Medium Voltage Cables – MV

Medium-voltage cables (MV) are designed for safe and efficient power distribution in a variety of industrial and commercial applications. These cables typically operate at voltage levels from 1 kV to 35 kV and are used in environments where higher power capacity is required but the full capacity of high-voltage cables is not necessary.

Medium-voltage cables are critical for connecting power sources to substations, equipment, and other parts of a power distribution network. Their robust construction, including insulation and armored layers, ensures reliable performance even in harsh environments.

• Energy Storage Systems: In energy storage applications, MV cables help connect storage devices to the grid, enabling effective energy transfer and supply management.

Construction Materials

• Conductors: Typically made from copper or aluminum, providing excellent electrical conductivity for efficient power transmission.

• Insulation: Cross-linked polyethylene (XLPE), ethylene propylene rubber (EPR), or other materials are used for insulation to provide high dielectric strength and prevent power leakage.

• Armoring: Steel wire or tape is often used to provide mechanical protection against physical damage and external environmental factors.

• Sheath: The outer sheath is designed to protect the cable from moisture, UV radiation, and chemicals, ensuring long-term durability.

Types of Medium-Voltage Cables

• XLPE Insulated Cables: These cables feature cross-linked polyethylene insulation, providing excellent thermal stability and high dielectric strength.

• EPR Insulated Cables: These cables use ethylene propylene rubber for insulation, known for its flexibility, resistance to high temperatures, and ability to handle high-voltage stress.

• Aerial Cables: Designed for overhead installations, these cables have strong insulation and armoring to ensure safe power transmission in aerial applications.

• Underground Cables: Specifically designed for buried installations, these cables are equipped with additional armoring to protect them from external physical damage.

Advantages of Medium-Voltage Cables

• Enhanced Safety: With proper insulation and armoring, medium-voltage cables reduce the risk of electrical accidents and fire hazards, ensuring safety in commercial and industrial environments.

• Versatile Applications: Whether used in renewable energy setups, commercial buildings, or industrial facilities, these cables meet the diverse needs of modern power distribution.
