APPLICATION

Cables are designed for citizen band, radio communication antenna and data transmission systems, electronics, computers, control systems, TV, for installation of radio/radar equipment.

DESIGN

INNER CONDUCTOR — copper wire or tinned copper wire.
INSULATION — polyethylene of low density; polyethylene foam.
OUTER CONDUCTOR — оbraid from copper wires; in cables SAT-50; RG-6 - the combined conductor from aluminoflex and tinned copper wires.
SHEATH — light stabilized PE or PVC.

Cables with PE sheath resist to influence of temperatures from -60°C up to +85°С; with PVC sheath - from -40˚С up to + 70˚С.
Cables resist to high (to 300 kPа) and low (to 0,67 kPа) air pressure.
Cables resist to vibration, impacts and linear loads, acoustic noise; cables resist to the raised humidity, hoarfrost, solar radiation, a hydrochloric fog, mold fungi, mineral oils, salty water, gasoline, dust.
Average service life of cables with PE sheath is 12 years; with PVC sheath is 8 years.
