TPS/Flat Twin and Earth PVC/PVC Insulated Wire Cable

Flat Twin & Earth Cable

Conductor: Plain annealed copper (AS/NZS 1125)

Insulation: PVC V90

Sheath: 3V-90 Easy-tear White

Voltage: 450/750 VS

Standard: AS/NZS 5000.2

Packing Length: 100m, 500m

Normal Operating Temperature: 75°C

Core Color: Twin & Twin Active – Red & Black or Red White (Twin Active)

Twin and Earth Cable:  Twin and earth cable comprises two individually insulated current carrying conductors and an uninsulated circuit protective conductor. Twin and Earth cable is the most common cable used for domestic wiring today.

The sheath is either grey (PVC) or white for low smoke cables (OHLS).

Flat Twin and Earth:  Also known as FTE (flat twin and earth) the live and neutral conductors are individually insulated, and the Circuit Protective Conductor (CPC) or earth, is bare. Not suitable for unprotected use outside as the outer sheath materials are vulnerable to attack by UV although protective paint can provide some UV protection.

Standard metric twin and earth cable sizes are:

1mm² 1.5mm² & 2.5mm² which have solid (non-stranded) conductors
4mm², 6mm², 10mm², 16mm² and higher have stranded conductors
1.5mm² is used typically for domestic wiring circuits and 2.5mm² twin and earth is used in domestic power circuits
