Structure Design
Applications:
Commonly used in newly built overhead power lines.
Can meet the requirements of big number of fibers and ultra high voltage(UHV) transmission lines.
Can provide protection against lightning by transmitting large fault short-circuit current.
Main Features:
Stable structure, high reliability.
Able to obtain the second optical fiber excess-length.
Excellent resistance to distortion and side pressure.
Can withstand high mechanical stress, and excellent lighting protection performance.
Applicable Voltage Range:
Power lines with voltage level of 110KV and below.
