Transmission Line Assessment

Comprehensive, practical services for all aspects of transmission line assessment, including detailed field inspections of line components.

Kinectrics has established an outstanding record in supporting the reliability and safety of numerous key transmission facilities in North America for several decades. Our transmission line assessment services include:

Conductors, Skywires, Line Hardware and Insulators

  • Aging and remaining life assessment for transmission lines

Corrosion Prevention and Control

  • In situ field inspections of line components and tests to determine the need for maintenance and refurbishment
  • Recommendations of practical solutions
  • Identification of key environmental parameters in the corrosion process, and monitoring of the severity and frequency of their occurrence over an area of interest

Tower Tests

  • Full scale, in situ tests using remote loading and instrument recording equipment

Foundation Assessment

  • Inspection, uplift, compression and lateral load tests on various types of foundations, including concrete footings, steel grillages, rock and soil anchors and piles
