Leading UK fire resistant cable manufacturers
At Custom Designed Cables, we design and manufacture high-performance fire resistant cables for safety-critical environments where maintaining power, control, and communication systems during a fire is essential.
As experienced fire resistant cable manufacturers, we work closely with OEMs, contractors, system designers and engineers to develop bespoke cable solutions that meet the demanding requirements of modern infrastructure projects. Whether you’re designing a new installation or upgrading an existing system, our fire-resistant cable solutions are engineered to deliver reliability, safety and compliance when it matters most.
What are fire resistant cables?
A fire resistant electrical cable is specifically designed to continue operating for a defined period when exposed to fire. Unlike standard cables, which may quickly fail when subjected to extreme temperatures, fire resistant cables help maintain critical circuits that support life safety systems and emergency operations.
These cables play a vital role in ensuring essential services remain operational during an emergency, helping to protect building occupants, support evacuation procedures and reduce the risk of system failure.
Many fire resistant cable designs utilise specialised insulation systems and Low Smoke Zero Halogen (LSZH) sheath materials. LSZH compounds minimise smoke generation and eliminate the release of corrosive halogen gases, helping to improve visibility and reduce potential harm to people and equipment during a fire.
Why fire resistant electrical cables matter
Fire safety regulations and building standards continue to evolve, placing greater emphasis on the performance of electrical systems in emergency situations.
When conventional PVC cables are exposed to fire, they can produce dense smoke and potentially harmful gases that may hinder evacuation efforts and damage sensitive equipment.
In contrast, fire resistant electrical cables are designed to:
- Maintain circuit integrity during fire conditions
- Support life safety systems and emergency services
- Reduce smoke emissions
- Eliminate halogen gas release when using LSZH materials
- Improve visibility during evacuation
- Help meet project-specific fire safety requirements
- Minimise downtime and operational disruption
For many public buildings and critical infrastructure projects, the use of fire-resistant cabling is a fundamental part of the overall fire protection strategy.
