RG179(SFF-75-1.5)

The RG series is a flexible cable with a high density silver-plated round copper wire braided structure for the outer conductors. Because the shield is close to 95% coverage, the cable has good shielding performance, so that it has a higher frequency band and good electrical performance indicators. Electrical performance, high frequency of use, voltage station ratio is small, shielding efficiency is high.

In terms of mechanical properties, the outer conductor woven with high-density silver-plated round copper wire makes the cable more curved and formed. Environmental resistance, due to the characteristics of the cable, external conductors and insulation parts of the raw materials, determines the environmental adaptability of the cable is very strong (-65 degrees C to 165 degrees C), corrosion resistance, anti-mold, but different outer sheath materials also determine that the cable has different environmental adaptability.

Electrical and Environmental Performance

It is mainly used in various instruments and equipments that need to transmit radio frequency signals.

1. Inner conductor: silver-plated copper wire or silver-plated copper-plated steel wire.

2. Insulation: solid PTFE, transmission rate: about 70%.

3. External conductor: high density silver-plated round copper wire braided structure. The coverage of 95% of the shield makes the cable have good shielding performance, but also reduces the loss of the external conductor of the cable, making the use of the frequency band and in the full frequency band better electrical performance indicators.

4. Sheath: customized according to customer requirements.
