Low Voltage Switchgear Withdrawable Switchgear

Overview 

The Low voltage switchgear provides a highly versatile solution for modern industrial power systems. This modular LV switchgear employs advanced manufacturing processes and high-quality electrical components, offering high flexibility and scalability to meet diverse user needs. The withdrawable switchgear design ensures that you can replace functional units quickly without shutting down the entire plant. It follows international standards so your power system remains stable and efficient.

Operating Conditions

• Ambient air temperature: -5°C to +40°C; 24h average ≤ +35°C.

• Atmosphere: Clean air; ≤50% RH at +40°C, ≤90% RH at +20°C; occasional condensation allowed.

• Altitude: ≤2000m.Transport/storage temperature: -25°C to +55°C; short-term up to +70°C (≤24h) with no permanent damage.Unmet conditions require user-manufacturer negotiation.

• When the device is used on offshore oil drilling platforms and nuclear power plants, a separate technical agreement shall be signed

Product Features

• Modular Frame：This distribution cabinet uses standardized components and so you can modify the layout for specific project needs.

• High Current Reliability：The electrical distribution board handles up to 6300A safely because we use premium copper for all busbars.

• Superior Operator Safety：This low voltage switchboard features full internal separation but maintains easy access for routine maintenance and monitoring.

• Compact Structural Design：Each electrical switchgear box maximizes internal space so you can install more units in a smaller area.

• Smart Power Management：This power distribution equipment provides precise control of electrical loads and so it reduces overall energy waste.

• Logical Circuit Layout：The electrical distribution panel organizes all circuits clearly because fast troubleshooting is essential for industrial productivity.

• Durable External Protection：Our switch cabinet protects the sensitive electrical switchgear inside from dust and environmental hazards effectively.

The IP54 protects against dust and splashes in any direction.

(IP54 protection should be ordered in consultation with the manufacturer)

Cabinet structure

The basic structure of the switchgear cabinet is composed of C profile assembly. Section C is made of steel plate with E=25mm module mounting hole. All cabinets and inner partitions are galvanized and purified.

Around the door panels, the side panels are made of high voltage electrostatic

Switch cabinet type

Power distribution center cabinet (PC): Emax, MT, 3WN, AH, ME series circuit breakers can be used.

Motor control center cabinet (MCC): assembled by large and small drawers, the main switch of each circuit adopts high break plastic-case circuit breaker or rotary load switch with fuse.

Automatic power factor compensation cabinet (with manual, automatic and remote power factor compensation devices)
