Multipair

  • PE/IS/OS/HIPK/SWA/PVC
  • XLPE/IS/OS/HIPK/SWA/LSZH
     

Applications

This is an alternative to lead sheath and can be used in cable tray, conduit or direct burial to connect electrical instrumentation and communication circuits in industrial process controls. This protection has lower weight and smaller diameter compared to lead sheath.
Excellent protection against corrosion, humidity, in petrochemical plants.

Temperature range

-20 °C to +80 °C (for general use);
-40 °C to +90 °C (on request).

Minimum bending radius

20 times the outer diameter.

Applicable Standards

BS 5308 or
EN 50288-7
Basic design   
IEC 60332-1 Flame retardant
IEC 60754-1 Halogen free properties (only for LSZH cables)
IEC 61034-2 Low smoke emission (only for LSZH cables)

Available on request

Tinned conductors.
Single triad or multitriads.
Galvanized steel tape armour (GSTA).
Different insulation and sheath colours.
Sheath materials can be provided for excellent water, oil, hydrocarbons, UV resistance or other special performance.
Fire retardant to IEC 60332-3 cat. C or A.

Cable construction

Conductors

Plain annealed electrolytic copper wire according to EN 60228 class 1(U) solid, class 2 (R) stranded, class 5 (F) flexible.

Insulation

PVC, PE, XLPE or LSZH thermoplastic material.

Twisting

The insulated cores shall be twisted in pairs/triads for a good reduction of the electromagnetic noise.

Individual screen

Aluminium/polyester tape, coverage >100%, aluminium in contact with tinned copper drain wire.

Cabling

The pairs/triads are cabled with suitable non hygroscopic fillers (when necessary) and wrapped with polyester tape if required

Overall screen

Aluminium/polyester tape, coverage >100%, aluminium in contact with tinned copper drain wire.

Hi-Pack protection

Aluminium tape coated with a protective plastic coating, longitudinally applied, bonded to black extruded bedding of High Density Polyethylene compound plus an additional Polyamide-Polypropylene special thermoplastic alloy.

Armour

Single layer of galvanized steel wires (SWA).

Outer sheath

PVC or LSZH thermoplastic material.
