When you inspect the wiring system in your home, VIR Cables may come to mind. They are by far the most commonly used element in house wiring systems in Sydney, as many commercial businesses rely on VIR Cables for electrical purposes. The system in question is used for low voltage cables, which are generally thin, plastic-covered cables consisting of two or more thin wires.
The main job of the VIR Cable in this system is very simple, it may carry electrical current to any required outlet with all the power being safe and secure. If there is a problem with your home wiring system, these are often related to problems within the plastic insulation around the thin copper wire(s) inside them. Problems such as leakage can be the cause of serious hazards in your home environment if not taken care of properly.
Wire insulation that has worn thin or peeled away completely may expose naked wire, allowing high voltages to enter into dangerous areas of your home where it can create potential fire hazards and in some cases electrocution. Generally speaking, the copper wire may be covered in a fine non-conducting material that when exposed to air, can sometimes cause oxidation, this is basically the insulation wearing away due to contact with the air.
What is a VIR Cable
When you talk about the cable itself, it is important to remember that VIR Cable contains several individual wires that are commonly copper in colour. Because this wiring system was developed primarily for commercial purposes, the actual cables are very heavy-duty and made from a surface combination of steel wire armouring with an inner insulation shield usually consisting of high tensile strength PVC (polyvinyl chloride) or lead sheathing.
Often there can be two or more thin insulated copper conductors inside each VIR Cables whose only purpose is to carry electrical current to different parts of your house wiring system where necessary. Obviously, if these cables need to be extended at all, additional lengths would have additional conductors added as required by the length difference. There are other types of cables available for commercial purposes such as XLPE (cross-linked polyethylene).
While these may look similar to regular PVC/Rubber VIR Cables, they have a very different purpose and could not be used in place of the regular type. This is because it is designed with special insulation that doesn’t melt when exposed to high temperatures, unlike the traditional PVC Cable.
What does VIR Stand for?
VIR cables are Vulcanised Indian Rubber electrical cables. Vulcanised refers to the process of rubber is mixed with sulphur and heated which causes the rubber to harden. Indian Rubber means that this type of cable was invented in India.
VIR cables are resistant to chemicals, oils, solvents and water giving them a longer life expectancy than other types of electrical cables. These cables are suitable for applications where there is a risk of fire, oil or chemical contamination because they have low smoke emissions when burning. VIR Cable has many advantages over PVC/Rubber electrical insulation which makes it an ideal solution for hazardous areas such as mines, chemical plants or offshore rigs.
How does a VIR Cable Work
The basic design of the VIR Cable electrical wiring is like most other cables in the way of having an inner copper conductor (s). This is surrounded by interlocking steel wire armour, which acts as protection against mechanical damage. The final part consists of outer rubber insulation, which prevents any electricity leakage or accidents from occurring. Coloured thermoplastic insulation can be used when it’s necessary to identify certain wires.
All these parts combined make up the complete system that operates within your home wiring system. Of course, there are some exceptions to this rule which allow for more than one conductor to be added into a VIR Cable, however, this would depend on its application and what voltage/current levels were required. Any potential risks or hazards involved with electrical faults could be dealt with immediately as soon as possible because problems such as those described can have serious consequences.
The best way to ensure safety is by having your home wiring system checked and tested on a regular basis. This may not only save lives but can also prevent any further damage and repair costs as well. Even with the most experienced hands, accidents can still happen, however, there are many safeguards that you could know about to avoid any potential issues.
When does a VIR Cable Need Repairing?
Whenever you notice even the slightest change in voltage levels within your home, it always pays to investigate things such as loose plug points (outlets) or switches, this may be an indication of problems with your wiring system. Other symptoms include:
- repeated tripping of circuit breakers
- flickering lights
- dimming lights
- burning smells
- excessive heat around electrical appliances
- any other unusual smells or noises.
As soon as you notice any of these problems, it is important to turn off the main circuit breaker and make contact with a licensed electrician. Sometimes even very small changes in voltage and current can lead to overheating and eventually scorching of internal wiring components due to poor insulation. This can cause overheating that may even melt the inner conductors inside your VIR Cable.
The reason for this is that when exposed to air, copper oxidises, this type of coverage provides protection against such dangers but if it melts away (due to overheating) then bare wires are exposed which results in fires and potential electrocution. Of course, while all homes have some form of surge protection, it is still important to check that this is also working and in good condition.
What are the Specifications of a VIR Cable?
VIR Cable is available with copper conductors or aluminium conductors. The size of the conductor is denoted in SWG (Standard Wire Gauge). Using an appropriate current rating, choose a VIR Cable with a conductor cross-section area that may allow sufficient electrical current to pass through it without excess voltage drop or risk of overheating.
What May Happen if VIR Cables Aren’t Repaired?
As we (hopefully) all know, electrical appliances such as those used for cooking or heating water can become extremely dangerous when exposed to high voltage/current levels. This becomes even more so when the appliance is switched on and there are already problems with your wiring system. Depending on where you live, such as whether it’s a rural area or not, long periods without power can be fatal during winter because of a lack of access to alternate heat sources or supplies of fresh drinking water.
If insulation around wiring components has been damaged enough due to overheating, then currents can still flow through faulty sections and cause potential fire hazards. It may even be the case where you see sparks and smell smoke, these are both warning signs of potentially hazardous electrical conditions which could not be ignored as such problems can cause serious injuries as well as property damage over time (if left unattended).
What Sort of Electrical Cables Repair do I Need?
There is no definitive answer to this question because you may usually require a full inspection by a licensed electrician before they can determine exactly what needs to be done. If your home has been exposed to flooding, then it is necessary for a complete rewire to take place due to the amount of damage that isn’t always visible at first glance. In addition, changes in voltage or current levels, especially where VIR cables are concerned, is usually indicative of overheating inside the wiring system.
This means that insulation around your VIR Cables has been compromised and therefore there is a possibility for electrical fires to occur (which you definitely want to avoid). If you suspect any of the above-mentioned problems with your home, then contacting a licensed electrician may be required. Great care may be taken when repairing damaged wiring systems because they contain high voltage/current levels which can cause serious injury if exposed to bare skin.
What are Electrical Fires in Electrical Wiring?
Electrical fires happen when components in a wiring system become damaged. This usually occurs due to exposure to high voltage/current levels through overheating, which can often lead to the burning of internal insulation and the formation of an electrical arc. Because electricity has a tendency to take the shortest route, this means that fire may occur at points that are normally considered safe from exposure or “close enough” for other reasons.
In addition, there have been cases where individuals have attempted their own electrical repairs with disastrous results which have led to serious injuries and even death because of incorrect use of equipment or incorrect techniques being used by the person attempting repairs. If this happens, it is also worth knowing that insurance generally doesn’t cover such incidents so you may be liable for all the associated costs.
Who Could Fix the Electrical Cables?
Electricity is dangerous, so it is advisable to leave electrical repairs for licensed electricians to handle. This way you can be sure that all codes and safety regulations may be adhered to when making any repairs or installations which also ensures that your insurance policy may still apply if something goes wrong because of damaged cables or faulty equipment being used during an installation.
The History of Vulcanised Indian Rubber Cables
Sheathed wires were the first sort of electrical cables that were used to transmit power. They could be found in workplaces, homes, and government buildings throughout Europe between 1880 and 1910. However, this method was not the most effective way to transport energy. It sparked many safety concerns. On the other hand, it was not the most efficient technique to move power, and a lot of energy was lost throughout the procedure. People began searching for a better answer and discovered VIR Cables as a result.
People quickly figured out the advantages of VIR Cables once they were discovered. As a result, they began to use VIR Cables instead of sheathed wires. We may thus observe how many buildings and other structures have been retrofitted with them as a consequence. VIR actually means Vulcanised Indian Rubber and this type of rubber insulation for an electrical circuit cable became very popular in Australia before the 1950s.
What Replaced the Vulcanised Indian Rubber Insulation Cable?
In the late 1960s, an alternative to VIR Cables emerged. This was because people got tired of dealing with the insulation, which tended to crack or burst open when exposed to high temperatures or excess moisture. They wanted something better and more reliable. They ended up using a thicker type of insulation called polyvinyl chloride (PVC), which could handle higher levels of heat compared to rubber. It is still in use today for a variety of electrical cables.
Copper conductors surrounded by PVC insulation are used for power distribution in homes all over the world. Modern cables in each circuit need to have their own independent earth cable called the earth wire, leading away from the power points. PVC cables are used for indoor wiring, while sheathed cables are often seen in outdoor settings. They are made up of rubber insulation which is surrounded by flexible steel or galvanised steel wires.
However, there was still a problem with this material – it could only handle smaller voltages and power levels. That meant that engineers had to come up with another solution to address this problem. Because of this, they decided to move towards polyethylene insulation which is seen in PVC insulated cables under the trade name of XLPE. It is because of its ability to handle higher voltages that it became popular among engineers during the early 20th century.
Vulcanised Indian Rubber Cables Should Be Removed From Buildings
If you just discovered that your home has VIR Cables or other types of antiquated electrical wiring, then it is best to get an electrician to come and take a look at them. The problem may be hazardous, not only because there could be a risk of fires or electrocution, but also due to health concerns that may arise if carbon particles (contained in VIR insulation) are released into the air.
As many people struggle to properly remove old electrical equipment, it might make more sense financially to call up a licensed electrician who can do the job instead. After all, they have experience properly handling high voltages and could be able to get the job done right
