Chapter 3: How does a medium voltage cable work?

A medium voltage power cable works by providing a low resistance path for the current to flow through.

This cable consists of a core of metal wire offering good conductivity such as copper or aluminum. Along with other material layers including insulation armoring for mechanical protection and sheathing.

These additional layers are designed to allow the metal core to continue to conduct electrical current safely in the environment it is installed.

A good conductor is made of a material whose atomic structure has loosely bound electrons in its outer shell.

This movement of electrons is called current flow. Good insulators have tightly bound electrons which make it difficult for this current to flow.

The amount of current which can effectively flow through the mv power cable will be determined by a combination of factors below;

The effect of the resistance to current flow is the heating of the conductor and the surrounding insulation layers.

Over-heating has the potential to cause the failure of the insulation material resulting in current short-circuiting, electric shock or fire.

You should be careful when handling these mv power cables.

Chapter 4: How do you test a medium voltage power cable?

To ensure the standards of our cables are maintained, testing is one of the practices we normally do at SSG. These tests are done to ensure our products can meet the quality required for optimum problem solutions.

Chapter 5: What are some of the types of medium voltage power cable?

Medium Voltage Power cable from SSG is manufactured in different designs in terms of voltage, size, and length of the core.

To avoid any damage, the XLPE insulated medium voltage cables should be carefully laid and installed.

It must be ensured that the cables should not be pulled over the hard or sharp edges.

The cable ends must be watertight sealed. After cutting the length both ends must be sealed immediately. We normally recommend a laying depth of 60cm.

For laying in conduits, especially the influence of thermal insulation of air space between the cable and inner wall of the conduit should be considered.

The inner diameter of the conduit should be at least 1, 5 times the cable diameter.

Chapter 6: How do you select a cable for medium voltage power?

When selecting mv power cable you have to consider the following otherwise it won’t operate well. If you are unable to select or you have doubts about the cable you can call us to direct you.

When you go to buy a cable for your system how sure you are that it’s the right one for your system. At SSG we guide you in selecting and testing for an mv power cable for your system.

To know if the cable is fit for use in your machine, it should satisfy the following requirements;

1. Built for electrical performance- we manufacture medium voltage power cable with flexible high strand count copper conductors. This is to ensure they can flex and bend without deteriorating the signal.

This means that the cable is more thermally stable at connection points. Also, this provides better corrosion and vibration resistance with a 4-8 time increase in conductor surface area.

So if you are going to buy mv power cable from an industry ask for a high-stand tinned copper circuit conductor.

2. Insulated above and beyond minimum code requirements– Medium voltage optimized cables often significantly exceed the specified minimum wall thickness. The increased safety and performance by reducing the amount of electrical charge in the cable.

This, therefore, enables longer cable distance.

When purchasing medium voltage cable from any shop ask for industrial mv power grade XLPE insulated with the proper RHHW-2 thickness

3. Ground and shielding protection from disruption– All mv power cables should have an excess of copper in the grounding terminal. More copper ensures that all electrical noise within the cable is minimized. Cables with the equivalent of three full-size phase conductors in the ground system will be more effective in contacting noise.

When buying mv power cable ask for a 300 percent ground circuit conductor cable design for a smaller drive. You can also ask for a 100 percent cable design for larger drives.

4. Jacketing options– Medium voltage power cables need to resist damage from physical deterioration while remaining flexible. Cables with different options for industrial-grade jacketing offer performance. We give a bonus of being able to tailor a power cable to your specific application. This all depends on the level of flexibility needed. If your cables face sunlight and oil exposure you need to buy PVC jackets.

If you need to protect your medium voltage power cable from weld splatter and require extreme flexibility you need to use TPE jackets.

We also offer halogen-free jackets with low smoke and zero-halogen upon request.

Using the right MV power cable ensures the benefits you expect. From energy savings to improved process control you can rely on our MV power cables. There are several advantages accrued from using MV power cables from SSG Company.

As long as you use the right cable you can realize all these benefits. By looking out for these four traits when selecting and purchasing MV power cable you are assured of high-quality products that will help maximize your system’s full potential.

Chapter 7: What are the properties of medium voltage power cable?

• Low ground resistance and impedance– MV power cable should be in an attempt to maximize the surface area of electrodes of the conductor with the surrounding soil. This helps to lower the earth’s resistance of the cable and also improves the impedance of the grounding system under lighting surge conditions.
• Equipotential bonding– This helps to ensure that hazardous potential differences do not occur between different incoming conductors. This cable property is essential for ensuring conductors such as metallic water services, power systems do not overheat.
• Good corrosion resistance– MV power cable should be corrosion resistant. It should also be compatible with other conductors buried on the ground system. Our cable is made of copper conductor. The amour is made of non-magnetic aluminum. Maintenance and inspection of the cable should be done frequently.
• Electrically and mechanically robust and reliable– Mechanical coupling should be done to join conductors that suffer from corrosion effect when dissimilar metals are used. MV power cable should resist electrical and mechanically robust. At SSG, we provide excellent low impedance, long life MV power cables with excellent corrosion resistance.
• Good electrical conductor– MV power cables should be in a position to conduct electricity. The conductor is made of copper which has good conductivity and it’s durable.
• It should be in a position to withstand high fault currents– The cable is made of aluminum which can regulate the current since it’s a non-magnetic material.
• Long-life– the cable should at least have over 40 years of performance without any complications. Our cables have achieved this property and gained certifications in long-life cable reliance. A long-life cable also saves you the costs involved in the repair, maintenance, etc. It is cost-saving purchasing a long life cable.
