The Railway division is presently handling a diverse order book with a portfolio of projects across various functional segments. The Order book pie comprises Civil Infra (80%), Electrification (11%) and Signalling & Telecom(9%) projects. The client base covers many of the Zonal railways and other Railway organizations under Indian Railways. The division is further leveraging its global presence in the Power transmission sector, and eyeing to target Railway turnkey projects around the globe, particularly in Africa , Middle East, South East Asia & South Asia.

KEC had been one of the earliest players in Railway Electrification in India - having completed a total of 5000 Track km of Electrification on Indian Railways, with 1700 Tkm (Track km) of overhead electrification work (25 kV AC) coming in the last 7 years. Over the years, the company has transformed into a complete turnkey solution provider of Railway construction in EPC space, capable of executing projects in all terrains and geographies.

 

Cables

The Cables Division is equipped to provide Total Cable Solutions in the field of Power Evacuation to our customers. This is achieved through constant INNOVATION and significant differentiation by:

Providing solutions for evacuation of Power through Cable selection and cabling system Low Cost and High Quality Products & Services through our partnerships with renowned vendors. Timely Installation, Erection and Commissioning.

The Scope

Engineering

• Designing of HT & EHV Cabling System which includes designing of cable layout/route, cable, bonding systems along with route survey drawing.

PROCUREMENT

• Cables
• Joints & Termination Cable Bonding Accessories

CONSTRUCTION

• Cable Laying
• Jointing & Termination
• Installation & Commissioning

PRELIMINARIES

• Statutory Approvals
• Route Survey Drawings/Route Finalization
• Erection Program Finalization
• Tools and Tackles

The Laying Methods

• Laying in Ground
• Drawing in Ducts
• Erection Program Finalization
• Laying on racks in air
• Laying one racks inside tunnel
• Laying along Building/Structure

The Economics

• Route Selection
• Least obstacles route identification
• Fewer road crossing
• Fever transportation issues
• Easy movement of cable drums
• Proper location for joints & end termination
• Permissible Bending radii
• Permissible vertical height
• Max. Permissible tensile strength for cable
• Availability of Cable – Proper size & qty

The Technology

• Clearance: HV Cables should be at a safe distance from Control/Instrumentation Circuits.
• Trenching: It should be of minimum width and depth. It should be provided with sand bedding.
• Protection: Covers, Clamps, Normal Backfills and Warning Tapes must be used.
• Final : Route markers must be installed followed by final backfilling consolidation

Finally, Testing & Commissioning ensures alignment of cables, proper joints and terminations. Tests like Insulation Resistance and Sheath Integrity needs to be conducted and recorded. Pre-Commissioning test at 38 kV AC at no load for 24 hours after due approvals is done and then the system can be charged.

Power evacuation through total cabling solutions is both an art and a skill which is best left to the experts in the business.
