The 16SDI-B20 is a 16mm² black single-core double insulated cable, supplied in a 20 metre cut — perfect for when you need more than a short run, but not enough to justify a full drum. Commonly used in fixed wiring applications like submains, earthing, and power distribution, it’s suitable for residential, commercial, and industrial installations.
Built with a stranded copper conductor and dual-layer PVC insulation, the cable is easy to handle and install through conduit or protected routes. It’s typically supplied by Prysmian or Electra, two of the industry’s most trusted names. On occasion, other compliant brands such as Apec, Advance, or Olex may be used based on availability — all meeting AS/NZS wiring standards.

Q: Where is this cable typically used?
A: It’s ideal for submains, earthing, and power distribution in protected wiring setups.
Q: Can I choose the cable brand?
A: Prysmian or Electra is normally supplied. Alternate brands are rarely used and always compliant.
