Installation of Electrical Conduits in Melbourne

February 28, 2018

Melbourne natives are used fuss-free landscapes. After that boast, we can't just allow electrical cables to run along a surface any old way. That's why a cable installer strives to make a cable run look its best. Better yet, those wires should be heavily protected. The answer is to use electrical conduits. Rigid, running as straight as an arrow, these armoured cabling channels assure a tightly imposed aesthetic.

Installing Above-Ground Electrical Conduits

Let's talk about galvanized metal tubes. Sure, there are PVC conduits on the market, too. We, however, are looking at a sturdier electrical routing solution. The conduit run is planned first, then the anchoring saddles are fixed to the walls and ceiling, perhaps in an HVAC plant room. This heating, ventilation and air conditioning area is weighted down by pumps and fans, plus a number of chilling units. Seeing that the temperature climbs high in Melbourne, it's the contractor's job to employ the state-mandated wiring regulations and to use conduit cross-sectional areas that safely carry all of these high-current electrical wires.

Moving the Conduits Underground

That previous wiring example employs bending machines and a great deal of craftsmanship, too. What if this case study takes place underground? That's not unusual, especially in Melbourne, a city that prides itself on its clean looks. Picture either a medium-duty galvanised conduit or a heavy-duty PVC (UV stabilised) run working its way through a trench. Coloured orange and protected by concrete, plastic tubes are even replacing their metal equivalents, probably because a flexible polymer can adapt in response to an occasional groundswell or dip. Metal pipes, faced with this ground-based issue, may fracture.

Using Common Cross-Sectional Areas

A handful of low-voltage wires move across a garden to a house extension or a small shed. The 25-mm tube swings up by ninety-degrees, couples to a mains distribution switch, then it terminates at a fuse board. Communications cables follow similar procedural methodologies. Then there's the larger cables, the high-voltage electrical lines that install under street intersections and large structures. They're grouped like a row of widened tunnel openings. This is a group of 80-mm to 100-mm orange-hued conduits, all safely filled with medium to high-voltage cables.

Regulated by the AS 2053 guidelines and other relevant safety-centric directives in and around Melbourne, Australia, the electrical conduits are never congested and never sized incorrectly. Indeed, there are tables and sizing charts that ensure the process goes off without a hitch. They mandate straight runs, account for mechanical loads, and instruct the installer all about those cross-sectional area issues. Still, nothing beats a seasoned professional, a team that's trained in every aspect of this conduiting work.
