Operational Current Cabinet (OCC)

An Operational Current Cabinet (OCC) cabinet is an essential part of electrical power systems, providing efficient distribution and control of operating power. It also ensures a stable output voltage regardless of fluctuations or power outages in the main supply network.

OCC cabinets play a vital role in the safe and reliable operation of electrical equipment, while enabling continuous monitoring of system parameters such as voltage, current, and battery charge level. They are widely used in relay protection, automation, communication systems, and other auxiliary electrical equipment.

Benefits of Using OCC Cabinets

The use of an Operational Current Cabinet (OCC) provides the following advantages:

• Ensures uninterrupted operation of electrical equipment.
• Automatically maintains batteries in a charged state, providing backup power during supply outages.
• Optimizes energy consumption and helps reduce electricity costs.
• Improves the overall efficiency of the power supply system.
• Reduces downtime and maintenance time.
• Provides maximum protection against fault conditions and equipment damage.
• Offers easy access to wiring and switching devices for maintenance.
• Suitable for a wide range of industrial applications and facilities with different power supply requirements.

The OCC cabinet features a robust, high-strength enclosure that ensures long service life and reliable operation in demanding environments. It is equipped with an automatic protection system that disconnects the circuit in the event of voltage fluctuations or short circuits, safeguarding electrical equipment and helping prevent fire hazards.

Structural Composition

An Operational Current Cabinet (OCC) consists of the following main components:

1. Enclosure – made of steel or high-strength plastic.
2. Doors – available in single-, double-, or triple-door configurations depending on the cabinet size and layout.
3. Distribution equipment – including distribution boards, circuit breakers, fuses, and related components.
4. Wiring and interconnection components – cables, conductors, and connection terminals for linking equipment to the power supply and auxiliary devices.
5. Rectifier units – convert AC mains power into DC power required by connected loads.
6. Battery chargers – maintain and recharge the backup battery system.
7. Battery banks – provide emergency DC power during mains power failures.
8. Microprocessor controller – manages and monitors the operation of the entire system.
9. Ventilation system – ventilation openings and cooling fans ensure proper airflow and temperature control inside the cabinet.
10. Security mechanisms – including locks, keypad access, or other protection systems for safe operation.

 

The OCC cabinet has an average service life of 25 years and is available with IP20, IP31, or IP54 protection ratings.
