Low voltage switchgear and control equipment are commonly known as low voltage switchgear, also known as low-voltage distribution cabinet, which refers to a complete set of electrical equipment with AC and DC voltage below 1000V.

The lv switchgear is designed for AC 50Hz, 380V distribution systems used for power conversion and control of power, lighting, and distribution. This product features strong breaking capacity, excellent dynamic thermal stability, flexible electrical solutions, easy assembly, a wide range of systems, strong practicality, and a novel structure.

Our company’s low voltage switchgear types include MNS Withdrawable Switchgear, GGD Fixed Type Switchgear, XL-21 Power Distribution Panel, GCS Series LV Switchgear, GCK Series LV Switchgear, GGJ Reactive Power Compensation Cabinet and etc.Here is our lv switchgear product catalog.

The Role of Low Voltage Switchgear

Power Distribution

LV switchgear is the core part of the distribution system. It distributes electricity from the transformer or the medium voltage switchgear to various load points, such as distribution boards, lighting systems, and industrial equipment.

Control & Management

Provides centralized control of circuits, enabling smooth switching operations and start/stop control of equipment. This ensures greater flexibility and reliability in power systems.

Electrical Protection

Equipped with circuit breakers, contactors, and fuses, the lv switchgear can quickly cut off power in the event of short circuits, overloads, or leakage faults, protecting both people and equipment.

Safety Isolation

During equipment inspection or maintenance, the switchgear offers reliable isolation to ensure a safe working environment without electrical hazards.

Power Quality Improvement

Some lv switchgear comes with reactive power compensation devices, which help improve power factor, reduce losses, and increase energy efficiency.

Common structural types of low voltage switchgear

According to the structure

• Fixed switchgear: Once installed, the equipment is essentially immovable, offering lower costs but inconvenient maintenance.
• Withdrawabled switchgear: Functional units (drawers) are freely pluggable, facilitating maintenance and expansion. It is commonly used in factories and large buildings.

Switchgear Structural Connection Types

• Welded Structure: The steel plates or steel sections of the cabinet are fixed into a whole by welding.
• Fastener (Bolted) Structure: The cabinet is assembled using screws, bolts, and other fasteners.

Low voltage switchgear is the component of the power system closest to users and is widely used in factories, buildings, municipal projects, and new energy projects. It not only ensures the safe distribution of electricity but also provides strong support for energy conservation and efficient management through intelligent functions.
