The intent of the ultimate tensile strength test is to determine the actual measured breaking strength of the cable. The UTS requirement of OPGW used for Wataynikaneyap Power Transmission Project is 116KN, the actual test result can reach 136KN..

The intent of the is to determine the cable tension and strain at which the optical fibers start to elongate. This information is of concern when the cable is exposed to and conditions.

When the tension is 80% RTS, the additional attenuation of fiber is only 0.033dB. The test result is far lower than the IEC & IEEEE international standard requirements.

The intent of the sheave test is to subject the OPGW cable to a simulated action of being pulled over a number of sheaves during installation. Installation includes stringing and sagging operations. During installation, it is possible the OPGW cable could become excessively deformed. The optical fiber unit(s) could also be
damaged, and the optic fibers adversely affected.
