Advantages of LV Switchgear

Safety

LV switchgear incorporates various protective mechanisms to ensure the safety of personnel and equipment. It isolates faulty circuits, prevents electrical hazards, and minimizes the risk of electrical fires or accidents.

Reliability

By offering control, protection, and isolation capabilities, LV switchgear enhances the reliability and availability of electrical power. It helps prevent downtime and ensures uninterrupted power supply to critical loads.

Flexibility

LV switchgear provides flexibility in managing power distribution. It allows for easy reconfiguration and expansion of electrical systems, facilitating changes in operational requirements and adapting to evolving needs.

Maintenance

Switchgear enables efficient maintenance of electrical equipment. By isolating faulty components, it simplifies troubleshooting and repairs, minimizing downtime and improving overall system maintenance.

Application of LV Switchgear

Commercial buildings

Offices, shopping centers, and healthcare facilities for reliable power distribution.

Industrial facilities

Manufacturing plants, refineries, and production facilities to ensure uninterrupted operation.

Infrastructure

Airports, railways, and utility substations for essential power distribution and control.

The Main Parts of LV Switchgear

Breaker compartment
Each breaker compartment can normally hold up to four power circuit breakers arranged in a vertical fashion. Each power circuit breaker is individually compartmentalized from other breakers.

Bus compartment
Behind the circuit breaker compartment is the bus compartment which is also compartmentalized by solid barriers from the breaker compartment. Adjacent bus compartments are segregated from each other by an insulated barrier between compartments.

Cable compartment
The cable compartment is at the rear of the switchgear section and it is optionally compartmentalized with vented or unvented barriers from the bus compartment. The cable compartment has hinged doors or removable covers that enable access to landing lugs for terminating line and load cables. This compartment arrangement is the most typical and may be called rear-accessible switchgear since access to the back of the switchgear enclosure is required.

How to Maintain LV Switchgear

Preventative maintenance

Preventative maintenance plays a crucial role in ensuring the reliable and efficient operation of your LV switchgear. Our skilled technicians will conduct thorough inspections of your switchgear components, identifying any signs of wear, corrosion or loose connections. Through regular preventative maintenance, we can help you mitigate potential risks and extend the lifespan of your LV switchgear.

Periodic maintenance

Periodic maintenance of LV switchgear involves a systematic process to ensure optimal performance and reliability, including visual inspections, cleaning, tightening connections, verifying insulation levels, and testing protective devices. Regular checks of circuit breakers, relays, contacts & busbars help identify and address potential issues. This approach reduces the risk of failures, ensuring uninterrupted power supply.

Conditional maintenance

We also provide conditional maintenance services for your LV switchgear, monitoring critical parameters or indicators to identify signs of potential failure or performance decreases. Using advanced diagnostic tools like thermal imaging and electrical testing, we can detect and resolve potential issues like overheating and insulation degradation & abnormal electrical behaviour.
