Vir Cable Full Form - Vulcanized Indian Rubber Cable
vir cable full form
VIR Cable stands for Vulcanized Indian Rubber Cable. It is a type of electrical cable insulated with vulcanized rubber. VIR cables were commonly used in electrical wiring before the advent of modern insulating materials.
Construction of VIR Cable
VIR cables consist of copper or aluminum conductors insulated with vulcanized rubber. The rubber is treated with sulfur to improve its durability, heat resistance, and electrical properties. The cable may also have a protective sheath for added safety.
Applications and Limitations
VIR cables were widely used in domestic and industrial wiring during the early to mid-20th century. They are known for their flexibility and reliability. However, they have been largely replaced by PVC and XLPE cables due to better performance and safety.
One major limitation of VIR cables is their susceptibility to aging, moisture, and heat. Over time, the rubber insulation can degrade, leading to potential safety hazards. Modern cables offer superior longevity and safety features.
Despite being outdated, VIR cables are still found in some old buildings. When encountered, they should be inspected and replaced to ensure electrical safety and compliance with current standards.
