SINTEF Energy is working with:
Study of power line components exposed to mechanical, chemical and electrical stresses, which can affect the lifetime of the overhead transmission line. Current power line components are:
- Dead end clamps
- Suspension systems
- Cross arms (aluminium, wood, steel, composite)
- Towers (wood, steel, composite)
- Foundation and anchoring
- Testing of the mechanical strength of new and old power cord components. Can be combined with power load.
- Improvement of the mechanical and electrical ability to maintain contact the power, through improved design and correct torque.
- The implementation of the type of tests, including dead end joints, suspension clamps, conductors and insulators.
- Condition and lifetime analysis.
- Surveys of the aging processes such as wear, fatigue and corrosion rate.
- Testing of the dynamic response of suspension systems in order to avoid wear and fatigue
- Investigation the mechanical-and electrical strength of insulators.
- Failure analysis.
- Mapping of atmospheric corrosion environment and its salt deposit density.
- Development and evaluation of inspection methods.
SINTEF Energy has following relevant laboratories and equipment
- Universal mechanical test equipment (200kN).
- Salt mist chamber.
- Jig for bending tests of about 20m long poles.
- Jig for bending tests of cross arms.
- Jig for testing the dynamic response in suspension systems due to vibration and wind.
- Jig for stress strain testing of clamps. Measurement of "spring constant" improving the creep properties.
