Qingdao Lutai Power Technology Co., Ltd. Qingdao Lutai Power Technology Co., Ltd. is located in the beautiful coastal city of Jiaozhou, Qingdao. The registered capital of the company is 70 million yuan. It has more than 200 employees, including 34 technicians, more than 70 riveters and welders. It has 750 kV production license for transmission line tower, quality certificate for 500 kV steel pipe tower and quality certificate for 220 kV steel pipe pole, And through the quality management system, occupational health and safety system, environmental management system three system certification. The company covers an area of 66700 square meters, including three large steel structure plants (double span), covering an area of 22500 square meters. The company's products involve all kinds of transmission and transformation line towers, steel pipe towers, steel pipe poles, substation frames, and flare towers for oil fields, with an average annual output of more than 50000 tons of tower components. It can provide general contracting or single contracting services for design, production and installation according to customers' needs.Our company's design, production and testing equipment is advanced and perfect. Computer and software aided design have been widely used in the design: NSA finite element design system of Beijing Daoheng steel pipe pole is adopted in the design of steel pipe pole, and the full stress analysis program of steel tower is adopted in the design of iron tower, which ensures the accuracy of internal force analysis and the rationality of structure, and is in line with the design results of the design institute. In the aspect of drawing and lofting, our company has introduced three-dimensional entity lofting software (TMA, LMA), which connects the computer three-dimensional lofting software with the production line, which can make lofting and production synchronous, reduce intermediate links, improve the dimensional accuracy of products, and ensure the smooth installation of iron tower. In production, there are advanced CNC angle steel and plate automatic processing production line, CNC plasma automatic cutting machine, submerged arc automatic welding machine, gas shielded welding machine, various manual welding machines and other cold working equipment, such as crank press (punch), plate shearing machine, automatic gas cutting machine, hydraulic shaping machine, drilling machine, lathe, planer, sawing machine, super 80 drilling machine, etc Large gantry crane, a total of more than 80 sets. There are 600kN universal testing machine, five metal chemical elements automatic analyzer, spectroscope, impact testing machine, low temperature tank, bolt test mold, ultrasonic thickness gauge, metal coating thickness gauge, ultrasonic flaw detector and other advanced testing equipment.Our company insists on specialty and innovation, attaches importance to the development and application of new products, and constantly develops new technologies and new products on the premise of strictly ensuring stable quality. We have successfully developed angle steel tower, narrow base combined steel pipe tower and single column tapered steel pipe pole, creating good social and economic benefits for power service. Over the years, the company has designed, manufactured and installed iron towers and similar steel structures for hundreds of domestic power departments, communication companies and military departments. The product quality and service have been affirmed and praised by users. Our company abides by the contract and keeps promise, and strives for survival by quality.
