Compression deadends are designed to securely anchor and support powerlines, preventing them from sagging or coming loose under various environmental conditions, such as strong winds, ice, or heavy loads. They are typically installed at the endpoints of powerline spans or where changes in direction occur.
Features:
▶ Securely anchors and supports powerlines
▶ Minimises sagging and prevents line loosening
▶ Distributes tension evenly along the powerline
▶ Withstands high mechanical loads and reduces stress concentrations
OH&S Considerations:
Electrical Safety: Powerlines carry high voltages, making electrical safety a critical concern. Workers must follow proper lockout/tagout procedures, de-energise the powerline before working on the dead end, and use insulated tools and equipment to minimise the risk of electric shock.
Fall Protection: When working at heights during the installation or maintenance of compression dead ends, workers should utilize fall protection measures such as harnesses, lanyards, and anchor points to prevent falls.
