变压器配件-套管

   变压器套管是变压器内部的高、低压引线引到油箱外部的出线装置，具有规定的电气强度和足够的机械强度。与套管连接的线圈，其电压等级决定了套管的绝缘结构。套管的使用电流决定了导电部分的截面和接线头的结构。

The transformer bushing is the outlet device that leads the high and low voltage leads inside the transformer to the outside of the oil tank, with specified electrical strength and sufficient mechanical strength. The coil connected with the bushing ,its voltage level determines the insulation structure of the bushing. The using current of the bushing determines the cross section of the conductive part and the structure of the Wiring head.
