Roll the sealed type distribution transformer core is developed in recent years, the new generation of low noise, low loss, and its core transformer no juncture, reduce no-load loss and no-load current no-load current, high ~ 80%, 60% lower in iron wire wound on continuous windings, tight, concentricity well. Noise dropped 10 decibels. Due to the continuous winding, iron makes full use of the manufacturing of sexual orientation, no-load loss reduced by 20% ~ 30%, is a new generation of high-tech energy-saving and environmental protection products. The sealed type distribution transformer USES dont hang core structure, make internal and external tank completely isolated, no storage cabinets, the thermal changes in transformer tank operation by elastic corrugated chips to make compensation for expansion, transformer oil and insulation parts with outside air, water, and the separation of transformer oil and slow the aging in insulation parts. Seal of high fuel oil resistant balata, but not in the circumstance that hang core inspection operation for 20 years, reduce operation maintenance cost, be helpful for the inconvenience. Some maintenance The new type S9 oil-immersed three-phases transformer USES unified design standards, advanced and reasonable structure, insulation resistance short-circuit capacity is strong, its performance achieved the international similar product level, with S7 products, on average, no-load loss dropped by 10.25% no-load current decline 37.7%, load loss and lower average 22.4% appearance, reasonable structure according to users chip and tank can tubular radiator, in recent years is one of the most widely used energy saving products. Developed SC9 series of epoxy resin casting dry-type power transformer and air insulated SG type dry type transformer insulation resistance short-circuit capacity, good performance, high impact resistance level of lightning. Epoxy resin casting dry-type distribution transformer winding high by epoxy resin casting seal, adoption of epoxy resin performance is good, crack, high temperature resistant, high mechanical strength, long service life. Flame retardant, moistureproof, explosion-proof pollution-free. Products, small volume, low noise. The winding in the operation of automatic temperature monitoring and are protected alarm device. In the forced air cooling can make the rated capacity over 40%. Can be widely used in high-rise buildings, station, wharf, subway, airport, power transmission and distribution system is the important place. Combined-type distribution transformer (American box variable) is a new body, transformer switch, fuse, tap-changer and relevant auxiliary equipment in one of the transformer. With all its insulation, seal structure, and adopt double welding wire protection. Transformer core adopts special structure, low consumption, low noise, no heat, lightning case. High-pressure line adopts elbow joint, can operate cable 200A load current, can be done in an emergency operation, load switch with isolation switch features. Combined transformer, compact structure, small volume, cover an area of an area small, less investment, easy to install and can be widely used in airport, high-rise buildings, business center, dweller, streets, can further load center installation. When ordering, please indicate the combined transformer or terminal type ring network. SZ type power transformer on-load changer, in use process for saving transformer on-load changer with reliable quality, reasonable, accord with national economic indicators GB1094-1996 power transformer and GB/T6451-1999 ""three-phase oil-immersed transformer, electric technical parameters and requirements. Core adopts the high quality manufacturing, advanced production technology, Oil and winding road structural design is reasonable, high mechanical strength and resistance short-circuit capacity is strong, beautiful generous. 僅作參考: 回答者：網(wǎng)友
