SCB13 energy-saving dry distribution transformer is a new generation of energy-saving and environmentally friendly dry distribution transformer designed and developed by our company through scientific and reasonable electromagnetic calculation and new pouring process on the basis of absorbing foreign advanced technology and advanced experience in the same industry. The product has the characteristics of flame retardancy, fire protection, explosion-proof, small size, maintenance-free, and pollution-free. The product is widely used in urban power grids, high-rise buildings, business centers, theaters, hospitals, hotels, tunnels, subways, underground power stations, laboratories, stations, docks, airports, combined substations and other important places. SCB13 energy-saving dry distribution transformer core adopts a new full oblique, seven-step stepped stacked seam form. Compared with the conventional seam core, it can reduce the magnetic density at the seam by about 22%, reduce the no-load loss by about 3%, reduce the transformer noise by 2-3 decibels, and reduce the no-load current by about 40%. Stacking 7 pieces at a time greatly improves the stacking efficiency. The clip used adopts a fully automatic laser cutting steel plate numerical control bending structure. Bending parts have the advantages of few parts, high processing accuracy, accurate positioning, simple assembly, simple surface treatment and painting process. The core insulation is made of PET (H-class) insulation material to ensure that the transformer does not generate discharge, leakage, breakdown, etc.; the clip is smooth in line, smooth in appearance, beautiful and beautiful in appearance.
