Product Description
Bell Wire 0.5mm PVC CCA 100m (White) is a basic two-core signal cable for low-voltage jobs like doorbells, chimes, and simple alarm circuits.
What it's for
This wire suits low-voltage, low-current signalling — not mains power and not data. Typical uses:
- Wired doorbell push-to-chime connections
- Basic alarm sensor wiring (reed switches, PIRs on simple circuits)
- Simple low-voltage signal runs around a home or small premises
Key specs
- Conductor: 0.5mm CCA (Copper Clad Aluminium — an aluminium core with a thin copper coating, cheaper than solid copper but with slightly higher resistance)
- Insulation: PVC, for indoor use
- Length: 100m reel
- Colour: white, to blend with most interior walls and trim
Before you buy
Because it uses a CCA conductor rather than solid copper, this wire carries a bit more resistance over distance. For short doorbell or sensor runs this is rarely an issue, but for longer cable runs or anything drawing more current, check your device's wiring guidance first — voltage drop over a long thin run can cause intermittent faults. This cable is not intended for powering CCTV cameras or IR illuminators, which need adequately rated power cabling to avoid flickering or dropout at night.

Frequently Asked Questions
What is this wire suitable for?
It's designed for low-voltage signal wiring such as doorbells and basic alarm sensor circuits, not for mains power or data cabling.
What does CCA mean and does it matter?
CCA stands for Copper Clad Aluminium — an aluminium core coated in copper. It's cheaper than solid copper but has slightly higher resistance, which matters more over long cable runs.
Can I use this to power a CCTV camera?
No. This is a low-voltage signal wire, not a power cable rated for CCTV cameras or IR illuminators, which need properly rated power cabling to avoid night-time flickering or dropout.
How long is the reel and what colour is it?
It's supplied as a 100m reel of white PVC-insulated 0.5mm wire, sized to suit most indoor domestic wiring runs.
