Cable joint failure modes, contributing factors and solutions outline.
|Application of mechanical forces
|Contraction and expansion of metallic materials
|Trifurcation of cable
|Excess cable for conductor expansion and contraction
|Installation of steel frames for mechanical strength
|Insufficient thermal dissipation
|Incorrect thermal resistivity of materials
|Utilisation of location based thermal resistivity data
|Circuits operating close to or over the design ratings
|Understanding of wind farm design principles
|Correct application of cable optimisation techniques
|Installation and workmanship quality
|Poor workmanship due to inadequate training and workplace skills
|Adequate and tailored training and education pathways for wind farm cable jointers
|Incorrect technology application
|Incorrect application of componentry and technology
|Ensure technology and componentry has been designed, tested and manufactured specifically for wind farm applications
