Project Information
Xi’an Triangle Aviation Technology co., Ltd (hereinafter referred to as “Triangle Aviation”) is co-founded by Shaanxi Provincial Government, Xi’an Municipal Government, Xi’an Yanliang National Aviation Hi-tech Industrial base, Shaanxi Hongyuan Aviation Forging co., Ltd and Xi’an Sansen investment co., Ltd.
Triangle Aviation has built a 400MN aviation forging hydraulic press and a forging product line. The total investment of this project is 784 million yuan, and come into use at the latter half of 2012. This project is National “Eleventh Five-Year Technology Support Program”, as well as Shaanxi Key Construction Project of National Aviation Hi-tech Industrial Base. We, Shaanxi XDHI-T Medium and low Voltage Apparatus co., Ltd, support them with 10KV HV control cabinet (S1 electric chamber), DC panel (S11, S12 electric chamber), and DC panel (S1 electric chamber).
Customers' Requirements
10KV HV control cabinet (S1 electric chamber), DC panel (S11, S12 electric chamber), and DC panel (S1 electric chamber). Customers has technical requirements about the 10KV metal-enclosed switchgear on functional design, structure, installation and experiment, thus all our product have meet the National Standard, Industrial Standard, environmental requirement and electric requirement.
