Conductor Clashing on Overhead Lines: Why Wind Trips Feeders and What Covered Conductor Changes
Conductor clashing trips overhead feeders in wind and leaves no trace. This post sets out why bare phases clash, what the usual remedies cost, and what a covered…
Congested Corridors and Crossings: Where Covered Conductor Beats Bare Wire and Underground Cable
Rivers, rail crossings, forest edges and narrow urban rights of way push bare overhead lines and underground cables to their limits. This post sets out where medium voltage…
Heat and Vibration in Engine-Bay Wiring: Why Harnesses Fail and How to Specify Against It
Most engine-bay wiring faults trace back to heat ageing, chafing and vibration fatigue at terminations. How each failure starts, and what a harness specification should demand to prevent…
Tree Contact on 11 kV and 33 kV Feeders: Why Covered Conductor Is the Practical Fix
Branches, creepers, birds and clashing phases cause most trips on forest and tree-lined feeders. How covered conductor removes those faults, where ABC and underground cable fit, and what…
Sheath Bonding for Single-Core Cables: Why Circulating Currents Waste Capacity
Earthing the sheath of a single-core cable at both ends creates a circulating current that heats the cable and takes away rating. Solid, single-point and cross bonding compared,…
Why the Longest Cable Run Should Decide the Conductor Size
A cable can pass every current-carrying check on paper and still starve the equipment at the far end. On long runs, voltage drop, not ampacity, decides the conductor…
