The trunk cable has excellent electrical performance and outstanding transmission reliabilities. Frequency is from 5MHz to 1000MHz, it provides reliable transmission and anti-interference effectiveness for duplex transmission network.
To withstand rigors of environmental elements, jacketed burial cable or jacketed flooded cable isavailable; asphalt is added between outer conductor and jacket to prevent damages from moisture and flood.
Libo cable was established in 1994,it is subsidiary of Libo group which is one of the 500 largest private enterprises in China.
Libo cable developed the world’s first conforming seamless aluminum tube trunk cable.
Libo cable has a stable workforce and engineering team, the trunk cable is with short lead-time and stable high quality.
Libo cable is equipped with a Provincial-level Research and Development Center.
This is hig quality aluminum tube trunk cable with outstanding bending radius. 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.
