Medium voltage power cables are designed for electrical distribution in a range of applications, typically handling voltages between 1 kV and 35 kV. These cables are essential for transmitting electricity from substations to industrial plants, commercial buildings, and other facilities.
Voltage Rating: Medium voltage cables are rated to handle voltages that fall within the medium voltage range, ensuring safety and performance.
Insulation: They typically use materials like cross-linked polyethylene (XLPE) or ethylene propylene rubber (EPR) for insulation, providing good dielectric strength and resistance to moisture.
Shielding: Many medium voltage cables include a shield to prevent electrical interference and protect against external electromagnetic fields.
Durability: These cables are designed to withstand harsh environmental conditions, including moisture, chemicals, and mechanical stresses.
Conductor Types: Copper and aluminum conductors are commonly used, with copper offering better conductivity and aluminum being lighter and more cost-effective.
