Cable for CCTV KVK-3 f 2x0.50

Combined cables intended for the transmission of television signals in video surveillance systems with simultaneous connection of power and/or transmit control signals.

For the inner strip.

It consists of a radio frequency cable and power supply wires, united under a single sheath.

RF cable:

• with solid copper inner conductor
• with insulation of foamed polyethylene
• with the external conductor in the form of a braid of copper wire

Cores power and a common cable sheath:

• veins supply a cross section of 0.50 sq. mm
• in the common sheath of PVC compound (for internal installation)

Features:

• Brand radiocable - RK 75-3-32
• Inner conductor - 1x0. 60 mm
• Insulation diameter - 2.7 mm
• The attenuation coefficient at f=6 MHz and 2.9 dB/100 m
• Outer cable diameter - 10 mm
• Cable weight is 69.5 g/m
• Material outer sheath - PVC
• Leads electric resistance to DC current at 20 °C and length 1 km, not more of 40.5 Ohm/km

The electrical characteristics of radiocable:

• Impedance - 75 Ohm
• Electric cable capacitance - 56 pF/m
• Coefficient of shortening of the wave length of 1.22
• The coupling resistance is 110 mOhm/m
• The speed of propagation of the wavelength - 82%

Attenuation coefficient:

Operating conditions - from -50°C to + 70°C.

Resistant to high humidity 98% at temperatures up to 35°C, under conditions of installation bending or minus 15°C.

Resistant to bends (not less than 10 bends at an angle of +/-90° if the radius of the bend, equal to ten maximal external diameter of the cable).

The service life of the cables is 25 years.
