Production lines in automobile and motorcycle manufacturers etc. will use lots of electric welding machine, laser welding machine, high-capacity inductive load (mainly motor) and such non-linear loads and thus, all transformer loads have serious harmonic current and frequency spectrum of the harmonic current is quite wide (2nd ~21st harmonics are all severely polluted). So that, electric equipment and transformers have serious harmonic power loss; transformers have the power factor around 0.6 only and seriously insufficient active output capacity. The power grid system thus has great reactive power loss, quick change, unbalanced three-phase load, characteristic harmonic and decrease in total voltage etc., which directly affect the production efficiency of welding.
Shandong XXX Group (the “Company”) was established on May 18, 1993 and main products include three-wheeled vehicle, light truck, electromobile, tractor, engine, tire and combined harvester etc. In accordance with the theory of same platform in the world, the Company has established various industrial parks for agrimotors, agricultural equipment, chemical fiber tire, thermal power, electromobile and modern agricultural equipment, created the development pattern of four major industries, i.e. agrimotors, agricultural equipment, chemical fiber tire and electromobile, and now has the largest production base of transport machinery in China, the production base of low-speed electromobile and the largest production base of chemical fiber to the north of Yangtze River.
