ПРПВМ Cables for telephone and radio communication, paired with copper conductor, with PE insulation and PVC sheath Direct burial, duct-work, external wall
CONDUCTOR – soft copper wire with nominal diameter 0,8, 0,9 mm and 1,2 mm.
INSULATION - polyethylene.
SHEATH - sheath from light stabilized polyethylene for a cable ПРППМ and lightheat-resistant plastic compound for a cable ПРПВМ covers two parallel insulated conductors.
TECHNICAL DATA
DC conductor resistance for 1 km of cable at the temperature +20˚С for conductor diameter:
0,8 mm - 36,0 Ohm;
0,9 mm - 28,4 Ohm;
1,2 mm - 16,0 Ohm.
Electric resistance of insulation between the wires for 1 km of cable at the temperature +20˚С is not less than 10000 МОhм.
Operational temperature for a cable ПРППМ is from -60˚С up to +50˚С; for a cable ПРПВМ - from-40˚С up to +60˚С.
Cables resist to air humidity up to 98 % at the temperature up to +35˚С.
Permissible temperature for installation of cables should not be below-10˚С and bending radius not less than 10 times the thickness of the cable.
Cables are designed for laying at soil, duct-works, external walls.
The delivery length is not less than 500 meters, 250m and more cable pieces are possible to deliver but not more than 15% of total length of batch.
Service life of cables is not less than 10 years.
