500 Semi-Finished Trunk Cable Aluminum Tube Trunk Cable for feeder and distribution
Quick Details:
Product description:
The inner conductor is high quality copper clad aluminum (CCA), dielectric core is produced by insulating grade virgin polyethylene, it is tightly covered by solid aluminum tube. Medium density PE is used as jacket material.
Applications:
P3 500JCA 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.
