After polyethylene and polypropylene, polyvinyl chloride (PVC) is the third mass produced synthetic plastic polymer. There are two basic forms of PVC, rigid and flexible. While rigid form is prominently used in the production of pipes, bottles, packaging and cards, insulated electrical cables, signage, imitation leather and inflatable products are produced from PVC mixed with plasticizers.
PVC cables are versatile, high in tensile strength, flexible, good conductors and easy to joint. Due its dynamic properties these wires are commonly used for home appliances, wiring of circuits, house wiring, power supply solutions, instruments, submarines, mining operations, ship wiring etc.
Some of the major advantages of using PVC wires are:
- The compact conductors reduce AC loss due to the proximity or skin effect.
- They bear stresses related to thermo-mechanics during constant normal and short circuit conditions.
- These cables have resistance against the chemical or electrolytic corrosion.
- They are also unaffected by moisture.
- These wires have great fire resisting qualities due to their resilient sheath.
- They are unaffected by vibrations.
These cables reduce dielectric losses and internal stress in electrical applications.
Demand for the electrical cables is ever increasing. Electrification and house constructions is on the rise. As the old wiring ages, it has to be replaced by new and latest ones for proper functioning of electrical applications and appliances. Considering the requirements of market, PVC cables are an ideal solution. They are robust, cost effective, have high conductivity and can provide insulation against any electrical faults.
In addition, durability is another factor that works in the favor of these wires. They are durable, which means that you do not have to worry about changing your electrical cables anytime soon after the installation.
