> SD-10-LMZC系列套管式电流互感器,为圆孔型, 主要适用于电缆穿越,作为继电保护使用。该型电流互感器的环形铁芯和二次绕组采用优质环氧树脂浇注在可阻燃的塑料壳体中,防潮湿,性能稳定,免维护。 > 依据穿孔尺寸、电流变比、准确级和额定负载的不同, 该系列互感器分 为以下几种类型,具体参数详见参数表。 > SD-10-LMZC series bushing type CTs are round window style, mainly adapted to cable entry as relay protection. This kind of CT’s ring core and secondary winding use high quality epoxy resin via vacuum pouring to flame retardant plastic housing, avoiding damp, having stable performance and maintenance free. > According to the difference of window dimension, current ratio, accuracy class and rated burden, the series CTs are classified as following types, detailed see the parameter tables of each type.

备注
1、请注明互感器型号、额定电流比、准确级、额定容量及安装方式等;
2、电流互感器的主绝缘由一次电缆保证,产品仅考核二次对一次及对地的工频耐压(3kV);
3、如有特殊要求,可与我公司联系,以便按需定制。
1. Please specify the model,rated ratio, accuracy class,rated capacity,and required installation method,when placing a purchase order.
2. The mail insulation of the CT is secured by the primary cables, only to check the power frequency withstand voltage between secondary and primary(3kV).
3. If any special requirements,please contact us,so we can custom make upon request.
