2*50:2根辅助线芯（如中性线和接地线），每根线芯的截面积为50平方毫米 (Two Auxiliary Conductors, such as Neutral and Ground, each with a Cross-sectional Area of 50 Square Millimeters)

电缆结构详解

导体 (Conductors):

通常由多股铜丝绞合而成，提供良好的导电性和柔韧性 (Typically made from Stranded Copper Wire for Good Electrical Conductivity and Flexibility)

主导体数量为3根，截面积为95平方毫米 (Main Conductors: Three in Number, 95 Square Millimeters Each)

辅助导体为2根，截面积为50平方毫米 (Auxiliary Conductors: Two in Number, 50 Square Millimeters Each)

绝缘层 (Insulation Layer):

采用交联聚乙烯 (XLPE, Cross-linked Polyethylene)，具有优良的电气绝缘性能和耐温性能 (Uses XLPE, which has Excellent Electrical Insulation and Heat Resistance Properties)

绝缘层厚度依据电缆的额定电压和导体截面积确定 (Thickness Determined by Rated Voltage and Conductor Cross-sectional Area)

护套 (Sheath):

采用聚烯烃材料，具有低烟无卤和阻燃特性 (Made from Polyolefin Material with Low-smoke, Halogen-free, and Flame-retardant Properties)

提供额外的物理和化学保护，防止外部环境对电缆的影响 (Offers Additional Physical and Chemical Protection against Environmental Factors)
