|
CONSTRUCTION: |
|
|
Conductors |
copper, multi-wire, class 5 as per PN-EN 60228 |
|
Insulation |
special softened PVC |
|
Cable core |
stranded into pairs |
|
Insulation colours |
pair No. 1: blue – red pair No. 2: grey – yellow pair No. 3: green – brown pair No. 4: white – black |
|
Central core |
pairs stranded in bundles (four pairs constitute one bundle), bundles are wrapped in a polypropylene tape marked with an ID number; bundles stranded into a central core; central core wrapped in a polyester tape |
|
Shield |
AL/PET tape, earthing conductor with a diameter of 0,5 mm2 placed under the shield |
|
Sheath |
special softened PVC, flame retardant, grey |
|
Operating temperature |
for fixed systems: -30°C to +70°C for mobile systems: -5°C to +70°C |
|
Bend radius |
min. bend radius 7,5 x cable diameter |
|
Application |
cable for sending analogue and digital signals using 10 kHz band, the cable is build for good crosstalk attenuation, cables are intended for sending digital signals with speed of up to 200 Kbit/s, cables are intended for interiors and for flexible connections inside of buildings |
|
Technical parameters |
effective capacitance at 800 Hz (with pairs > 4 may be increased by 20%) capacitance asymmetry: at 1 kHz 370 Ω at 10 kHz 130 Ω nominal wave attenuation: at 1 kHz 1,2 dB/km at 10 kHz 3 dB/km near-end crosstalk attenuation at: 10 kHz and 500 m > 60 dB |
|
Packing |
coils, drums |
