2-48 Pairs Individual Screen Armoured Instrument Cable application:
insutrumention cable Individual & Overall Screened Steel Wire Armored/ SWA Pairs is used in data processing and process control. Suitable for fixed
installations in damp locations and open spaces. The electrostatic screen protects against outer interference fields.
1. Desing: LSZH (Low Smoke Zero Halogen) Instrumentation cable consisting of bare copper conductors, black & white , twisted pairs or black,white &
red twisted triples with continuous number sequence.Cables are manufactured strictly in accordance of UL as well as relevant Australian Standards.
2. Voltage rating :Rated Voltage Max. 300V a.c; Nominal Voltage A.C/D.C 110/150V, Test Voltage In process spark test – 4500V and AC withstand
voltage test – 1500V, TECHNICAL DATA 0.5mm 1.5mm
3.Maximum Capacitance
Conductor to Conductor 145pF/m 200pF/m, Conductor to Screen 240pF/m 300pF/m, Maximum Conductor Resistance @ 20 C 38.4Ω/km 13.8Ω/km,
Insulation Resistance @ 20 C 40MΩ/km 140MΩ/km, Cross Talk Attentuation Between Pairs @ 1kHz 300Ω 150Ω
Inductance @ 1kHz 1.00mH/km 0.95mH/km, L/R Ratio @ 1kHz 13.7µH/Ω 36.5µH/Ω
4.Operating Temperature
Minimum continuous operating temperature -25°C,75°C, 90°C, Minimum short circuit temperature 160°C (for 5 sec)
5. Bending Radius: The following minimum bending radius should be observed to ensure operating reliability
unarmoured: 9 x cable outer diameter (during installation) 6 x cable outer diameter (after installation)
Armoured: 18 x cable outer diameter (during installation) 12 x cable outer diameter (after installation)
6.Tensile strength
Cable maximum pulling tension (approximate) is limited to 65-70 N/mm² of the total cross-sectional area ofconductor.
7.Example: 3pairs 1.5 total cross sectional area 3x 2×1.5=9mm² 9mm² x 70Nmm² =630N (0.63kn)
For pulling by armour, the pulling tension should be limited to 130 N/mm² of the total cross-sectional of steel wire
