Coaxial cable FinMark

FinMark coaxial cable of Series 6 with additional current-carrying conductors

1
Description

FinMark coaxial cable of Series 6 with additional current-carrying conductors is used for the transmission of CATV high-frequency signal or other types of signals. The main application areas of such cable are  cable TV systems for remote power feeding where local power connection is impossible or is very difficult. This type of cable is also used for video surveillance systems , for direct power supply to the surveillance camera , to remote TV modulators, amplifiers , etc.

FinMark coaxial cable F690B- 2 * 0.75power / F690Bcu- 2 * 0.75power

F690B-2*0.75power / F690Bcu-2*0.75power - a cross-sectional view of the cable has a " 8 " shape . One part of the “8” has center conductor with  shielded layer of foil and 90 %  braide  filling which are divided  by physically foamed dielectric. The second part of the" eight" has two copper conductors , each of which is covered with its own sheath. If necessary,the  part of the copper conductors may be easily separated from the overall cable body. Conductors have different colors  (red, black) for identification. For the convenience of  cable termination, there is a special thread for the longitudinal jacket opening. Jacket  color is black.
