1. Residential & Commercial Wiring
Lighting Circuits: Used for indoor lighting in concealed or surface-mounted installations.
Power Outlets: Suitable for connecting sockets (common sizes: 1.5mm² for lighting, 2.5mm² for general outlets).
High-Power Appliances: Larger cross-sectional areas (e.g., 4mm² or above) are required for air conditioners, water heaters, etc.
2. Electrical Distribution Systems
Acts as branch or main wiring from distribution boards to switches and outlets.
3. Industrial Equipment
Powers fixed machinery but requires additional mechanical protection (e.g., conduits or cable trays).
4. Temporary Installations
Can be used for short-term fixed wiring but should not be exposed to outdoor or damp environments.
Advantages
Good Insulation: PVC insulation provides resistance to voltage, acids, and alkalis.
Cost-Effective: More economical than multi-core cables.
Easy Installation: Moderate rigidity makes it suitable for conduits and fixed wiring.
