Mineral Insulated Copper Cable (MICC)

Home Product Mineral Insulated Copper Cable (MICC)


MICC cable is totally Inorganic and Silicone free. It consists of multiple copper conductors (cores), highly compressed magnesium oxide (insulation) and an outer copper sheath, thats just 2 elements.

This unique composition has an outer melting point of 1083˚C (the melting point of copper) and ultimately 2800˚C for the insulation (magnesium oxide). Note that the internal load carrying cores are protected inside the magnesium oxide insulation.

This allows MICC cable to safely carry a load in temperatures in excess of 1000˚C making it a TRUE fire survival cable. MICC cable is water and oil resistant, can carry greater current ratings, require no conduit for mechanical or vermin protection, UV and radiation resistant and can last in excess of 50 years.

WREXHAM cables meet the following standards:

  • British fire performance standards BS EN 50200 PH120 Enhanced demands 2 hours fire resistance at 850˚C.
  • BS 6387 category C, W & Z demands that cables perform safely for 3 hours at 950˚C. All 3 tests performed using the same cable sample.
