Through the "three-phase five-limb" structure, frame structure and the rational design, the core is protected to prevent the core from being affected by externally applied forces and thus to ensure its no-load performance. During core mould designing, computer simulation analysis is carried out for precisely calculating the vibration frequency and scale, thus to avoid cavity resonance produced by core structure during operation. During production, special vibration-reducing and noise-decreasing materials are used. All these measures are for reducing the transformer's noise during operation.
HV winding is manufactured with high quality copper wire, reinforced with glass fiber and being casted with epoxy resin at vacuum state with pressure, having the resin fully impregnated into the coils in the most professional imported equipment. Therefore, product's partial discharge is especially low, for example, transformer of 10kV-level has only a partial discharge less than 5 pC. During the HV winding design, rational structure is adopted to improve the electric distribution. With the lighting impulse wave simulation calculation and analysis being carried out through special auxiliary computer software, product's anti-lightning impulse capacity is greatly improved.
LVwinding (with the rated power equal to or higher than 200kVA) is manufactured with high quality foil conductor, resulting in excellent ampere-turn balance, low transverse magnetic flux leakage and higher anti-short circuit capability. By designing reasonable air conduit in the windings to increase the heat-dispersion surface, transformer's temperature rise is effectively controlled and the overload capacity is greatly improved.
