Industrial collaboration:Promote the development of the high - end electrical equipment manufacturing industrial chain in Guangxi, achieving regional technological upgrading and economic stimulation.
2. High Sealing Reliability Applying multi - seal ring technology and process, it significantly improves the air chamber sealing performance and ensures the long - term operational stability.
3. Intelligent monitoring function
Equipped with an electronic density sensor, it reduces intermediate connection links and enables real - time status monitoring and fault early warning.
4. Localized production support
Siwu Electric has achieved localized production of core equipment in Guangxi, shortening the supply chain cycle and improving the service response speed.
1. Severe space restrictions
The space of subway substations is limited. Traditional switchgear has a large volume, making layout difficult.
4. Localized production requirements
The industrial chain of high - end electrical equipment manufacturing in Guangxi region urgently needs to be improved, and the localization of key technologies needs to be promoted.
2. High reliability requirementsThe traction power supply system needs to operate under high load for a long - term, which has extremely high requirements for the sealing, insulation, and stability of equipment.
3. High maintenance complexity Traditional equipment inspection is cumbersome, and the operation and maintenance costs are high. It is necessary to reduce the failure rate and maintenance frequency.
