CONSTRUCTION:

Conductors

copper, multi-wire, class 2 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 polyester tape marked with an ID number; bundles stranded into a central core

Shield

AL/PET tape, earthing zinc-coated single-wire conductor placed under the shield

Heavy duty sheath

special softened PVC, flame retardant, grey or, on special request, in black UV resistant sheath

Operating temperature

-30°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 placing in interiors and directly in soil, cables manufactured on special request, with black sheath, may be

placed outside or directly in soil

Technical parameters

conductor loop resistance at 20°C: 73,6 Ω/km effective capacitance: 4 may be increased by 20%) capacitance asymmetry:

near-end crosstalk attenuation at 10 kHz and 500 m > 60 dB

Packing

coils, drums
