Medium Voltage Power Cables

1. SuperTuffShielded Aluminum Power Cable with TRXLPE Insulation

Medium voltage power cables otherwise known as MV cables can be defined as those cables that transmit voltages of 1 kV to 100 kV. The debate concerning the beginning and the end of medium voltage power cables is still under great controversy as there are various bodies dealing with standard setting with regards to each country. Another factor that dictates the beginning and end of voltage is the kind of system that has been historically used by engineers regarding low and high voltage. The idea to have a medium voltage level was brought into the picture because the degree of voltages kept on increasing and thus the need to have a classification for the levels of voltages.

According to Eland Cables, a top supplier of MV cables, MV cables fall between 3.3kV and 45kV.

MV Cable Sizes
We have MV cables in various cross-sectional size categories as is depicted below. In case you require larger sizes feel free to contact our team and your request will be granted.

Cable	Size
11kV single core	50 mm² to 1000 mm²
11kV 3-Core	35 mm² to 400 mm²
19kV single core	70 mm² to 1000 mm²
10kV single core	35 mm² to 500 mm²
10kV 3-core	35 mm² to 240 mm²
20kV single core	50 mm² to 500 mm²
30kV single core	50 mm²to 500 mm²

As Eland Cables, we have our own standard MV cable portfolio with cables that have single and 3-core copper or aluminum conductors, for the purposes of mechanical protection our cables have steel or aluminum wire amour. Depending where they are going to be used and the kind of task that will be under taken, you can find our cables in various materials such as Ethylene Propylene Rubber (EPR), Polyvinyl Chloride (PVC), Cross- linked Polyethylene (XLPE) and Polyethylene (PE).

If you also need MV standard cables for particular power network requirements we can have them delivered to you in triplex formation. We install our medium voltage cables in a number of industries such as the construction and power transmission industries. Utility companies use our cables to connect residential buildings and industrial buildings. They are also used to connect renewable energy sources to the main grid. Our MV cables are hugely used to distribute power between high voltage main power supply applications and low voltage supply applications.

In order to reduce the number of joints and to make installation easy, we make our cables in various lengths.

Custom Designed Medium Voltage Cables
Because customers are different and come with different needs, we provide custom designed solutions for our medium voltage cables. They are not only developed but also manufactured around various matters such as;

1.Number of cores
2.Stranded copper conductors
3.Solid or stranded aluminum conductors
4.Cross-sectional area

We carry out routine tests on our cables which are not destructive in any way. The tests include;

1.Voltage tests on sheath
2.D.C voltage tests on over sheath
3.Conductor resistivity
4.Spark tests on over sheath

During production we also carry out the following test which are normally potentially destructive;

1.Four hour voltage test
2.Hot set test for XLPE insulation
3.Insulation and over sheath thickness
4.Examination of conductor and dimensions

We carry out type tests in addition to the previous test. These kinds of tests are destructive and are often carried out at the beginning of a cable supply to ascertain its design;

1.on-electrical type tests. These include bending and heat cycle.
2.Electrical type tests. These include testing under fire and mechanical properties.

International Medium Voltage Cable Accessories
To ascertain the optimal performance of our MV cables we do supply a wide range of medium voltage cables such as lugs, terminations, connectors as well as jointing kits.
