Applications

These cables are mainly used inside buildings, tunnels or closed areas in general, are designed and manufactured to guarantee the signal transmission even in case of fire, thus safeguarding the operation of the safety systems or of particularly critical and high speed connections.

Operating temperature

-40°C to +90°C

Minimum bending radius

10 times the outer diameter.

Armouring:
• A7 - Steel wire armour

Cable construction

Fibres

Singlemode and multimode fibres, with loose technology coating.

Structure

  • For type SLO-FR the jelly filled tube containing the fibres is reinforced with glass yarns and is wound with a flame resistant tape.
  • For type MLO-FR the jelly filled tubes containing the fibres are individually wound with a mica tape and are cabled around a central steel or FRP (fibreglass reinforced plastic) element. When necessary glass yarn is the traction element. A flame resistant tape improves fire resistance.

Inner sheath (only for A1 and A3 armoured cables)

LSZH thermoplastic compound.

Armouring

A1 Galvanized steel wire braid
A3 Corrugated steel tape
A5 Anti-rodent glass yarns

Outer sheath

LSZH thermoplastic compound.
Colour orange (other colours on request).
