LineROVer – A compact robot for inspecting overhead lines

The lightweight and compact LineROVer was originally developed for deicing overhead ground wires and conductors. Over time, many additional overhead transmission line inspection and maintenance applications have been found for this remotely-operated robot that can operate even on energized lines.

LineROVer is simple to use and install and is the ideal tool for a wide range of work in hard-to-reach locations.

LineROVer benefits

Continuity of service: Works on energized lines without interrupting service
Lightweight: 23-kg vehicle that can be used on small-gauge cables
Portability: Compact for easy transportation and deployment
Simplicity: Easy to operate
Flexibility: Able to negotiate splice sleeves
Versatility: Compatible with most conductor types
Ruggedness: Reliable mechanical and electronics systems
Very high traction

LineROVer applications

Visual inspection
Verification of splice condition (by measuring resistance)
Infrared imaging
Corrosion detection (using the LineCore sensor)
Overhead ground wire and conductor de-icing
Replacement of conductors, overhead ground wires and optical ground wires (OPGW) using the cradle block method
Conductor repair

Typical LineROVer use cases

Hard-to-reach segments, such as spans in mountainous or agricultural regions and water, distribution line, highway and railway crossings
Lines exposed to conditions likely to reduce equipment service life:
- Marine climate, atmospheric pollution
- Areas subject to adverse weather conditions (wind, lightning, ice, etc.)
Strategic segments where continuity of service is essential (interconnection with neighboring systems, supplies to industrial or densely populated areas)

Value creation

Increased productivity compared to other inspection and repair methods
Reduced asset downtime
Non-destructive in situ evaluations
Precise and detailed data to support maintenance decisions
Reduced costs through deferred capital spending
Prioritization of asset maintenance projects
Extended equipment service life
Reduced risk and increased asset stability and reliability
Enhanced worker health and safety
