Dry type resin insulated SC(B)10 distribution transformers

Jiangsu Xiongfeng Electrical Equipment Co., LTD. mainly produces oil-immersed power transformers, amorphous alloy transformers, epoxy resin cast dry transformers, combined substation and so on.   This series of products is filled with short glass wire casting coil adopts segmented cylinder type, the coil is provided with axial airway to improve heat dissipation conditions. The scientific casting molding process can ensure that the resin fully penetrates into the turns, layers and segments to ensure the electrical insulation strength of the product and less office discharge (≤5pc).   How to prevent the cracking of the resin castable body, control the generation of residual bubbles in the castable body, and reduce the discharge to the minimum limit has been a major issue for domestic and foreign dry transformer manufacturers, and is the key manufacturing technology of resin castable dry transformer. Through repeated production practice and frequent physical and chemical test…
