Details

3D.jpg


Fiber Type: G652D; G655C; 657A1; 50/125; 62.5/125; OM3; OM4 As Options

 

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.
