Copper-clad, mineral-insulated (MICC) cable that keeps working at 950 °C — the ultimate fire-resistant cable for emergency power and life-safety circuits.
MICC (Mineral Insulated Copper Clad) cable uses compressed magnesium oxide (MgO) as insulation inside a seamless copper tube — a construction that cannot burn, melt or emit smoke. It maintains circuit integrity at temperatures up to 950 °C for hours, which is why it is specified for fire pumps, emergency lighting, smoke extraction and fire alarm circuits in high-rise buildings, tunnels and industrial plants.
Our MICC range is type-tested by TÜV Rheinland to BS EN 60702-1:2002+A1 (certificate R 50515987, 500/750 V), available as bare copper or with an optional LSZH outer covering where the copper sheath needs corrosion protection.
| Item | Specification |
|---|---|
| Voltage rating | 500/750 V |
| Conductor | Solid copper cores, 1–19 core |
| Insulation | Compressed magnesium oxide (MgO) |
| Sheath | Seamless copper tube; optional LSZH outer covering |
| Cross-section range | 1.5 mm² – 240 mm² |
| Fire performance | Circuit integrity up to 950 °C (BS 6387 / BS 8491 equivalent) |
| Standard | BS EN 60702-1:2002+A1 |
Inorganic MgO insulation survives 950 °C — the highest fire rating available in any cable.
Copper sheath + dry MgO = service life measured in decades; moisture-sealed terminations required.
The copper tube acts as a full metallic screen — no separate screen needed.
Independently certified to BS EN 60702-1 (certificate R 50515987).
Soft fire-resistant (FR) XLPE cables with mica tape survive ~90 minutes at flame temperatures and are cheaper and easier to install. MICC survives 950 °C for hours with essentially zero degradation and 60+ year life — choose MICC for critical life-safety circuits where failure is not an option.
