Application

These data cables with twisted pairs are used for interference-free transmission of data and signals over longer distances. The high transmission rate are suitable for RS 422 and RS 485 interfaces. This cable forms an integral part of supervisory control and data acquisition (SCADA) systems.

These cables are suitable for fixed installations as well as for flexing applications, for free movement without forced motion and without tensile stress in dry and moist environment.

Standard

Based on VDE 0812

Cable Construction

Bare copper stranded 7 wire conductor Conductor make-up for

0.22 mm² = 7 x 0.20 mm

0.34 mm² = 7 x 0.25 mm 0.5 mm² = 7 x 0.30 mm

Conductor resistance (loop) at 20°C

0.22 mm² = 186 Ω/km (max.)

0.34 mm² = 115 Ω/km (max.)

0.5 mm² = 78.5 Ω/km (max.)

Metal coated copper is also offered on request.

Core insulation of PE (Polyethyelene).

Core colours as per DIN 47100 (Refer table no. 2-1)

Cores stranded in pair with optimal lay-length.

Pair stranded in layers with optimal lay-length.

Aluminium backed PETP foil over the laid up pairs.Aluminium backed PETP foil over the laid up pairs.

Tinned copper braided screen, approx 85% coverage.

Special PVC outer sheath TM2, to EN 50363-4.1.

Sheath colour grey (RAL 7032).

Type …… Yv with reinforced black outer sheath suitable for outdoor application.

For underground burial, armoured version available on request.

Properties

PVC self-extinguishing and flame retardant according to EN 60332-1-2.

The twisted-pair lay-up prevents electrical unbalances within the cable and this thus effectively suppresses cross-talking effects.
