It is planned to complete 62 core areas of the capital, and about 80 kilometers of main and secondary highway power overhead lines will be used for the work. In the meantime, the government will cooperate with the government to carry out the rectification work of the back streets.
At present, the first batch of projects in the streets of Maliandao etc. have been gradually put into construction, and the prelude to the 'General Assembly Battle' has been opened. State Grid Beijing Electric Power will deepen the concept of landscape in terms of equipment selection, continue to choose miniaturization, landscape, and stealth. Equipment, further integration of urban landscaping needs.
Demolition of transformers on poles, removal of poles, installation of box transformers, shutters, laying of cables, construction of cables... With the advancement of the overhead lines of the capital’s core area, the overhead lines in the city, such as spider webs, will gradually The citizens’ life will disappear and the city’s cityscape will be more tidy and beautiful. The safety and reliability of the power grid will be further improved, and it will effectively avoid the damage caused by strong winds, heavy rain, and other bad weather, as well as car crashes and foreign objects. Distribution network failure.
By the end of the “Thirteenth Five-Year Plan” period, the rate of power grid cable in the core area of the capital will be increased from the current 90.2% to 94%, and the reliability of power supply will be increased to 99.999%. The annual power failure per household will be less than 5 minutes.
In the core area of the capital, political power protection is the norm. The successful completion of the Party’s nineteen major and other major political power guarantees demonstrated the continuous improvement of the management level of Beijing Power Distribution Network of the State Grid. At present, the regional distribution automation of Beijing Power City in the State Grid It has achieved 100% coverage and built the first integrated one-piece dual-core distribution automation master station system in the province, achieving 'one-key penetration, holographic control, and cloud integration' intensive operation monitoring and operation and maintenance management; Application of intelligent security, meteorological disaster warning systems, overhead supersonic discharge, 10kV cable ultra-low frequency dielectric loss detection, insulation crossarms and other distribution network state detection technologies; solid development of distribution automation systems and power supply service command platform Enhance the distribution network intelligent perception, data fusion, intelligent decision-making ability.
