Email● 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:
1. Stable structure, high reliability.
2. Able to obtain the second optical fiber excess-length.
3. Excellent resistance to distortion and side pressure.
4. Can withstand high mechanical stress, and excellent lighting protection performance.
