Flexible Cable
Flexible cable, or flex, has finely stranded conductors that bend repeatedly without breaking, so it is used to connect appliances, luminaires, heaters and portable equipment to a fixed supply. Our range includes 3183Y and 3184Y PVC flex, LSF and LSZH flex, heat resistant flex, H0RN-F rubber cable, yellow Arctic flex, 2 core flat flex and tri-rated switchgear wire.
Choose 100m coils or cut lengths. Trade buyers get trade pricing, and in-stock flex ordered by 5pm on a weekday reaches NI and ROI sites the next working day.
How to choose the right flexible cable
Flex is not one product but a family of cables, each with a sheath and temperature rating suited to a particular job. Matching the flex to the environment and the appliance is just as important as getting the conductor size right.
Common types of flex
- PVC flex (3182Y, 3183Y, 3184Y) – general-purpose indoor flex for appliances, lamps and pendants, in 2, 3 and 4 core.
- LSF and LSZH flex – reduced smoke and fume sheathing for public buildings, escape routes and enclosed spaces.
- Heat resistant flex – for immersion heaters, storage heaters and luminaires where terminal temperatures are higher than standard PVC can handle.
- Rubber flex (H0RN-F) – tough, oil-resistant cable for site equipment, outdoor tools and harsher environments.
- Arctic flex – stays flexible in low temperatures; yellow is commonly used for 110V site equipment and blue for 230V.
- Flat flex – 2 core 0.5mm and 0.75mm for low-power lighting and small appliances.
- Tri-rated switchgear wire – single-core panel wiring for control panels and switchgear.
Sizing and ratings
Choose the conductor size from the appliance's current and the length of the lead, and confirm that the fuse or protective device suits the flex size. Check the cable's maximum operating temperature, especially near heat sources, and follow the appliance manufacturer's instructions. Current wiring regulations set out requirements for flexible cables and cords, so refer to them for anything beyond a straightforward appliance lead.
Fitting and protecting flex
Use the correct cord grip on every plug, connection unit or luminaire, and make sure the outer sheath is clamped rather than the cores. Where flex enters a metal enclosure, fit a suitable gland or grommet. For neat terminations, pair your flex with plug tops or ceiling roses, and for site extension leads see our industrial plugs.
