Since 2010, we were the bid winner of MG phase I and II projects. Depends on several years cooperation with Micron and our advantages, we become the bid winner in this bidding about Power Supply and Lighting Equipment Procurement and Installation Project of MG Phase III in 2013.
In December,2013, Micron proposed again to add capacity about 20000KVA, and after repeated communication with Power Supply Bureau, adding one 10kV ring main unit station to its original 10KV substation was agreed; Power Capacity: 20000KVA; 4 sets of 10KV distribution transformer SCB10-2000KVA / 10KV, 12 sets of K13-866KVA / 0.4KV transformers, 52 sets of 400V low voltage switchgears and 208V switchgears are needed in the power distribution room of Phase III; Our company is responsible for the production and supply, installation, testing and commissioning, instrumentation monitoring system wiring construction, software development and commissioning, lighting equipment supply , installation, wring of network room and so on. At present, the project has been completed and put into use.
We supplied Blokset switchgears as required. PS: we are authorized to manufacture Blokset switchgears by Schneider Electric (China) Co.,ltd.
Details & Quality
For the design, construction, selection and production of power distribution equipment, we set strict demands on ourselves, we make record about the project and operation of equipment so that original file of all engineering and equipment can be traced, all construction and operating personnel must have certification for work and we buy insurance for them. All equipment are managed in accordance with state and industry standards and ISO9001: 2008. And equipment can be delivered after repeated testing and results meet the requirements.
Operational environment & Standards
Ambient temperature: ≤+40℃, ≥-15℃, daily average temperature: ≤+35℃.
Atmospheric conditions: clean air, relative humidity when the highest temperature is + 40 ℃ should be less than 50%. At lower temperature, higher humidity is allowed, for example at + 20 ℃, humidity can be 90%, but the occurrence of dewing should be considered due to the change of temperature.
Altitude should be less than 2000m.
