When a line design calls for a bare overhead conductor, the choice between ACSR and AAAC comes down to a trade-off between mechanical strength, conductivity, weight and corrosion behaviour. Here is how procurement and line-design teams usually decide. ACSR — strength for long spans Aluminium Conductor Steel Reinforced uses a galvanised or aluminium-clad steel core […]
AS/NZS 3607 tabulates the stranding, dimensions and mechanical and electrical properties of aluminium and ACSR conductors. Knowing which columns matter makes it quick to confirm that what arrives on the drum matches what was specified. Stranding and construction The construction column gives the number and diameter of aluminium and steel wires — for example 54/7 […]
When a utility wants fibre along its transmission route, the choice is usually between OPGW and ADSS. The decision turns on whether the line is new or existing, and whether it can be de-energised. OPGW — fibre in the earth wire Optical Ground Wire replaces the conventional earth wire with a cable that combines the […]
