PVC Insulated Non Sheathed Single Core Copper Wire​ The PVC Insulated Non Sheathed Single Core Copper Wire, available in 1.5mm², 2.5mm², 4mm², and 6mm², is a versatile electrical solution designed for indoor wiring in residential, commercial, and light industrial settings. Its single core construction, made from high-purity copper, ensures excellent electrical conductivity, enabling efficient power transmission with minimal energy loss—a key advantage for both low and medium current applications.​ The wire features a robust PVC insulation layer that provides reliable protection against electrical leakage, abrasion, and moisture, while operating efficiently within a temperature range of -15°C to +70°C. Unlike sheathed cables, its non-sheathed design offers greater flexibility, simplifying installation in tight spaces, conduit systems, or behind walls where maneuverability is critical. This design also reduces weight, making handling easier during setup.​ Ideal for powering lighting circuits, socket outlets, and small to medium-sized appliances, the wire’s range of sizes caters to varied load requirements: 1.5mm² and 2.5mm² for lighting and domestic appliances, 4mm² and 6mm² for higher-demand equipment like air conditioners or electric heaters. Compliance with international standards such as IEC 60228 and local regulations ensures safety and compatibility with global electrical systems.​ Its PVC insulation is flame-retardant, reducing fire risks, and the clear color coding (typically red, blue, or brown) aids in phase identification, streamlining installation and maintenance. Combining cost-effectiveness with reliable performance, this wire is a practical choice for straightforward wiring needs where a sheath is unnecessary.
