25mm² Twisted Pair Aluminium Wire

This wire is available in a 250m roll and in 20m increments. 

Note we have a good price of 100m lengths at the moment. Lengths shorter than 250m do not come on a drum.

This wire is available on this website for the express purpose of providing cost effective wire (often below RRP) to our clients buying or owning our hydro turbines. If you are interested in purchasing this wire but are not a hydro client please contact us for a price. We reserve the right to refuse sale of this wire if the client is not also a hydro client of ours.

This wire can be used in aerial applications up to 600VDC or on ground ELV applications (in NZ) up to 120 VDC.

It is intended for long run ELV hydro applications through bush/forest and along water ways where burial or aerial protection is not practical. ELV cables only need conduit protection “as required”. This can be sleeving the cable in low cost 32mm LDPE pipe or PVC conduit to provide extra protection as may be required. 

Use our on online calculation tools to determine the cable loss on your site. Cable losses less than 10% are often acceptable on long cable runs.

It can also be used in LV applications in protective conduit subject to a COC. Speak to your electrician prior to ordering for LV applications.

For those requiring more than 3 rolls contact us for a discount and delivered price quote.

Each full roll comes with a pair of 25mm cable joiners and 2-pairs and 25mm bi-metal lugs so that you can convert to copper for connection to your: breaker, fuse, PCE, copper tails, etc. Orders by the meter do not receive the joiners and lugs. If you require additional joiners or lugs they can be purchased here.

Full rolls are bulky and heavy so cannot be sent in NZ by courier to your home address. Lengths 100m or less can be sent by courier. The web site will determine the freight price to your nearest TNL truck depot for you to collect. When ordering drums of wire do not order with other smaller items that would normally go by courier. 

If 25mm^2 per conductor is not  large enough then combine both to make 50mm^2 and run the wire twice. For larger than 50mm^2 per conductor look our other aluminium cable options.

Note: if wiring your own system in NZ, you can do so for voltages up to 120 VDC (ELV) if you have suitable knowledge and experience. For LV systems (>120 VDC) this is prescribed electrical work and it must be done by a licenced electrician.
