  • 7/8" RF

  • hellosignal

  • XT0316

Availability:

7/8" RF Coaxial Cable


 Construction Parameters:

Inner Conductor: 9.0 mm smooth copper tube, responsible for signal transmission.

Dielectric: 22.5 mm foamed polyethylene (PE), providing insulation between the inner and outer conductors.

Outer Conductor: Nominal 24.9 mm corrugated copper tube, offering shielding and signal return path.

Jacket: 27.7 mm black polyethylene (PE) or low-smoke, halogen-free, fire-retardant PE, protecting the cable from environmental factors.



 Electrical Characteristics:


Capacitance: 76 pF/m.

Impedance: 50 Ω, a standard impedance for RF systems.

Velocity of Propagation: 0.88 (88% of the speed of light).

Peak Power Rating: 91 kW, the maximum instantaneous power the cable can handle.

RF Peak Voltage: 3.0 kV, the maximum instantaneous voltage the cable can withstand.

 

 

Insulation Resistance: >5000 MΩ·km, indicating very high insulation resistance.

Cut-off Frequency: 5.2 GHz, beyond which signal attenuation increases significantly.

Insulation Voltage: 10 kV, the maximum voltage the insulation can handle.

Jacket Spark Test Voltage: 8.0 kV, the maximum voltage the jacket can withstand.

Shielding Effectiveness: >120 dB, indicating excellent protection against external interference.



 

 Mechanical and Environmental Properties:


Minimum Single Bending Radius: 90 mm.

Minimum Repeated Bending Radius: 250 mm.

Number of Bends: 15, the number of bends the cable can endure.

Tensile Strength: 147 kg, the maximum pulling force the cable can withstand.

Operating Temperature Range: -55 to +85 °C, the temperature range in which the cable can operate effectively.



 Attenuation (20℃):


7-8 RF Coaxial Cable Attenuation(20℃)
