Product Description
UniStrand 3183Y is a 3 core, 2.5mm² flexible mains cable supplied on a 100m reel. It's rated 300/500V, carries flexible Class 5 copper conductors to BS EN 60228, and is built with PVC insulation and a black PVC outer sheath.
On a CCTV or low-voltage install, this cable belongs on the mains side — powering the DVR/NVR cabinet, a PoE switch's power supply, or a rack socket — rather than running out to individual cameras. Keep it in its own run, away from data and coax cabling, so mains and low-voltage signals don't share a path unnecessarily.

Where it's used
This is general-purpose flexible mains cable — suited to appliances, power tools, office equipment and portable devices, plus extension leads and temporary power connections. For CCTV work, that translates to feeding the equipment that runs your recorder and switches, not the camera drops themselves.
Before you buy
Check you actually need the full 2.5mm² core size and 100m length for the job — this is a bulk trade reel, not a made-up lead, so you'll need to terminate it yourself.
Frequently Asked Questions

It's a mains cable rated 300/500V, so it's for feeding equipment like your DVR/NVR or PoE switch power supply, not for wiring individual cameras.
What's the current rating?
Approximately 25A, with a 300/500V voltage rating.
Does it come pre-terminated with plugs?
No — it's supplied as a 100 metre reel of flexible cable, so you'll need to terminate and install it yourself.
What temperature range can it handle?
It's rated for an operating temperature of approximately +5°C to +70°C, which suits typical indoor installation environments.
