Quick Details:
• Aluminum Tube Trunk Cable PIII 565JCAM
• Seamless aluminum tube as outer conductor
• Patented technology
• High quality PE outer jacket
• Asphalt or flooding compound is available
Product description:
The aluminum tube trunk cable with outstanding electrical performance and excellent bending radius.
Inner conductor is high quality copper clad aluminum (CCA), dielectric core is made of insulating grade virgin polyethylene; seamless aluminum tube as shield, and medium density PE is used for jacket material. Messenger is made of zinc coated (galvanized) carbon steel wire. The jacketed messenger is connected to the trunk cable member with a web.
Applications:
P3 565 JCA trunk cable is used as main cable and distribution cable for CATV network, it is applicable in transmission of single and duplex analog signals and as well as duplex digital signals. And the trunk cable is also widely used in HFC duplex transmission network.
