Polyvinyl Chloride is what PVC in a PVC cable stands for. Generally, any electric wire that has a Polyvinyl Chloride jacket or insulation is referred to as a PVC cable. They are widely used because of their high chemical, water, and heat resistance while being extremely flexible and sturdy. However, there are a few more reasons that you &#; a property owner- should consider investing in PVC insulated cables. Scroll down to know more about PVC cable benefits:

Unlike many other wires, a PVC cable is flexible and hence, easy to bend into any convenient shape. They can also be welded, which is why they are available in an array of sizes and pre-sizes shapes, too. Their light weight enables easy maintenance.
With the world becoming more conscious about environmental pollution, so have PVC cable manufacturers. These cables now have a low lead and heavy metal content, less hydrogen chloride and are non-toxic.
A major benefit of a PVC sheath is that it has the ability to extinguish sparks or flames. So, in essence, if the source of a fire has been dealt with, the PVC insulated cable will stop burning automatically.
PVC insulated cables have great dielectric strength, meaning they can sustain a high electric field before their insulating properties begin to diminish. This makes them resistant to extreme temperatures.
Now that you know PVC cable benefits, we are sure it is something that you will consider. However, with competitive options like XLPE cables, we know it might be difficult to make a choice. We have written an article with the differences between these two wires; check it out here for more clarity.

If PVC cables are what you have decided to go with, it is essential to choose a reputed brand that is trusted by millions. But, which one?
PVC (Polyvinyl chloride) is widely used in electrical cable construction for insulation, bedding and sheathing. It was the s when PVC started to replace rubber insulated and sheathed cables in general household wiring due to its ease of processing. PVC is cost-effective and also has excellent ageing properties and typically exceeds a 25 to 30 year service life.
It&#;s considered to be one of the most versatile of the common thermoplastics due to the fact that its properties can be easily modified - although PVC is inherently hard and rigid it is easily modified with plasticizers, stabilizers, lubricants and various other ingredients and fillers that aid processing and enhance various properties. It is also easy to process and recycle when used as a thermoplastic type.
Cable with a PVC insulation or sheathing is flame retardant, which is an important consideration for electric cables in most applications. PVC can be made resistant to a wide range of chemicals including oils, acids and alkalis, and is tough, durable and resistant to abrasion. The addition of various additives can improve its temperature range, typically from -40 to 105°C, as well as the resistance to sunlight, reduced smoke emission and improved water resistance.
As an insulation material cables often come down to a choice between XLPE vs PVC - between a thermoplastic and a thermoset material. There are thermoset versions of PVC which are cross-linked, typically with electron beam technology but they are more expensive to use and so when specified they are typically in high-spec applications in industries such as defence and automotive. The thermoset or cross-linked PVC has improved temperature resistance, is tougher, and has a better dielectric strength, which means that a thinner coating or insulation layer can be applied making the overall cable dimension smaller.
