Tender for Fault Detection & Rectification of HT Underground Cable at Khambhalia Division

The scope of work includes:

• Fault detection and diagnosis of underground HT cables using advanced testing methods.
• Rectification of identified faults to restore optimal cable performance.
• Testing and commissioning of repaired cables to ensure compliance with standards.
• Documentation and reporting of all activities performed.

The process involves:

1. Initial site assessment and fault location.
2. Preparation of necessary tools and equipment.
3. Execution of fault detection procedures as per technical guidelines.
4. Fault rectification including cable splicing, jointing, or replacement.
5. Final testing to verify cable integrity.
6. Handover of the completed work with detailed reports.

Bidder must ensure compliance with all safety and technical standards throughout the project.

The technical specifications require bidders to use testing equipment capable of detecting faults in underground HT cables at voltage levels up to 33kV. The detection methods should include Time Domain Reflectometry (TDR) and insulation resistance testing, with the following parameters:

plaintext

• Cable Length: Up to 1000 meters
• Voltage: 11kV / 33kV
• Fault Location Accuracy: ±1 meter
• Equipment Certification: ISI or equivalent

Sequential process for technical execution:

1. Conduct initial site survey.
2. Use certified testing equipment to locate faults.
3. Perform necessary repairs following safety standards.
4. Verify repairs through final testing.
5. Document all technical activities for approval.

The total estimated budget for this project is ₹4,90,000. The cost breakdown includes:

Payment terms:

• 30% advance upon contract signing.
• 40% after completion of fault detection and rectification.
• 30% post final testing and approval.

Bidders must submit a detailed financial proposal aligned with these guidelines, ensuring transparency and compliance with government procurement norms.
