Medium Voltage Cables

Medium Voltage Cables

Medium voltage cables, also known as MV cables, are defined as those cables with a nominal voltage ranging from 1 kV to 100 kV, according to the International Electrotechnical Commission (IEC).

However, the classification of medium voltage cables may vary depending on the countries, standardization bodies, and systems used. Initially, engineers only referred to low voltage and high voltage, but as the voltage level increased, the need for a broader classification arose, which now includes very low and very high voltage.

Eurisa is a leading provider of medium voltage cables, offering a wide range of cables with voltages between 3.3 kV and 45 kV. If higher voltages are required, the company’s high voltage cable specifications can be consulted. Eurisa’s MV cables comply with various British and international standards, such as the British standard BS 6622 and BS 7835, as well as several international standards of the IEC, such as IEC 60502-1 and IEC 60502-2. Additionally, the company offers a variety of international construction specifications, such as N2SXY, N2XS2Y, N2XSEY, NA2XSY, and NA2XS2Y.

Below are some of the nominal voltages of the medium voltage cables most supplied by Eurisa:

Medium Voltage Cables conforming to British standard:

BS 6622: 6.35/11 kV and 19/33 kV
BS 7835: 6.35/11 kV and 19/33 kV

European Standard MV Cables:

  • N2XSY: XLPE-insulated copper unipolar with PVC outer sheath, available in 6/10 kV, 12/20 kV, and 18/30 kV
  • N2XS2Y: XLPE-insulated copper unipolar with PE outer sheath, available in 6/10 kV, 12/20 kV, and 18/30 kV
  • NA2XSY: XLPE-insulated aluminum unipolar with PVC outer sheath, available in 6/10 kV, 12/20 kV, and 18/30 kV
  • NA2XS2Y: XLPE-insulated aluminum unipolar with PE outer sheath, available in 6/10 kV, 12/20 kV, and 18/30 kV
  • N2XSEY: XLPE-insulated copper triplex with PVC outer sheath, available in 6/10 kV
  • N2XS(F)2Y: XLPE-insulated copper unipolar with water-blocking powder and PE outer sheath, available in 6/10 kV, 12/20 kV, and 18/30 kV
  • N2XS(FL)2Y: XLPE-insulated copper unipolar with water-blocking powder and aluminum tape.
  • N2XS(FL)2Y: XLPE-insulated copper unipolar with water-blocking powder and aluminum tape, available in 6/10 kV, 12/20 kV, and 18/30 kV

These are just some of the options available at Eurisa. It is important to note that nominal voltages may vary according to the specific requirements of each project. Additionally, medium voltage cables may have different conductor configurations, such as unipolar, triplex, or multipolar, and different types of insulation, such as XLPE (cross-linked polyethylene), EPR (ethylene-propylene), or PILC (paper-insulated lead-covered).

In addition to Eurisa, there are other manufacturers and suppliers that offer medium voltage cables with different features and specifications. When choosing a medium voltage cable, it is important to consider factors such as the specific application, installation environment, applicable standards and regulations, and performance and safety requirements.
