The Importance of Design Integrity for Substation Transformer Foundation

December 13, 2019

Pedestrians don't pay any attention to electrical transformers. Maybe that's because they're locked up behind barbed-wire fences or brick walls, for the safety of those same pedestrians, of course. They're actually interesting pieces of equipment. Filled with twin coils of wiring, step-down or step-up transformers use mutual inductance magnetic fields to perform their power transforming labours.

Pipeline Construction Process After Council Permits are Granted

December 4, 2019

Pipelines play a crucial role in every property. Be it water or crude oil, pipelines can affect the way we manage our properties and maintain the necessary supply to stay functional. And since pipelines are critical to properties, the construction of the pipelines requires necessary steps before proceeding to the grand plan.

Pole to Pit Contractor in Melbourne: What Services Do They Offer?

November 22, 2019

A conventional method of storing electrical and other related lines is by placing and attaching them on standing utility poles. This method is pretty straightforward but entails numerous compromises when it comes to the people of the neighbourhood. Sometimes, the existence of overhead cables on the utility poles can be an eyesore to our eyesight, which makes a part of a property an unpleasant view to see.  These overhead cable lines can also cause accidents; whenever a pole goes down or some live wires dangle in the middle of a flood.

Safety in Civil Underground Electrical Infrastructure Works: Choose Only VEDN Accredited Contractors

October 22, 2019

VEDN credentials are recognized throughout Victoria. With them, contractors can safely go about their duties in a trench. If someone should fail to provide the necessary accreditation documents, then that individual shouldn't be involved in civil underground engineering work. In short, the Victoria Electrical Distribution Networks (VEDN), a committee composed of local power authorities, will not give its stamp of approval to contractors who cannot demonstrate a safety-centric work history.

Depth Specification for Installation of Underground Cables in Australia

October 7, 2019

All things being equal, mains electricity cables must be installed 500mm below the ground. Then, if a consumer decides to do some digging on their own land, that hole cannot go deeper than 300mm. Of course, this fixed value only refers to someone's final-run power linkage. If the cable is carrying thousands of volts and hundreds of amperes, the mandated installation depth goes deeper.

Flowable Fill for Backfilling Trenches: What is it All About?

September 19, 2019

Of some interest to civil engineering consultants, flowable backfills have been in use for years now as void filling substances. The cementitious materials cram old tunnels and mines full of free-flowing aggregates, thus averting ground subsidence issues, cave-ins, and shaft falls. A self-compacting aggregate filler by design, it was only a matter of time before trenching services discovered this amazing backfilling substitute.

Trenching for Underground Mains: Is There a Depth Requirement?

September 6, 2019

Power distributing networks form intricate, line-heavy diagrams when they're set down on paper. Operating as step-down systems, they march out from their generating stations, head towards transmission substations, then take to the air on heavy cables. It's only after they arrive at an area substation, that's when a linesman hands off the job to a trenching service who needs to safely sink the mains cables to a pre-approved depth.

Restrict Possible Electrical Hazards Using Cable Ducts and Conduit Sealings in Substations

August 22, 2019

Consider an unthinkable situation. A storm has untapped its worst downpour while over an electrical substation. If not a storm, then a mains water line has cracked. Let's face it, electricity and water don't mix. With high-voltage electricity, that mix could be explosive. To address such potential disasters, trenching services have access to several highly effective ingress protection systems.

Underground Asset Location and Mapping: Why is This Important in an Excavation Project?

July 18, 2019

This issue doesn't cause many problems out in the open country. Correction, there might be an irrigation system or a few sporadically situated structures to map. Back in a small township, things are significantly different. Although the ground looks deceptively clear in most areas, there's probably any number of underground utilities running no more than a couple of metres below the topsoil. There can be no blind digging done here.

Protective Systems in a Trenching Project: When Are They Necessary?

July 4, 2019

As a common-sense measure, trenching protection systems are adopted when the walls of an excavated ground channel are dangerously high. But that's something of a subjective term. When is high too high? According to most nationally recognized health and safety regulations, if a trench wall rises higher than 1.5 metres (5-feet), then that soil face must be fitted with a protective system of some kind.

Why are Geotechnical Soil Reports Essential Prior to Starting Any Excavation Project?

April 4, 2019

Geotechnical soil reports are taken as ground samples. At various intervals along a route, a standard penetration method collects the samples, perhaps by driving a hollow core a meter or more into the ground. The results of the tests are then collated and formed into a detailed report.
