Huaye Group have undertook a key project of Ecuador state gird and meanwhile faced up with three great challenges ,such as strict international standard, limited manufacturing periods and operation in high altitude location, all staffs are all in this over night and days.Our manufacturing took three shifts per day for production schedule and finally completed 15days before the planned date. The expert group from the Ecuador owner have stationed at the factory for 10 days to supervise the manufacturing process and confirmed that all test items met the latest IEC standard. As the goods have been transported to site by shipment, our after-sales experts also came to the project site 3000m altitude within 48 hours and then worked day and night against strong altitude sickness, servicing continuously for 8 days in an environment with a temperature difference of over 20 ℃ between day and night (usually 13 days). Finally , the owner succeed the Energizing transformer job 5 days before the planned time. Through our hard works and supports from the Ecuador owner, the tested No-load losses is better than 5.2% of the contract values,the running noises is less than 3db than standard, and we have gained the great praise of “Made in China Model ” . This project sets a technological benchmark for the South American market and demonstrates the strength of Huaye Manufacturing power.
