Dodgy cable wiring puts 40,000 Australian homes and businesses in danger

Over 40,000 Australian homes and businesses have been installed with potentially deadly electrical cabling. The dodgy cabling – 4000km, has been recalled and must be identified and replaced before it becomes a fire or electrocution hazard.

Sydney woman Lu Luo imported the cable from China and is facing criminal charges. The company, Infinity Cable Co. is in liquidation, leaving the sellers of the Infinity and Olsent-branded cable to foot the bill for this massive product recall. The cable has been sold as far back as 2010 in hardware chains – including Masters and Mitre 10, throughout Australia, excluding the Northern Territory.

The ‘fix it’ bill is expected to cost in excess of $80 million with Woolworths-owned hardware stores up for at least 40%; most of that being through the Masters chain. Woolworths-owned Thrifty-Link Hardware and Home Timber and Hardware also sold the cable, as did Met-cash-owned Mitre 10.

Hardware chains sold the majority of the cable – 85%, mainly to small-scale electricians and other trades. The rest was sold by electrical wholesalers. It was said to retail for around half the price of alternative cables on the market.

While good-quality cable will last decades (up to 40 years) the Infinity brand is said to become brittle after 5 years, potentially exposing live conductors, creating the risk of fire and or electrocution.

When the cable was first supplied to hardware chains and electrical wholesalers it came with papers saying that it had met Australian standards. But later testing by Fair Trading found that it did not.

Have you been affected? What should you do next?

1.  If you have had electrical wiring work carried out on your home or business between 2010-2013 contact the person who did the work to check if these cables were used.

2.  If these cables were used, the installer must come to check whether there is a risk. You should not be charged for this. The installer will not remove the cable at this time.

3.  If there is a risk, the installer will contact the supplier of the cable who will arrange for the cable to be replaced.

Voltage Optimisation | Energy Saving Technology

What is Voltage Optimisation? How does Voltage Optimisation work?

Voltage Optimisation is an energy saving technology that once installed with the main electricity supply will work to optimise and regulate the incoming power to a building, ensuring that energy savings are maximised, without compromising the voltage power that is required.

How can you save money?
The Powerstar range of Voltage Optimisation units are uniquely designed with an efficiency rating of 99.91%. Along with the main benefits of reducing electricity costs and carbon emissions, clients also benefit from reducing their maintenance costs. The standard Australian voltage supply to a building is 230V, however the average voltage emitted from the National Grid is 247V (although it can be as high as 253V). You could be paying for electricity your building doesn’t require.

Installation of a Voltage Optimisation unit at Melbourne University’s Law Building. This particular unit saved our client over $30,000 on their annual electricity bills, without making any other adjustments. The return on their investment was three years.

What’s involved?
1. Visit site – we review your building’s voltage, free of charge

2. Detailed analysis – provide you with a data report of your building’s electricity consumption

3. Provide savings – we guarantee that if your building uses more than 230V we can save you money. If the minimum savings are not achieved, we will provide payment to compensate for the difference between your actual savings and our guaranteed savings. Our warranty includes parts and labour for a 15 year period.

You can achieve more than 90% in savings…

Thermographic Scanning of Switchboards

Many Property Managers and Facility Managers understand the need for thermal imaging, but don’t truly understand what the resulting scans mean for the properties they manage.

Thermography enables us to skillfully see what cannot be seen by the naked eye. We can interpret infrared imaging to determine any areas of concern and inevitably prevent havoc. At Prolux Electrical Contractors, our electricians are trained and experienced in both qualitative and quantitative thermography, to test your switchboards for any electrical and mechanical concerns, essentially providing you piece of mind, with a detailed diagnosis of your building’s electrical health.

We can show you if anything is hotter, or colder, than it should be. We can then do something about it for you, before it becomes a very serious problem! Seeing is believing…”

What is Thermal Imaging?

Thermal Imaging is a process of viewing heat, generated from an electrical switchboard. The more power a device draws from a switchboard, or if there is a malfunctioning component in a switchboard, the more heat that is generated and will therefore be detected through a thermal image. Infrared cameras are used to capture the thermo graphic image. In the electrical industry it also call thermoscanning.

Thermal Imaging is a mandatory component of your building’s Preventative Maintenance

When any one of the following areas of concern is present in a switchboard, it can generate excess heat and stress on the board, and left undetected can cause a full or partial power outage to the building that can be very disruptive for your tenants:

• Loose terminals
• Undersized cables
• Faulty fuses or circuit breakers
• Incorrectly fitted components

How to read a Thermal Imaging Report

A switchboard’s temperature has to be matched against the ambient room’s temperature in order to be able to identify if and where there’s a potential hazard. If the switchboard’s under too much stress or it is too hot, then the internal elements may ignite, with the results being catastrophic. The darker the colour means the cooler the element or area is. The lighter the colour means the area is warmer and generally under more stress. As seen in the example shown above, ‘purple’ signals COOL and ‘yellow – white’ signals WARM – HOT, in respect to the ambient room temperature.

How much does Thermal Imaging cost?

For a 15 story building encompassing 16 switchboards (one public board per level plus one Main Switchboard), thermal imaging can cost between $1,800.00 and $2,000.00.

How often does a switchboard need a Thermal Imaging test?

Thermal imaging for all your building’s switchboards should be carried out every 12 months and more frequently if environmental conditions are influential. Many insurance companies are now making thermal imaging a condition of policy renewal.

Will there be disruption to my building’s power supply during a Thermal Imaging test?

Thermography is a non-destructive defect testing technique, which means there’s no interference to your building’s power supply during a preventative maintenance check. Switchboard thermo scanning is undertaken while the equipment is on-line and running at normal capacity. By monitoring temperatures and thermal patterns this allows for an early detection of possible faults, indicated by a rise in temperature.
