage Switchgear

Three Core Electrical Functions in One System

GCS can be configured around three major electrical functions:

Low-Voltage Power Distribution
Used for incoming power, busbar distribution and multiple outgoing feeder circuits.

Centralized Motor Control
Designed for centralized control of production machinery, pumps, fans, compressors and other industrial motor loads.

Reactive Power Compensation
Reactive compensation functions can be incorporated according to the system design to support power-factor management and more efficient utilization of electrical power.

For highly automated industrial facilities, GCS can also be configured for interface integration with supervisory computers, PLCs and other control systems, allowing the switchgear to work as part of a broader industrial automation architecture.

Withdrawable Architecture for High-Circuit-Density Systems

GCS uses a withdrawable low-voltage architecture, allowing functional units to be arranged according to the distribution scheme.

Large industrial projects may require multiple circuits with different ratings and functions within the same switchgear lineup. With a completely fixed configuration, circuit maintenance, system modification and equipment servicing can become more restrictive.

GCS organizes circuits through withdrawable functional units, creating a more structured arrangement for distribution, control and protection functions.

This architecture is particularly suitable for:

Multi-feeder distribution systems

Centralized MCC applications

Large industrial automation projects

Production systems requiring efficient equipment maintenance

Designed for Automated Industrial Power Systems

GCS is particularly suitable for distribution systems requiring computer interfaces and higher levels of automation.

Modern industrial power systems need more than basic power distribution. Operators may also need access to operating status, circuit parameters and control information. Low-voltage switchgear therefore needs to interface effectively with the broader industrial control architecture.

Depending on project requirements, GCS can incorporate appropriate measurement, protection and control components and interface with PLCs, supervisory systems or industrial computers.

This combination of power distribution and control makes GCS suitable for continuous-production industries such as petrochemicals, metallurgy, power generation and textile manufacturing.

GCS Low Voltage Switchgear

GCS Low Voltage Switchgear vs. GCK

Both GCS and GCK use withdrawable architectures, but their typical engineering applications are different.

GCK is commonly used for industrial low-voltage distribution and motor control, with emphasis on PC and MCC applications.

GCS is more oriented toward high-capacity, high-density and highly automated low-voltage distribution systems. With rated current up to 4000A, it is designed for integrated applications involving large-scale distribution, centralized motor control and reactive power compensation.

Product selection should therefore consider:

System Capacity → Number of Incoming/Outgoing Circuits → Motor Loads → Automation Requirements → Reactive Compensation → Installation Space → Maintenance Requirements

Applicable Industries

Power Plants

GCS can be used in low-voltage auxiliary power systems in power plants, providing centralized distribution and control for auxiliary equipment, motor loads and other low-voltage loads.

Petrochemical Facilities

Petrochemical facilities typically involve continuous operation and high levels of automation. GCS can be applied to power distribution and centralized motor control within these environments.

Metallurgy and Heavy Industry

For large production lines and high-power motor loads, GCS provides a structured solution for multi-circuit low-voltage distribution and centralized control.

High-Rise Buildings

GCS can be integrated into low-voltage distribution systems in large buildings for centralized distribution of power, lighting and other low-voltage loads.

Design Standards and Compliance

The GCS system is designed in accordance with applicable standards for low-voltage switchgear and controlgear, including:

  • IEC 439-1 — Low-Voltage Switchgear and Controlgear
