SFCJ-50-5

SFCJ series cable of the special structure design and advanced production technology, making the cable in the whole frequency range has excellent electrical and mechanical performance, and the high ratio of performance to price is low loss low cost solution one option. The electrical properties of the signal transmission rate up to 83%, but also has low loss, low standing wave, shielding efficiency higher characteristic. Mechanical properties, due to cable using flat ribbon weaving, make this series of cable have very strong torsional ability and good softness. Environmental resistant, the cable using resistance to environmental performance excellent raw material, make its have wear resistance, high bending life etc., using temperature for - 55 ℃~ + 85 ℃ .

Suitable for all kinds of radio frequency signal transmission equipment, and can be used as outdoor mobile parts of the radio frequency signal transmission line.

1. The inner conductor: the twisted plating silver thread. Stranded conductor is relatively soft, have better bending resistance and bending fatigue life. 2. Insulation: using low density PTFE, multilayer wrapped structure can make the cable diameter and insulating dielectric constant stability, safeguard the stability of the signal transmission. 3. Shield: the two shielding layer structure, internal and external shielding layer using silver plating copper strip weaving, this kind of structure has low loss and high shielding, and have strong torsional capacity. 4. Jacket: using the TPU sheath, make cable soft and wear-resisting.
