Â
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
Â
Â
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.
Â
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.
