Damaged UV Wiring & Cable Repair Service

Electrical defect notices are given out mostly by Ausgrid and Endeavour Energy when there are issues with someone’s electrical systems. These require a level 2 electrician to be contracted as soon as possible to correctly solve the issues on the notice. Additionally, the tasks must be completed soon because the property’s electricity will be cut off after 30 days.

With regards to UV damaged cables and defect notices, they are given out due to their immediate risk. The cables connected to the main switchboard or meter and the private power pole of a property can experience a lot of exposure to UV. With cables having too much exposure to UV it can severely damage them. The UV rays will negatively affect the wires’ insulation and sheathing if they are not designed to handle it. As a result, the cabling’s insulation will crack, therefore will lead to the wire underneath to expose.

There are serious health and electrical risks when a wire’s insulation has been removed because the open wire is revealed. Short circuit failures, electrocution, electrical fires and alike can occur when the open wire is present, especially if UV is still affecting it. It is, therefore, really important to call for a licensed level 2 electrical contractor to solve the issue quickly. If the dilemma of a damaged UV wire is prolonged it can lead to complications, injuries and fatal accidents.

As Australia has higher UV levels, cables are designed to be specifically installed to withstand the country’s larger UV amounts. The UV resistance applied to the wires is important to ensure that the wires can last for a longer time. That is why cables are made with PVC due to being one of the most resistant polymers out there. These are considered to be really great at resisting the UV from contacting with the wires.

PVC with UV present with form a brown residue which is visible to strengthen the wire. However, the cable will be more prone in the first two years of UV exposure to become brittle and cracked. To revert this, there are two methods to take to ensure that the wire’s insulation remains strong to withhold the UV:

• Carbon Black – the YV rays are absorbed to ensure that the polymer structure does not take further damage. To protect the cable, it should be made of 2% carbon black, however, 0.5% is still beneficial. Being regarded as the best UV stabilisation method for PVC these are important for protecting the wires from UV rays.
• Titanium Dioxide – this type of white pigment is adjustable, meaning it can be included with many different materials. Not as strong as carbon black, 1.5% of this material will help the PVC cable from being ruined by UV rays.

Overall, black PVC cables are best suited for the Australian environment due to their design and material makeup. They can withstand UV rays greatly which will protect the cables from being damaged and exposing the wire.
