DURIGNIT IR 2000 insulation
Durignit IR 2000绝缘系统包括高质量
enamel wires and insulating sheeting in conjunction with
solvent-free resin impregnation.
绝缘材料系统可确保这些电动机将
具有高机电和电气稳定,高服务
value and a long service life.
绝缘系统保护绕组在很大程度上
against aggressive gases, vapors, dust, oil and increased air
humidity. It can withstand the usual vibration stressing.
