Welded Aluminum Trunk Cable With Messenger QR320 Trunk Cables for CATV
Quick Details:
• QR320 Welded Alumium Trunk Cable with Messenger
• Welded aluminum tape as outer conductor
• High quality PE outer jacket
• Asphalt or flooding compound is available
Product description:
Inner conductor is high quality copper clad aluminum (CCA).Dielectric core is made of insulating grade virgin polyethylene; RF welded aluminum sheet 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:
QR320 JCAM trunk cable’s outer conductor is high quality electric aluminum sheet, this 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.
