FAQ
MV Cable definition: A medium voltage (MV) cable is a commonly used and highly adaptable form of electrical cabling. It is used within commercial, industrial, and electrical utility industries thanks to its durability and flexibility.
They are typically divided into three categories based on voltage capacity. Low voltage (LV) cables are designed to handle 2,000 V or less, medium voltage cables (MV) can accommodate between 2,000 V and 35,000 V, and high voltage, or extra-high voltage cables (HV or EHV) are rated for voltage above 35,000 V.
The most popular voltage ratings of cables used by the DNO’s in the UK are 6.35/11 kV (12 kV), 12.7/22 kV (24 kV) and 19/33 kV (36 kV), although 3.6/6 kV (7.2 kV) cables and now 38/66 kV (72.5 kV) HV cables are sometimes used on special projects connected with renewable energy.
What is the definition of low voltage, medium voltage, high voltage and extra high voltage? Definitions vary somewhat but a general guide to the voltage categories are as follows: Low Voltage (LV): up to 1000V. Medium Voltage (MV): between 1000 V and 45 kV. High Voltage (HV): between 45 kV and 230 kV.
Low Voltage (LV): Up to 1,000 V AC (or 1,500 V DC). Common in residential, commercial wiring. Medium Voltage (MV): 1 kV to 35 kV.
Medium voltage generally refers to systems between 1,000V and 35,000V. This level is essential for industrial plants, refineries, hospitals, shopping centers, office complexes, and utility distribution systems.
