In recent years, CO₂ laser obstacle removers have gained increasing attention from ski resorts. It works by directing high-energy laser beams onto the ice layer's surface, rapidly raising the temperature to melt the ice, thus enabling remote, contactless operation, greatly reducing the risk of manual ice removal and enabling efficient ice removal. ...

The accident caused by ice covering of overhead transmission line is very harmful considering the current situation of ice covering of transmission line at home and abroad. There are many solutions for prevention, melting and de-icing that have been explored at home and abroad. Through research and discussion, the heat transfer and energy of wire icing were analyzed, and a variety of lasers were used for laser de-icing (ice-removing) experiments, and the de-icing situation of CO2 laser was compared. The method, research direction and prospect of laser de-icing has also proposed. ... [Detail]

Trees, kites, nylon bags, shading plastic nets and tree obstacles are all "natural enemies" of overhead lines, power grid has to carry out more than 200 times of obstacle removal every year, which is very difficult to deal with. At present, by using power grid dedicated laser obstacle remover for obstacle removal, time spent is less firstly. ... [Detail]

Bird's nests are often built on power grid rail towers. Branches, grass stems, wire and so on held by birds easily trigger the short connection of the charged body, resulting in tripping, and even burning the equipment. It will cause the power equipment power failure of catenary machines, causing a great impact on the normal transmission and distribution power grid. In particular, birds peck insulator string damage, and bird feces cause insulator string flashing and other circumstances, which will cause more serious power safety accidents. ... [Detail]
