MICO® Twisted

MICO® is available also twisted (in the Light Duty range) with a frequency of 20 twists per metre. This cable is a solution in fire detection systems, building management, fire telephones systems, closed circuit television, alarm systems.

MICO® twisted like any other MICC cable is available covered in L.S.F. (same colours as standard Mico®). Dimensional and electrical characteristics are listed in the central pages of this publication codes 2T1 and 2T1.5. Accessories are the same as standard 2L1 and 2L1.5 cables.

Decorative Junction Boxes

MICO® is often used in historical or monumental buildings, museums, theatres, churches and artistic sites where together with its safety characteristics is preferred for aesthetic reasons, thanks to its bare copper outer sheath that eventually reaches the typical colour of old copper and compliments itself well with wood, brick, stone or old iron. When it is not possible to penetrate the wall but the cable is surface-mounted, all the electric plant can be chosen in the same material: with this purpose some special junction boxes have been manufactured in sand-blasted brass.

Applications

MICO® structure offers the best performance in many applications:

• Fire resistant
  MICO® easily conforms to the IEC 331 test, where it is powered at its rated voltage for 3 hours at 750 °C. It is also certified with accessories under Australian test conditions reaching 1050 °C after 3 hours of examination powered at rated voltage.
• Earth wire
  Outer sheath together with earth tail seal provides a low resistive earth connection, moreover the shape of this earth causes a short circuit phase-earth for any cut of the cable permitting a fast protection by the switches.
• Explosion proof
  Mico® fitted at the ends with the ISO metric entry thread glands can be used for wiring systems in flameproof apparatus and potentially explosive atmospheres.
• Waterproof
  Outer sheath continuous and weldless together with special waterproof IP67 glands with thread ISO 228 is suitable for outdoor applications.
• Pliable
  Mico® is available in coils and is easy to bend for the quality of outer sheath copper, furthermore due to its structure can be fixed with fewer clips than other cables.
• Mechanical resistance
  MICO® can be installed without further protection because the weldless outer copper sheath filled with magnesium oxide and solid conductors offers strength against any abuse, furthermore MI cables can operate at temperatures up to 250°C indefinitely and resist for shorter periods up to 1000°C.
• Small overall diameters
  MICO® diameter is smaller than standard cable so it easily suits a lighting plant with lower impact on the overall construction.
• Resistance to corrosion
  The bare cable sheath is protected by copper oxide that forms after a short period, in instances where we may find an environment corrosive for copper, it is common practice to use L.S.F. covered cables.
• Radiation resistant
  MI cables are ideal for nuclear plants, as they show little physical deterioration from nuclear radiation.
• Long life
  Due to the components being absolutely inorganic Mico" behaviour does not decrease with age and all electrical and mechanical characteristics remain stable.
