The  230kV power transmission line serves as the power hub among the 27 units in the  entire SADARA complex. It is a critical point on the critical path. Given its  professional requirements and unique functionality, it always attracts attention  of all parties.

Laying, connecting and testing works for the 230kV cables require a  high level of construction skills and mandate highly skilled workers and high  level testing equipment. Installation of cables with such super high voltage and  super large cross section area is unprecedented for SNEI, both at home and  abroad. Successful execution of the project will fill in the blank for SNEI in  the installation of super high voltage power transmission facilities in the  electrical engineering both at home and abroad, and will pave the way for  exploring further opportunities in electrical construction work at home and  abroad in the future. In order to deliver a successful project, the project  management team has spent tremendous efforts in study and investigation,  finetuning the method statement, and strengthening the in-process management.  All personnel involved in the work have gone out their way to ensure a success.  On August 20, 2013, the cable laying activity was kicked off on time, and by  February 28, 2014, all withstand voltage tests for the cables were completed. By  March 1, 2014, all relevant quality inspection documents have been compiled and  handed over, marking the completion of all works for the 230kV power  transmission line, ready for energizing 30 days ahead of  schedule.

In  order to achieve the goals, a series of special measures were taken by the  project management team to ensure safety, quality and progress. Toilets, rest  shelter and drinking water supply are provided on elevated platforms on the  primary and secondary piperacks to improve working efficiency among the  construction workers, which also effectively prevented heat stroke in summer,  and ensured safety of the construction workers; Cable termination room is  provided at elevated locations to prevent the sand and wind from jeopardizing  quality of the cable terminal; prior to laying, the cable tractor, cable layer,  movable (fixed) pulley are reasonably arranged, and potential risks along the  cable route are strictly identified to ensure quality of the cable  laying.

To  celebrate the excellent construction organization and progress control achieved  for the 230kV power transmission lines, on March 12, 2014, the Owner issued a  medal to the E/I team, which says “Celebrating the successful completion of the  installation & testing for the 230kV cables by the E/I team”, to express  appreciation for the outstanding contribution made by the E/I team, and expected  that the E/I team will continue with the momentum to make bigger achievement in  the subsequent construction activities.
