After the on-site demonstration of Shaoxing Power Supply Company of Zhejiang Power Company, Zhejiang Electric Power Company was very interested in the company's HLN-TW100 Nighthawk Night Vision Photovoltaic Recording Instrument and invited us to conduct live demonstrations in the surrounding cities of Zhejiang Province. On May 17, 2019, at the invitation of Hangzhou Power Supply Company of Zhejiang Electric Power Company, we conducted a live demonstration at the 200KV Tower near Xianghu Lake in Hangzhou and the No. 072 Tower of Shengxing 43C1 Line. We carried out the tower on the tower about 2 kilometers from the tower under test. Survey, although the Xianghu area in Hangzhou is in the rainy weather around 15 pm that day, the visibility of the naked eye is low, but after opening the fog-passing mode, we can clearly investigate the tower under test in the night vision device.
