5 Top Considerations for Choosing Flexible Medium Voltage Cables

As you know, the medium voltage cable business is full of risk if not carefully handled. When working within a 5kV to 35kV medium voltage range, it’s easy to keep your schedule top of mind, but safety has to come first. Do you have a deployment strategy? How does it perform for you?

Many companies talk about how safety is their top priority and promote the extra precautions they are taking to ensure personnel safety, but all too often, we hear of recordable injuries that could have been prevented by taking a few extra steps.

Think about these five considerations when choosing how to deploy your medium voltage power cables:

1. Flexible medium voltage cables are typically required during unplanned or emergent situations

Deployment of these rugged cables can be quite difficult for workers who are reacting to an immediate and unanticipated need. The thousands of pounds of cables and reels are heavy and require a large amount of manual labor and time to deploy. Does this look familiar? This same, yet very common practice results in a large amount of back injuries and workers compensation claims every year. Does your back hurt just thinking about it? We understand.

2. Flexible medium voltage cables must be properly cut in preparation for connections 

When preparing medium voltage power cables for connector installation, appropriate tools should be used to cut and strip the cable back to prepare it for termination. If cuts are not properly made, the result could be a blown out cable that puts both personnel and equipment at risk.

3. MV cables should have highly engineered connections

The precise layers of semi-conductive material, insulation, metallic shielding, and jacketing materials all help ensure proper installation and crew safety. In order to install a medium voltage termination, technicians should be trained in how to measure all cutbacks and install terminations properly so that the connection will handle the voltage stresses to give your assemblies a longer life.

4. You don’t have time to wait for supplies when an unplanned outage requires immediate action

Some vendors require high minimum runs. Do you really need 3,000 feet of cable? Probably not, and why should you have to worry about storing extra cable or paying for cable you will never use? You should select a vendor who has proper stock available who can cut cables to length and provide you exactly the amount you need when you need it.

5. Consider your deployment strategy and partner

Think about how you plan on transporting these medium voltage cables when they are needed. You might have a "all hands on deck" approach that requires your crew to roll these heavy reels to get them from point A to point B. What if we told you there's a better way?

TPC Wire & Cable Corp. specializes in working with you to properly design a flexible, customizable mobile storage and deployment system that meets your site-specific needs. The final result is a system that allows you to store your cables safely and easily when they aren’t being used, and be able to deploy them with the same ease in multiple locations. 

Our medium voltage power cable technicians have the experience to help you eliminate the risk of failures in the field. We use properly calibrated, up-to-date equipment to handle, accurately measure, and cut the cables to the exact lengths you require. This type of flexibility allows your crews to remain safe while your company restores electrical service more efficiently and faster when unplanned outages occur.

You wouldn’t settle for a bike with no wheels, would you? Of course not. Then, why purchase heavy electrical cables with no storage and deployment strategy? We do sell our heavy-duty flexible medium voltage mobile substation cables without a full deployment strategy, but we consistently ask, “how are you going to get all this cable from point A to point B?” In some cases, our customers aren’t exactly sure.

If you’re in a hurry to deliver your commercial and residential customers with service they can rely on, we have on-site inventory to help you get power restored quickly and strategically. All medium voltage cable assemblies are subject to our electrical hipot testing conducted to current industry standards as another level of protection and security that the product you receive has been properly built and will provide excellent service.

Everything To Know About Medium-Voltage MV 105 Power Cables

A MV-105 Power Cable is one of the most popular power cables on the wire and cable market both in the United States and worldwide. This blog is a tell-all about MV-105 Power Cable, from its applications to variations and unique characteristics.

What Is A MV-105 Power Cable And Where Is It Used?

A medium-voltage power MV-105 cable is a cable with a voltage between 2,4kV and 35kV that is used within the power grid to supply and transport electrical energy.

Despite the fact that medium-voltage cables are a part of the power grid, they do not actually transport the electric level from state to state across the country. This is the job of high-voltage cables on high-voltage power lines.

Medium-voltage cables like MV-105 are used on the preliminary stage between the national high-voltage network and the residential, commercial, and industrial buildings which are the end receivers of electricity.

Medium-voltage cables can be a part of state medium-voltage lines, but they are also very often owned by private companies. Large office premises, production, hospital and campuses, public premises, and radio towers possess their own medium-voltage lines.

What is the difference between MV-95 and MV-105 Cables?

MV-95 and MV-105 are essentially the same type of medium-voltage cable. The difference between them stems from the fact that MV-105 has a maximum conductor temperature of 105 ºC, while MV-95 has a maximum conductor temperature. This impacts the applications of these cables, as they are suitable for environments where the temperatures differ from each other.

The Voltage Of MV-105 Power Cables

MV-105 cables are available in different voltages that fall under the definition of medium voltage, from 2,4kv to 35kv. Some standard variations of medium-voltage cables are 2,4kv, 5kv, 8kv, 15kv, and 25kv/35kv. The 15Kv MV 105 power cable is the most popular one.

Insulation Levels of MV-105 Power Cables: 100%, 133%, and 173%.

One concept that is quite unique to medium-voltage power cables is its insulation level. MV-105 cables are available with 100%, 133%, and 173% insulation levels. The insulation level essentially determines how good the insulation is at dealing with mechanical stress.

An insulation level of 100% means a standard level of coping with the mechanical stress on cables.

An insulation level of 133% is primarily for 15Kv cables, the voltage of which varies within the 15kV/1.732 range. This insulation level is great for environments where voltage variation occurs up to 1 hour at a time.

If the instability lasts more than an hour, then an insulation level of 173%, the strongest one available, is required.

What is an MV-105 Cable With A Concentric Neutral, And When Should It Be Used?

When a cable like MV-105 has a concentric neutral, it means that the said neutral will carry the faulty currents during the faulty conditions, ensuring safe operation of the cable within the electric circuit. 

Because of this additional safety measure, MV-105 cables are used during power distribution, bringing electricity from the transmission lines to devices and equipment. While using an MV-105 cable with a concentric neutral in unstable currents is a necessity, one has to mind that this cable is not flexible and a bit more challenging to install.
