Key Benefits of Medium Voltage Power Cables

When properly specified and installed, medium-voltage power cables offer a variety of unique advantages:

Reliable power transmission. Stable energy flow over medium distances ensures consistent power transmission even in high-demand environments.
Reduced energy losses. The high-quality insulation of MV power cables minimizes energy lost as heat to boost efficiency.
Durability and longevity. Many MV cables are constructed with premium materials to withstand harsh conditions, including outdoor and industrial environments.
Compact. These cables provide more power within a smaller footprint, making them ideal for space-constrained applications.
Safety. Engineered with protective outer layers, medium-voltage power cables reduce the risk of electrical hazards, such as short circuits, faults, and arcing.
Versatility. They are suitable for various environments, including underground, aerial, and open tray applications.

Medium Voltage Cable Construction

A typical medium-voltage power cable consists of the following key components:

Current-carrying conductor. Typically made of aluminum or copper, the current-carrying conductor supports efficient power transmission, low resistance, and minimal voltage drop.
Insulation layer. Insulation provides electrical resistance and enhances safety by preventing unwanted current flow between conductors.
Protective sheath. MV cables also come with one or more sheaths that protect the wires from tension, mechanical damage, moisture, and other environmental stressors.
Shielding. Usually made of copper wire or tape, shielding reduces electromagnetic interference (EMI) and protects against electrical faults.
Jacketing materials. Made of neoprene, XLPE, or other durable material, the outer jacket prevents damage from UV exposure, abrasion, and harsh chemicals.
