State Grid Jiaozuo Power Supply Company implementing insulation transformation to improve power supply reliability

"After the insulation transformation of this line, the safety operational level and power supply reliability of the line will be greatly improved, and the production and living electricity needs of power users along the line will be further met”, said Hao Tengyu, a specialist in the distribution network management department of State Grid Jiaozuo Power Supply Company, at the insulation transformation construction site of the 10kV Dongjiao left and right lines in Jiaozuo city, Henan province.

It is understood that the line has been in operation for more than 20 years, and because of the bare conductors, there are great safety hazards. On that day, the State Grid Jiaozuo Power Supply Company adopted a group operation method, invested more than 280 construction and management personnel, 29 operation vehicles, and renovated 46 poles and 3.6 kilometers of 10kV overhead lines. After the transformation, the contradiction between trees and lines was effectively resolved, the impact of external force damage on the safe operation of power supply facilities was reduced, and the "happiness" of residents' electricity use was improved.

Since the beginning of this year, the State Grid Jiaozuo Power Supply Company has continued to make efforts to build a strong and reliable power supply network. In the early stage of each project construction, professional personnel has been organized to conduct on-site surveys many times, check the conditions of each baseline, porcelain bottles and other equipment along the line, and tailor construction plans for the transformation of various hidden dangers and defects.

Jointly with the local operation and maintenance units, we visited and investigated the electricity quality of merchants and residents along the line, paid close attention to the frequent power outages and low voltage problems reported by customers, combined with the development requirements of the grid construction, completed the feasibility study of the project in the early stage, and actively promoted the benefits of line transformation to obtain user understanding and support.

In order to ensure that the project is put into production as soon as possible, an operation ledger is made, the construction schedule is reversed, and the implementation plan of the first branch line and then the main line is adopted. Through load transfer, the impact of power outage construction on users is minimized, the number of households during power outages is effectively reduced, and the line transformation is gradually completed. So far this year, 236 distribution network projects have been put into production.

In the next step, the company will continue to work hard to improve the safety and reliability of power supply in the jurisdiction. In addition, continuously attempt to reduce the hidden dangers of natural disasters and external damage, and effectively improve the production and living electricity conditions of customers in the jurisdiction.
