Medium Voltage (MV) Cable
The idea of medium voltage was first developed as voltage levels escalated and the necessity for a wider classification range arose, which now frequently includes extra low and extra high voltage.
Medium Voltage cables, or MV cables, is a category defined by the International Electrotechnical Commission (IEC) as having a voltage rating of above 1kV up to 100kV.
Medium-voltage cables are plastic cables insulated using cross-linked (XLPE) polyethylene, representing first-class insulation technology.
Our standard medium voltage cable portfolio, as a specialist MV cable supplier, includes cable with single and 3-core copper or aluminium conductors, steel or aluminium wire armour for mechanical protection, and various application-specific materials such as Polyvinyl Chloride (PVC), Polyethylene (PE), Cross-linked Polyethylene (XLPE), and Ethylene Propylene Rubber (EPR) Low Smoke Zero Halogen characteristics, as well as oversheathing qualities (LSZH).
We also offer medium voltage standard cables in triplex configuration, which are created to meet specific power network requirements. Our MV cables are used in a variety of industries, including construction and power transmission. They’re frequently utilised for power distribution between high-voltage mains and low-voltage applications, as well as by utility companies to connect residential and industrial complexes to the major grid, as well as renewable energy sources like wind and solar farms.
Our MV cables come in a variety of lengths, including extended long lengths, to make installation easier and reduce the number of joints.
MV Cables Uses:
Medium-voltage cables are utilised in industry, power production, power transfer and distribution, and wind farms because they are exceptionally reliable. Furthermore, these medium-voltage cables are employed in public transportation infrastructure, such as railway and metro lines, to provide power. Our medium-voltage cables can be made of special plastics if needed, and they have a fire rating, allowing them to be installed indoors and in tunnels.
MV Cable structure and materials
The sizes and types of medium voltage cable designs vary. The structure is significantly more complicated than that of a low-voltage cable.
The distinctions between medium and low voltage cables are not only in the manner they are built, but also in the production techniques and raw materials used.
In fact, the insulation methods for medium voltage cables differ significantly from those for low voltage cables:
Instead of one layer, the medium voltage cable has three: conductor screen, insulation material, and insulation screen.
In the case of medium voltage, CCV line is used instead of standard horizontal extrusion machines, as it is in the case of low voltage.
Even if the insulating material has the same name as low voltage cables (for example, XLPE), the source material is different to provide more pure insulation. Colouring masterbatch, which is used for core identification in low voltage cables, is not allowed. The metallic screen, which is usually seen in medium voltage cables, is only employed in low voltage cables for certain applications.
Medium voltage cable goods, like all other cable products, require extensive type testing to analyse the individual components as well as the entire cable. Electrical, mechanical, material, chemical, and fire characteristics of medium voltage cables are all tested.

APPLICATIONS FOR MEDIUM VOLTAGE CABLES
In the event of a natural disaster or unpredictably long power outages, primary power is provided by a mobile substation.
Power supply for substation construction
Distribution of power to remote places
Applications ranging from 5kV to 35kV are available.
Substations are places where electricity is generated.
Transformers are a series of robots that transform
Sets of medium voltage generators
To cut down on downtime, choose a high-quality product that will last and can tolerate harsh situations. Choose a medium voltage electrical cable source that stocks, custom cuts, packages, and connectorizes the product so it’s ready to instal as soon as it comes to keep people safe and save money.
Znergy Cable is close to its clients and understands their requirements. As a result, we don’t limit ourselves to ordinary items; we can also create customised items that demand unique solutions, such as specialised wire structures. Medium-voltage cables are mostly utilised to construct weather-resistant networks and to increase network stability. The usage of medium-voltage cables allows electricity networks to be transferred underground, which has proven to be a dependable technique of minimising storm-related power outages. We can also ensure that society’s working capacity is maintained by creating power networks that are more robust to adverse weather and demanding conditions.
