What is Black Electric Ducting and How Does it Work?

Ducting is a protective pipe designed to house and shield underground cables for services such as electricity, water, gas, or telecoms. It prevents accidental damage and ensures future access for maintenance or upgrades.

Our black electric ducting is specifically designed for low-voltage electricity applications and features:

  • A corrugated exterior for added strength and flexibility
  • A smooth internal bore to reduce cable snagging
  • Colour coding to indicate its use and comply with UK standards

This makes it suitable for use beneath driveways, footpaths, roads, and landscaped areas in both short and long cable runs.

Frequently Asked Questions

What is black electric ducting used for?
Black electric ducting is used to house and protect underground low-voltage electric cables. It's commonly installed in domestic, commercial, and industrial projects for electricity supply, street lighting, and traffic signals. The ducting ensures cable safety, allows for easy maintenance, and complies with UK utility colour coding standards.

Is black ducting suitable for high-voltage cables?
In some regions, high-voltage cables may be run through red or black ducting, but always check local regulations. Black ducting is primarily used for low-voltage electrical installations, such as residential supply or lighting.

What sizes does electric ducting come in?
Here at Cotterill Civils we supply a wide range of ducting sizes, including:

- 125/148mm ducting
- 94/110mm ducting
- 125/145mm ducting

Larger sizes are also available upon request.

Why is ducting colour-coded?
Ducting is colour-coded to help identify the type of utility it protects and improves safety on site. For example:

- Black: Electricity (low voltage)
- Yellow: Gas (vented)
- Orange: Street lighting & traffic signals
- Green: CCTV and fibre optics
- Purple: Motorway communications
- Blue: Water

Always confirm colour requirements with your local utility provider.

Can I use black ducting for street lighting?
Yes, black electric ducting can be used for street lighting applications. In some areas, orange is used instead, especially for traffic signal cables, so always check your project's specifications before installation.
