Electrical discharges can significantly damage the bimetal on the front part of the arm, making its replacement necessary.
Brar performs bimetal replacement following a structured process:
- Removal of the old bimetal
- Welding of new pre-fabricated plates
- Mechanical processing of the front part
- Testing and final inspection
One of the most common issues during operation is the formation of electrical discharges on the front part of the arm.
This phenomenon is often caused by imperfect contact between the copper plate and the arm itself, resulting from the progressive loosening of the clamping bolts.
When the plate does not adhere properly, the bimetal experiences significant wear, necessitating its replacement to restore operational efficiency.
Replacing the bimetal is a precise procedure that must be carried out carefully, following a series of well-defined steps:
1. Removal of Damaged Bimetal
The compromised front section of the bimetal is removed to prepare the surface for the application of new plates.
2. Welding of Pre-Fabricated Bimetal Plates
Pre-fabricated bimetal plates are welded in place, ensuring perfect adhesion and optimal electrical conductivity.
3. Mechanical Processing of the Arm's Front Section
The arm’s surface is meticulously processed to ensure seamless integration of the new bimetal, enhancing the system's reliability and durability.
4. Testing and Final Inspection
The system undergoes rigorous testing and inspection to verify proper functioning, ensuring no electrical discharges occur and that the bimetal has been correctly installed.
This process ensures that the system returns to operating at maximum efficiency, preventing further damage and ensuring optimal performance over time.
Every maintenance and repair intervention is tailored to meet the specific needs of our clients.
Brar ensures reliability and efficiency at every stage of the process, maintaining high-quality standards in all types of interventions.
