Cable for CCTV KKSPG-3-2x0.50

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

For external cabling.

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

RF cable:

• with multi-wire 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:

• power supply cores of 0.50 sq. mm cross-section
• in the common cover of light-stabilized polyethylene (outdoor installation)
