非晶合金鐵芯具有高飽和磁感強度、低損耗（相當于硅鋼片的1/3 ～ 1/5），低矯頑力、低激磁電流、良好的溫度穩定性等特點，用非晶合金鐵芯制造的變壓器，其空載損耗只有現行S9產品的1/4 ～ 1/5，空載電流較S9系列下降20%，節能十分顯著，特別適用于負載率低的用戶，如農村地區和發展中地區。伊戈爾電氣股份有限公司生產的SH15型非晶合金產品、鐵芯采用單框或三相五柱卷鐵芯，鐵芯夾緊件用薄板成型框架結構，低壓線圈為箔繞式，使其損耗低、抗短路能力強、結構先進合理的總體性能基本達到世界先進水平。 SH15 Series Amorphous Metal Core Distribution Transformer is the best energy-saving distribution transformer in the world at present. It saves energy remarkably that its no-load loss is only 1/4 ～ 1/5 of the present products. It especially applies to the users of low load rate, such as the rural area and the developing region. In order to decrease SH15 series transformers’ losses, to enhance its ability to withstand short circuit, its core is made into single ring core or three-phase five-column core, its core clamp is made as frame structure with laminal sheet metal, its LV winding is foil wound. With the application of these advanced technologies, its macro-property reaches the world top level.
