Product category: Product Center dry type transformer series product description: significantly reduce energy consumption, superior performance, reasonable and beautiful design, adopt three-phase three column technology, reduce the floor area by 5% - 10%, use amorphous strip, and reduce the no-load loss by 70% - 80% compared with silicon steel sheet. Low operating temperature, slow insulation aging, long service life of transformer, flame retardant, explosion-proof, no pollution, high fire rating, high mechanical strength, strong ability to withstand short circuit, safe and reliable operation, quick investment recovery benefit, product details, performance characteristics and safety 1) the product adopts Nomex Paper insulation system, flame retardant, explosion-proof, high fire rating. 2) Professional technology, high mechanical strength, strong ability to withstand short circuit, safe and reliable operation. Reliable 1) class H (heat resistant) temperature 180 ℃. The main insulation material is class C (heat resistant temperature 220 ℃), with strong overload capacity. 2) It has the advantages of small partial discharge, high insulation level and long service life. 3) "Three Prevention" ability is excellent, no cracking phenomenon. Environmental protection: 1) the product will not pollute the environment during transportation, storage and operation; 2) the no-load loss is 70% - 80% lower than that of ordinary dry transformer, with remarkable energy saving effect and short investment recovery period. 3) Low noise and maintenance free. 4) The product can be recycled at the end of its life to realize resource reuse. Core features 1) the core raw materials are all made of Hitachi metallic amorphous materials, and the iron loss is 70% - 80% lower than that of conventional products. 2) The structure of the core is simple and the unique process makes it high mechanical strength, and the characteristics and structure will not be affected by transportation and vibration. 3) Amorphous unique three column structure, with the ability to resist high-order harmonics, can use dynll, Yyn0 wiring. Low voltage coil features: the low voltage coil is wound on the high strength polyesterimide cylinder with imported high-quality copper foil and H-class insulating material. The insulating material Nomex Paper is used between layers. The coil is impregnated into a solid whole by VPI vacuum pressure. The upper and lower ends of the coil are sealed with resin. 1) The coil has high mechanical strength and strong short circuit resistance. 2) The coil has strong thermal shock resistance and the product life is greatly improved. 3) The coil has strong ability of "moisture-proof, dust-proof and salt spray proof". Characteristics of high voltage coil: the high voltage coil adopts multi-layer segmented cylinder structure, longitudinal multi air passage structure, uses Nomex Paper wrapped flat copper wire as conductor, uses Nomex Paper as insulating material between layers, the coil is immersed into a solid whole by VPI vacuum pressure, and the upper and lower ends of the coil are sealed with resin. 1) The multi section and layer winding design of the coil makes the distribution of the initial lightning wave point between the turns of the high voltage coil nearly linear, so as to improve the ability of the coil to withstand the sudden wave. 2) The coil has high mechanical strength and strong short circuit resistance. 3) High heat-resistant insulation material and longitudinal multi-channel design make the coil have strong thermal shock resistance and greatly improve the service life of the product. 4) The coil has strong ability of "moisture-proof, dust-proof and salt spray proof".
