In response to the BID5 project of Ecuador, DINGLI began pre-assembly test of the towers to be supplied in the end of November. Except for the client’s own drawings, the towers supplied in this batch were designed and completed by DINGLI Ecuador Design Center. In view of the impact of the current epidemic, the client cannot visit to China for on-site inspection, so the inspection group was conducted by DINGLI Company for live inspection online, and the Spanish-speaking professionals of the company gave on-site explanations, which achieved good results.
