Unlike standard communication cables, fire resistant coaxial cables are purpose-built to continue functioning during fire emergencies. Let’s explore the materials and engineering that make this possible.
| Component | Material | Function |
|---|---|---|
| Conductor | Solid copper | Stable signal transmission |
| Dielectric | Foamed PE or ceramic | Maintains structure under heat |
| Shielding | Tinned copper braid | EMI protection, heat tolerant |
| Fire Barrier | Mica tape | Flame barrier maintaining signal circuit |
| Sheath | LSZH or silicone | Non-toxic, smoke-suppressing, durable |
Maintain impedance stability even when exposed to 800–950°C
Resist fire, mechanical stress, and water simultaneously
Prevent toxic gas emissions during combustion
Comply with safety regulations in tunnels, metro lines, hospitals
Our fire resistant coaxial cables are manufactured with strict quality control and full compliance to BS 6387 (CWZ). Whether it’s for tunnel CCTV or emergency audio systems, our products ensure that signal delivery never fails, even when everything else does.
