EPR Cable – The Ultimate FAQ Guide

EPR cables cover a wide range of cables made of a wide range of polymers.

It’s an umbrella term that often describes the insulation of the cable (although it also serves as sheath in some cables).

Like PVC, EPR can also be made with specific characteristics as the application demands.

EPR Cables

It is vital to understand the materials that go into any cable, especially insulation.

The efficiency of cables comes down to the conductor and insulation essentially.

The sheath has more of a protective role, so it does not impact performance directly.

In high-voltage cables, EPR insulation filled with minerals is used. It’s applications also vary by voltage ratings.

What is EPR Cable?

EPR or Ethylene Propylene Rubber is a copolymer made from, as indicated by its name, ethylene, and propylene.

It’s also called an elastomer.

This material is mainly used in electrical cables for insulation as its dielectric strength is higher than both ethylene and propylene separately.

Its properties are similar to rubber, so it’s one of the most popular synthesized rubbers in cable manufacturing.

However, unlike natural rubber, EPR is quite soft, which adds flexibility to the cable.

It’s one of those materials that can be molded into different kinds of insulation as per the needs of the system they are going into.

What is the Characteristic of EPR Cable?

EPR is such a common insulation material for a few good reasons.

Its characteristics mimic that of natural rubber and deal with the issues that rubber typically has.

This type of insulation is also making strikes in offshore cabling, as offshore installations are seeing increasingly difficult challenges in deployment.

Here are some of the key features of EPR insulation:

Flexibility

EPR cables are typically flexible because of the rubber-like nature of the insulation.

While the exact bending radius depends on the overall construction of the cable, generally speaking, EPR provides enough flexibility for cables to be used in flexible installations.

It’s also flexible in terms of the level of hardness/softness.

It can be made soft as well as hard, so there are both ends of the spectrum available through a single material.

The actual composition of the polyethylene (PE) and polypropylene (PP) determines how soft or hard the insulation is.

Depending on the application, EPR cables can provide an ample flexibility range.

So you’ll find this material as insulation for both fixed and flexible installations.

EPR Cable

Wide Thermal Range

Another important characteristic of EPR cables is that they have a wide thermal range.

Normally, EPR cables have a thermal range of -55 ℃ to 150 ℃.

The max temperature can be as high as 250 ℃.

The operating temperature range may vary by the individual type of cable, especially depending on the outer sheath if it’s of a different material.

But for the EPR insulation and sheath, the temperature range covers both sub-zero and high temperatures.

Mechanical Resistance

The mechanical properties of EPR cables are also quite impressive, which makes them ideal for tough conditions as well.

Here’s a list of mechanical features of EPR cables:

  • Abrasion Resistance: EPR sheathing in cables provides adequate abrasion resistance, which ensures the insulation and conductor are secure. It’s also resistant to compression.
  • Wear and Tear Resistance: EPR cables don’t wear out so easily, which makes them good for high-voltage, high-cost applications. These can also be used outdoors and for burial. These cables are tear-resistant as well, making it hard for even the sharpest of objects to cut through the EPR sheath and insulation.
  • Impact Resistance: For industrial and commercial applications, EPR has ample impact resistance to withstand mechanical stress and weight without compromising the integrity of the conductor.

Chemical Resistance

It’s important to take into account the chemical features of the insulation and sheathing, especially when the cables are for industrial use or outdoors.

EPR cables offer decent protective features in this regard too:

  • Ozone and Weather: EPR cables are safe from deterioration from ozone and general weather elements like wind, rain, or snow. However, the level of weather resistance varies with individual cables. It’s normally the job of sheath material to provide weather resistance, and EPR doesn’t make the cut when it comes to extreme weather resistance.
  • Oil: Like PVC, EPR also is not the best material for oil resistance. The oils that may come in contact with the EPR sheath may react with it and corrode the outer sheath. The same is the case with insulation. That said, some cables that are used in the food and chemical industries may have other elements in their sheathing to prevent oil damage.
  • Acids and Alkalis: EPR has very good resistance to acids and alkalis. It can even resist organic solvents and, of course, water.

What are the Benefits of EPR Cable?

EPR, especially as an insulation material, offers a wide range of benefits that make it ideal for so many different industries.

Again, it depends on the construction of the cables, their design, and what benefits they can offer.

Here’s a rundown of some of the obvious advantages of using EPR cables:

Suitable for High Voltage

EPR cables are often common in high-voltage applications (thousands of kVs) like power supply to cities and suburban areas.

It can protect conductors carrying high voltage power supply.

Plus, the good thing is that unlike rubber, EPR doesn’t require the tinning of the conductor.

Water Treeing

Water treeing is a phenomenon in which water creates a penetration into the insulation like branches of trees.

It slowly spreads through the insulation, eventually reaching the conductor and resulting in permanent failure.

Ethylene, a polymer in EPR, didn’t have good resistance to water treeing itself.

However, with propylene, it does offer good resistance to water treeing.

EPR generally has low sensitivity to water treeing.

It’s ideal for offshore and outdoor cables that may be in constant contact with water.

It will prevent the water from seeping into the insulation.

Reliability

EPR insulated and sheathed cables are highly reliable in many aspects, be it flexibility, heat-resistance, or weather-resistance.

They help maintain the integrity of the conductor even in some tough conditions.

As insulation, EPR is one of the best materials in so many different situations.

When it comes to cables, regardless of the application, reliability is a key consideration for both suppliers and consumers.

Variety

EPR cables offer a variety of properties and use cases, catering to many different industries.

This is what makes these cables truly versatile.

EPR can be customized to provide purpose-specific characteristics that suit particular applications.

Reduced Thermal Expansion

EPR offers reduced thermal expansion, which makes it ideal for use in high temperatures, as high as 150 ℃.

Resistance to Partial Discharge

EPR insulated cables also show resistance to degradation through partial discharge, which makes them all the more reliable for electricity purposes.

What is the Application of EPR Cable?

EPR cables are most common in the electrical industry for the production and distribution of power.

EPR insulation has become almost a standard in the industry on all levels, from production to utility.

EPR Cables

Here are some examples:

  • High-voltage power supply
  • Feeders
  • Distribution

What is the Difference Between EPR Cable & XLPE Cable?

XLPE (cross-linked polyethylene) and EPR are two of the most common insulation materials in cables.

PVC is the third most common, but it’s limited to low-voltage cables only.

In fact, XLPE and EPR have become de facto choices of insulation, especially for electrical cables.

While these are both thermosetting copolymers or elasto polymers, these two materials, and hence the cables they are used in, have differentiating properties.

EPR cables are more flexible than XLPE simply because of their molecular structure.

XLPE is also a flexible material for insulation, but when compared to EPR, it falls short.

So in applications where there’s a need for flexibility and a higher bending radius, EPR would be a better option.

EPR Cable

Both EPR and XLPE as thermosetting plastics offer high temperature ranges.

XLPE can also withstand high temperatures easily.

Its normal operating temperature is 90 ℃ to 110 ℃.

Similar to EPR, its threshold for short circuits is 250 ℃.

One area where XLPE beats EPR is dielectric losses.

EPR has higher losses than XLPE, which makes it more cost-effective than EPR.

Overall, XLPE is a bit more economical than EPR because of fewer losses.

XLPE is somewhat resistant to water treeing but not completely.

In comparison, EPR cables are much more sensitive to water treeing.

That said, some XLPE polymers are specially treated to be water treeing sensitive.

What is the Standard of EPR Cable?

There aren’t standards that specifically classify cables as EPR cables.

Standards typically outline the construction and application of a cable, and that’s where EPR fits in.

Depending on the requirements, EPR may or may not be a part of the cable.

Standardization not only helps ensure quality and safety, but it also makes it easy for the supplier and consumer to know exactly what they want.

Standards for EPR cables technically include all those standards that specify thermosetting materials for insulation.

EPR Cable

For instance, IEC 60502-1 standard for extruded insulation power cables with a voltage rating of 1 kV to 3 kV requires a thermosetting insulated compound, which includes EPR, XLPE, and HEPR.

When looking for standards around the world, here are some of the most common ones:

  • International Electrotechnical Commission (IEC)
  • British Standards Institute (BS)
  • European Standards (EN)
  • Japanese Industrial Standards (JIS)
  • DKE – VDE (Germany)
  • NEK

There are safety certification/rankings as well when it comes to cables.

Insulation and sheathing materials have to pass those safety tests to get those ratings.

For instance, in Europe, the cables have to be CE certified, and sometimes ROHS certified too.

This ensures that the manufacturer has tested and abided by the safety standards set by European authorities.

What are the EPR Cable Types?

Conclusion

EPR material has come a long way in the cable industry.

EPR cables are some of the toughest ones for power supply and distribution.

They have certain advantages over XLPE, which is its main contender when it comes to cable insulation.

It does have dielectric losses, but that’s not non-existent in XLPE either.

The EPR cables are primarily used in the electric industry, but you’ll find this material in insulation in other industries as well, particularly offshore machinery and installations.

When choosing EPR cables, or any other cable for that matter, make sure to check which standards the manufacture has followed for producing the cables and whether those standards are followed in your industry.
