What is Medium Voltage Power Cable?

Medium voltage power cables are used for electrical distribution. They typically handle voltages ranging from 1 kV to 35 kV. These cables are essential in industrial settings, as they connect substations to transformers. Medium voltage power cables are constructed to withstand higher stresses and environmental factors.

Key Features of Medium Voltage Power Cables

1. Voltage Rating: Medium voltage cables are engineered to carry higher voltage levels. This makes them suitable for commercial and industrial purposes.
2. Construction: These cables are often made from materials like XLPE (Cross-Linked Polyethylene) or PVC (Polyvinyl Chloride). This enhances insulation and durability.
3. Applications: Commonly, you will find medium voltage cables in energy generation plants, large commercial buildings, and utility grade power distribution.

What is Low Voltage Power Cable?

Low voltage power cables cater to electrical systems operating below 1 kV. They are widely used in residential, commercial, and light industrial applications. Low voltage cables are designed for distribution within a structure or facility.

Key Features of Low Voltage Power Cables

1. Voltage Rating: Designed to handle lower voltage levels, these cables are versatile for various applications.
2. Construction: Low voltage cables are usually made from materials such as PVC or PE (Polyethylene). This combination provides adequate insulation for residential and commercial use.
3. Applications: These cables are commonly seen in home wiring, outdoor lighting, and small equipment power sources.

Key Differences Between Medium Voltage and Low Voltage Power Cables

Voltage Handling
