Conclusion Of Suspension Clamp

The LG value (pre-bias) of the installation position of the tension section for continuous up and down hills must be adjusted suspension clamp with i hook, and the installation must be carried out according to the calculated LG value (pre-bias) to make the insulator string perpendicular to the ground plane and meet the requirements of the "110-500kV Overhead Line Construction and Acceptance Specifications". If the LG value (pre-bias) is not calculated and the adjustment is blindly performed, the insulator string deflection cannot be adjusted. At the same time, attention should be paid to the adjustment method. There are many LG value (pre-bias) calculation formulas, and the process is complicated. In the absence of calculation software, the calculation is calculated item by item in a table format to make the calculation process concise and orderly and reduce errors. Check whether the calculation is correct. If ∑⊿LG=0 or ≈0 is correct; ∑⊿LG≠0 indicates that the calculation is wrong and must be verified.
