Medium Voltage ABC Cable
Medium voltage typically refers to voltage levels ranging from 1 kV to 36 kV, although the exact range may vary depending on regional standards.
Application
ABC cables are commonly used for distributing power in residential areas, rural regions, and areas where underground cabling is not feasible or cost-effective.
