Cable Tension Wire - Insulated

Low voltage insulated cable sold either per metre or in reel quantity of 100 meters.

Conductors are braided, nickel plated copper wire and insulated with a clear PVC covering.

4mm² cable has a rating of 16amps so can have a total load of 200watts i.e. 4 x 50w lamps, 5 x 35w lamps or 10 x 20w lamps.

6mm² cable has a rating of 25amps so can have a total load of 300watts i.e. 6 x 50w lamps, 8 x 35w lamps or 15 x 20w lamps.

Suitable for use with our Low Voltage Tension Wire systems.

If you order a quantity between 1 and 100 it will be provided in one length.

Please specify if you wish for it to be cut differently.

• PVC coated conductor
• 4mm² 16Amp (loads up to 200w)
• 6mm² 25Amp (loads up to 300w)

What is the maximum length you can make the wire track? Five metres is a good length at which to start considering using more than one transformer. On longer runs an isolator can be used so that two each side of a longer run can have up 300 watts of lights. You can use a single transformer for 6-7 metres without being to concerned about voltage drop. Ten metres is possible on 6pm cables but you will see the lamps as brighter closer to the transformer.

What is the diameter of the cables without the pvc cover. The cable sizes are cubic mm sizes. The 4mm cable is 3.8mm diameter with a 0.7mm thick pvc insulation. The 6mm cable is 4.2mm diameter with a 0.7mm thick pvc insulation.

When you state the maximum length of a wire track, is this the sum of the out and return lengths? So a five metre track would only span 2.5 metres. I want to use this form of lighting in a room 6.2 metres long, placing the transformer on one wall. Is this feasible? The wires have a rating of 25 amps so that's a total load of 300 watts. If you only want 6 fixtures with 50 watt lamps this will work. If your load will be higher you will need to have a transformer at each end and an isolator connecting the two. Volt drop is an issue on longer runs but as your fittings are spaced out along the run you will only notice that the end lamp is not as bright as the first light (if you look really hard). A 6.2 metre run will require intermediate supports or it will sag quite considerably. A good quality conventional (laminated or teriodial) transformer will be required.
