MICC (Mineral Insulated Copper Clad) Cable System

The standard range of MICC (Mineral Insulated Copper Clad) Cable provides the ideal solution for almost all electrical circuits in the low voltage category.

Two voltage grades—500 and 750 volts—are available with conductors from 1mm² giving current ratings up to 1000 amps. A full range of complementary accessories and tools provides a complete wiring system.

Construction

With a basis in organic construction of a copper sheath and conductors, together with a mineral insulant, the cable provides a unique combination of dependability, versatility and permanence.

This construction, with the melting points of 1083°C and 2800°C for the copper and the insulant respectively, provides the unsurpassed Fire Survival properties which enable the cable to continue to carry current at temperatures in excess of 1000°C.

Benefits

MICC survives the fire test requirements for enhanced grade cables as defined in BS 5839: part 1: 2002.

Peace of mind from the third party (LPCB) approval for categories C, W and Z in BS 6387: 1994.

Also attains categories C, W and Z of BS 6387: 1994 with one single cable sample.

Light Duty Cables (500V)

These cables are rated at 500V and are suitable for use where the voltage between the conductor and sheath and between conductors does not exceed 500V r.m.s. a.c. or 500V d.c.

Seals And Insulators

A seal is normally required at each end of a MICC Cable to provide a means of electrical connection.

Heavy Duty Cables (750V)

These cables are rated at 750V and are suitable for use where the voltage between the conductor and sheath and between conductors does not exceed 750V r.m.s. a.c. or 750V d.c.

Cable Fixings

To secure MICC Cable, far fewer fixings are required in comparison with other cable types.
