Building wire and cable play a crucial role in the construction of nearly every commercial, industrial, and residential property worldwide. Commonly referred to as branch circuit wiring in homes and businesses, these products facilitate the flow of electrical current to power various devices within a building or dwelling.
Construction
Conductor
The conductors, responsible for carrying the current, consist of stranded, high-conductivity plain annealed copper wires conforming to class 2 in BS 60228 and IEC 60228. Alternatively, aluminum stranded compacted conductors are also utilized.
Insulation
The cable’s rated voltage level is contingent on the dielectric strength and thickness of the insulation. Standard wiring cables employ PVC grade Type TI 1 of BS 7655 (formerly BS 6746) for insulation, suitable for a maximum continuous conductor operating temperature of 70˚C.
Characteristics
Standards
Core Identification
For cables with Single core – Red, Black, Yellow, Blue, Yellow/Green are the most commonly used colored wires
Applications
Designed for domestic wiring, this cable can be installed in fixed installations in dry or damp premises, either clipped to the surface, on trays, or in free air where the risk of mechanical damage is not a concern.
It is suitable for laying in conduit or trunking when mechanical protection is required.
Construction
The conductor is made of annealed high purity of copper, having excellent property of electrical conductivity as well as high mechanical flexibility.
PVC (Polyvinyl Chloride) is used for insulation and sheathing requirements since it is suitable for various flexible applications like high electrical, mechanical and thermal properties.
