Installation Process Of Suspension Wire Clamp

The installation ab cable suspension clamp process has a decisive influence on the outlet stress. When the conductor is embedded in abc suspension clamp during tension release, the angle deviation exceeds 5°, which will cause j hook suspension clamp the stress distribution unevenness to increase by 40%. In the construction of a 500kV compact line, a torque wrench is used to control the tightening torque of the U-bolt within the range of 25N·m±10%, and the conductor marking error does not exceed 1‰ of the span, so that the standard deviation of the suspension clamp for ab cable outlet stress is reduced from 18MPa to 9MPa. When the value deviation of the temperature compensation coefficient α is 0.5×10^-6/℃, an additional stress of 7MPa will be generated under a temperature difference of 40℃.
