75 ohm Aluminum Tube Trunk Cables with Asphalt 412 without
Messenger CATV Trunk Cable 412JCA
Quick Details:
• Aluminum Tube Trunk Cable 412JCA
• Seamless aluminum tube as outer conductor
• Patented technology
• Over 20 years of experience
• High quality PE outer jacket
• Asphalt or flooding compound is available
Product description:
Both electrical and mechanical performance of the trunk cable meet
with TFC trunk cable standard. Medium density PE is used as jacket material. asphalt or
flooded compound is added before jacket extrusion for moisture
prevention.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.
Applications:
P3 412JCASS 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.
