Finolex 3-Core Flexible Wire, 100m Coil

Finolex 3-Core Flexible Copper Cable Wire is available in 1.5 Sq.mm, 2.5 Sq.mm, and 4 Sq.mm variants, each in a 100-metre coil, rated to 1100V and manufactured to IS-694 standards. All three variants use multi-strand electrolytic grade bare copper conductors across three colour-coded cores – Phase, Neutral, and Earth – in a flame retardant (FR) PVC jet black outer sheath that is self-extinguishing and rated to 1100V. The multi-strand construction gives the cable high flexibility for routing through conduits and tight bends without kinking or conductor breakage.
Choose the variant based on the current load of your circuit: 1.5 Sq.mm (13A) for light circuits and smaller appliances, 2.5 Sq.mm (20A) for air conditioners, geysers, and pumps, and 4 Sq.mm (27A) for high-draw industrial equipment, large motors, and main distribution feeds. Using an undersized cable on a high-current circuit causes the cable to run warm, degrades insulation over time, and increases fire risk – always match the cable size to the circuit load.

Key Features

Three variants – 1.5, 2.5, and 4 Sq.mm: Select the correct gauge for your circuit load – 13A, 20A, and 27A respectively

Electrolytic grade copper – multi-strand: Low power loss, high conductivity, and flexibility through conduit bends without conductor breakage

3-core – Phase, Neutral, Earth: Three colour-coded cores satisfy standard residential and industrial earthing requirements in a single cable

FR PVC sheath – 1100V rated: Self-extinguishing jet black outer jacket limits fire spread – manufactured to IS-694

Recommended Applications

Where Finolex 3-Core Flexible Cable fits best

Air conditioners – 1.5 to 2 ton (2.5 Sq.mm): Dedicated 3-core circuit from the distribution board to AC units – the 20A rating handles sustained compressor load

Geysers and water heaters (2.5 Sq.mm): 2kW-3kW geysers require a dedicated 3-core earthed circuit – correctly rated for the load

Water pumps and motors (2.5 or 4 Sq.mm): Sub-surface pumps, irrigation pumps, and workshop machinery – select gauge based on motor current draw

Large motors and industrial equipment (4 Sq.mm): High-draw industrial circuits requiring up to 27A continuous current capacity

Distribution board mains feed (4 Sq.mm): Main incoming cable from meter to distribution board in residential and light commercial installations

Light circuits and general power points (1.5 Sq.mm): Fans, lighting circuits, and standard power points up to 1.5kW
