CNE has established long term cooperation with many famous universities and institutions in China, such as Qinghua university, Xian Jiaotong University, Beijing Technology University, Nanyang Explosion Proof Electric Research Institution etc. Meanwhile, the company has conducted many technical exchanges and introduction from many international famous companies and institutions, such as GE America, Siemens and LDW German, PPI UK as well as International Copper Association etc.
CNE possesses the domestic fist-class manufacturing facilities including heavy-duty digital lathe, large-sized floor-type milling & boring machine, large-sized key slot milling machine, digital winding machine, digital coil spanning machine, digital coil taping machine, digital high-speed punching machine, high pressure die-casting machine, induction brazing machine, VF3 machining center, advanced resin sand molding line and automatic welding equipment etc. All of these advanced facilities provide reliable hardware guarantee for the manufacturing of all products’ key parts.
With the special inspection and test capability of spectral analysis, mechanical properties inspection, ultrasonic wave inspection, magnetic particle inspection, color penetrant inspection and iron loss test etc, the intrinsic quality of the key parts can be controlled effectively. The introduced balancing and rotor over-speed test facilities with technology from Schenck German as well as the domestic first-class vibration spectral analysis can meet the balancing and precision requirement of the motor rotor dynamic balancing. Advanced VPI vacuum pressure impregnation insulation system for motor insulation treatment can meet the high standard requirement of heat resistance, high voltage resistance, anti-shock and anti-corona. With the domestic largest 7500KVA test unit, the test can be carried out comply with IEEE-112B standards in USA and the testing standards are in line with the international test standards.
