The invention relates to the technical field of transformer bushings, in particular to a transformer high-voltage bushing and a manufacturing method thereof. The transformer high-voltage bushing comprises an inner copper body and an insulating porcelain body arranged outside the inner copper body in a surrounding mode, the insulating porcelain body comprises an insulating inner layer, a capacitorelectrode layer, a filling base material and an outer dressing, and the capacitor electrode layer is made of conductive cloth, a conductive net and conductive yarn; the filling base material is one ormore of adhesives and lubricants, and the external dressing is sodium sulfate. A bushing is prepared from diatomite, feldspar powder, quartz powder, illite powder and other materials, and a capacitorelectrode layer is arranged on the outer side of the bushing, so that the electric breakdown resistance of the bushing is enhanced, and epoxy resin or insulating oil penetrates through the bushing and is integrated with the insulating inner layer. The medium loss of the high-voltage sleeve is reduced, the mechanical strength of the sleeve is high, the outer side of the sleeve is coated with the outer dressing, the outer surface of the sleeve is smooth, a hardness cavity is formed, and the protection capacity is good.
本发明涉及变压器套管技术领域，尤其涉及一种变压器用高压套管及其制作方法，包括内铜体及环绕设置于内铜体外部的绝缘瓷体，上述绝缘瓷体包括绝缘内层、电容电极层、填充基料及外敷料，电容电极层采用导电布、导电网及导电纱，填充基料为粘合剂、润滑剂中的一种或多种，外敷料为硫酸钠，本发明利用硅藻土、长石粉、石英粉及伊利石粉等等材料制备套管，且在其外侧设置了电容电极层，增强了套管的防电击穿性能，使环氧树脂或绝缘油贯穿，与绝缘内层融为一体，使得高压套管的介质损耗降低，套管的机械强度强，且在外侧涂覆有外敷料，套管外表面光滑且硬度腔，防护能力较佳。
