On May 30, 2019, at the invitation of Zhejiang Power Company Jinhua Power Supply Co., Ltd., we came to the State Grid Jinhua Power Supply Company to carry out on-site demonstrations. Due to the harsh geography of the State Grid Jinhua Power Supply Company, the location of the tower Relatively remote, the light effect is dim, so a telescope with better light transmittance is needed. Therefore, the State Grid Jinhua Power Supply Company Inspection Branch expressed great interest in the company's STARRIVER large binoculars and conducted a local demonstration in the local area. The leader expressed his satisfaction with the results of the STARRIVER large binoculars.
