Based on several years’ cooperation with Micron, we have become the bid winner in this bidding about Power supply and lighting equipment procurement and installation project.


Project profile

In December,2013, Micron proposed again 20000KVA, and repeated efforts to communicate Power Supply Bureau, the increase in the original 10KV substation site a ring; Power Capacity: 20000KVA; three indoor 10KV distribution transformer SCB10-2000KVA / 10KV 4 sets; K13-866KVA / 0.4KV transformer 12; 400V 208V low-voltage switchgear and low voltage switchgear 52 sets; Our company is responsible for the production and supply, installation, testing and commissioning, instrumentation monitoring system wiring construction, software development and debugging; lighting plant supplier within three , installation, network cabling room and so are my company responsible for construction completion. At present, the project has been completed and put into use.


Details & Quality

The project's design, construction and the production of power distribution equipment selection, we set strict demands on ourselves, so all engineering and equipment has traced the original file, all construction and operating personnel must be certified, and its wholesale deposit insurance. All equipment in strict accordance with state and industry standards, the implementation of ISO9001: 2008 management, through repeated testing and compliance tested before shipment.


Operational Environments
