Electrical Utility
Design, Engineering, Supply, Erection, Liaisoning & Commissioning work of Electrical Utility Shifting for 33 KV,11 KV, LT Lines.
Electrical Utility Shifting for 33 KV, 11 KV, LT Lines, and Transformers involves relocating existing electrical infrastructure to facilitate construction, development, or infrastructure projects. This process requires meticulous planning, engineering, and execution to ensure minimal disruption to services and compliance with safety regulations.
Applications
- 1 Urban development projects, such as road widening or metro construction.
- 2 Industrial and residential area expansions.
- 3 Projects requiring clearance of right-of-way (ROW) for new infrastructure.
Challenges and Mitigation
- Coordination with stakeholders:
Engaging utility providers, contractors, and local authorities to minimize delays. - Live line handling:
Using trained personnel and modern equipment to work on energized systems when necessary. - Minimal downtime:
Employing advanced planning to ensure continuous power supply during shifting.
Research
Relocating electrical utilities, including 33 kV, 11 kV, and low-tension (LT) lines, as well as transformers, is a critical aspect of infrastructure development projects. This process ensures that existing electrical infrastructure does not impede new construction or expansion activities.
Scope of Work
Conducting a detailed survey of the existing electrical network to identify the components requiring relocation.
Assessing the feasibility of the new alignment for the 33 KV, 11 KV, and LT lines, as well as transformer locations.
Preparing detailed engineering designs and drawings for the proposed shifting.
Ensuring compliance with applicable electrical standards and codes (e.g., IS standards or local regulations).
Arranging the required materials, including poles, conductors, insulators, and transformers.
Using galvanized steel, aluminum, or other suitable materials to ensure durability.
33 KV and 11 KV Lines
- 1 Erection of new poles or towers.
- 2 Stringing of conductors and installation of necessary hardware, including isolators and circuit breakers.
LT Lines
- 1 Shifting and reinstallation of low-tension lines with proper insulation and connections.
Transformers
- 1 ERelocating existing transformers or installing new ones, including associated civil works for transformer pads or enclosures.
Conducting pre-commissioning tests to ensure the integrity and safety of the shifted utilities.
Energizing the lines and transformers with load testing to verify performance.
Safely dismantling old infrastructure.
Proper disposal of dismantled components as per environmental regulations.
Ensuring worker and public safety by adhering to best practices, such as proper grounding and insulation.
