Product structure characteristics:
Iron core: adopts High quality cold rolled oriented silicon steel sheet, All - diagonal multi - step ladder joint,tied up without hole, clipped the Stainless
steel drawplate with glass tape tightly.
Coil: winded with non - oxygen copper rod squeezed electromagnetic wire wrapped with high quality paper, insulate the terminal by using company
patent parts, multilayer brush stack end ring, to improve transformer short circuit withstand capability. Adopts epoxy plates pressing device and
increases the quantity of press button and stud to improve the mechanical strength of the coil.
Oil tank: corrugated tank, no lifting core structure, the mechanical strength is high and appearance is beautiful. We have open top type,bell type and
semi-bell type,etc. the oil tank has foundation which conforms to national rail distance standard and provide trolley for installation according to any
customer's civil working requirements. The low voltage outlet busbar adopts company patent big current Groove type outlet terminal to avoid leakage.
Safety protection device: according to relevant state and industrial standard, transformer can be equipped with oil conservator, gas relay,pressure
relief valve, thermometer, oil sampling valve and various gas vent and oil filling valves.
