CATV Trunk Cable For Signal Transmission QR500 without
Messenger Welded Aluminum Tube Cable
Quick Details:
• QR500 JCA Welded Alumium Trunk Cable
• Welded aluminum tape as outer conductor
• High quality PE outer jacket
• Asphalt or flooding compound is available
Product description:
The inner conductor is high quality copper clad aluminum (CCA),
dielectric core is produced by insulating grade virgin
polyethylene, welded aluminum sheet as shield. Medium density PE is
used as jacket material.
Applications:
QR500JCA trunk cable is used as main cable and distribution cable
for CATV network, such as base station and equipment cabinets. It
is applicable in transmission of single and duplex analog signals
and as well as duplex digital signals. The trunk cable is also
widely used in HFC duplex transmission network.
