Other major substances it resists are gas, ozone, and more.

Due to their great chemical resistance, they are more dependable for industrial applications.

High-Temperature Silicone Cable Buying Guide

No matter what the application of the cables is, the temperature is an important consideration.

There are many applications where the environment may have temperatures of hundreds of degrees.

So the cables should ideally be heat-resistant, and that’s where silicone cables come in.

To maintain the integrity of the circuit, the materials of the cables should be able to withstand high temperatures, especially the outer layers and insulation that may be in direct contact with the environmental conditions.

There are many different kinds of high-temperature cables in the market, with silicone cables being the most popular option.

It’s extremely important that you invest in high-quality cables, especially when dealing with high heat.

What are Silicone Cables?

Silicone cables use silicone, which has a molecular structure resistant to very high temperatures.

It’s also very flexible, which makes these cables easily bendable.

Their reticulated molecular structure keeps them intact, and therefore, the supply runs constantly.

Due to silicone’s high heat resistance, it doesn’t get brittle or inflexible.

High-temperature silicone cables are not just heat-resistant but also resistant to acids, oils, oxidants, and other such corrosive elements.

This makes them incredibly useful in applications where such elements may accidentally come in contact with the wiring.


The construction of high-temperature silicone cables isn’t very different from the typical electrical cables.

These are the main parts of the cable (there may be more layers in some types):


The conductor is usually tinned copper, often stranded.

The class of the copper may vary by each cable standard/type.

That comes down to the application you’re using them for ultimately.

The round strand silicone cables are mostly used in the rail industry.


The insulation is the key element in these cables as it’s made of silicone rubber.

The insulation’s job is to protect and separate the conductor, which silicone does very well, even under high-temperature conditions.

In a multicore cable, each core has its own silicone insulation.

The level of insulation varies and ultimately decides the quality of the wire.

A high-quality silicone cable would have sufficient insulation to thoroughly protect the conductor from outside elements.

Rubber silicone is also resistant to pollutants, which is why these cables are also very long-lasting.

It also maintains its hydrophobicity even after washing.


The outer sheath of the cables is also silicone, as this is the part that is dealing with the heat and other environmental factors directly. Since the sheath is also silicone, these cables are highly flexible.

The color of the sheath is typically red in silicone cables, which has come to become a standard in many industries.

However, the color can vary, and some companies even allow customers to choose the colors, so they can design their own cable color coding.

Heat Resistance

Heat resistance is perhaps the most important characteristic/feature of silicone cables.

In many applications, that’s perhaps the main reason why they are used in the first place.

Silicone cables can operate in temperatures up to 250 degrees Celsius.

Although, most commonly, these cables have a range of -60 degrees to 180 degrees.

When talking about heat resistance, it’s important to make the distinction between heat resistance and fire or flame resistance.

While silicone cables are able to withstand three-digit temperatures, they may not necessarily be fireproof.

That said, it may be fire-resistant or fire-retardant if it has other elements for protection from fire.

Moreover, fire-resistant cables may have even higher temperature resistance, over 600 degrees.

This is because these cables may directly come in contact with flames.

It comes down to the application essentially, whether it requires simply heat resistant cables or fire-resistant cables.

The latter is used in power supply circuits and emergency equipment where the circuit integrity must be maintained at least for a few hours until the fire can be controlled.

Silicone rubber is very popular in fire-resistant cables because of its high heat resistance.


Cables of any kind also vary by their characteristics, which helps you choose the right option for the application in question.

Silicone cables come in all sizes and shapes to meet the varying demands of systems and industries that use them.

Here are the common characteristics:

Voltage Range

The voltage range of silicone cables is 1.1 kV, 3.3-4.2 kV, 6.6-7.2 kV, and 13.8-15.0 kV.

As you can see, there are both smaller and bigger options, depending on where you want to use them.

Bending Radius

The bending radius of a cable basically tells how flexible it is, and silicone cables are inherently highly flexible.

Nevertheless, their bending radius may vary, so this is an important consideration, especially if you’ll need to bend them a lot.

The bending radius is expressed as the diameter of the cable.

In silicone cables, it can be up to 15 times that of the diameter of the cables, which is a pretty low bending angle.

Single and Multicore

Silicone cables also come in single and multicore settings, much like any other kind of cable.

Again, it depends on the application as to which type is more suitable.

Multicore cables are mostly used for high voltage, industrial use.

Standards and Certifications

One of the most important factors when choosing any kind of cable is the standard.

International bodies exist throughout the world that have standardized cable types and constructions to ensure the safety and integrity of the infrastructure they are used in.

Standards also make it easy for the end consumer to find exactly the type of cable they need, as standards also specify the purpose of the cable.

High-temperature silicone cables have their own unique standards.

You can find their standards in the framework of most international and regional bodies.

Here are the common standards for silicone cables:

  • British Standard Institution (BS)
  • International Technochemial Commission (ICE)
  • European Norm (EN)
  • Deutsche Institut for Normung (DIS)

Other than standards, cables should also meet regulatory compliances.

Many countries and regions have laws and regulations in place to ensure the safety and health of people.

Cables certified meeting those safety compliance standards are safer and reliable.

For silicone cables, you’ll commonly see CE and ROHS compliance regulatory compliance certification, which is a European standard but is used globally.

Some examples of commonly used silicone cables and their standards:

IEC Standards: IEC 60245-3, IEC 660332-1-2, IEC

BS Standards: BS EN 50525-2-41, BS EN 60332-1-2, BS EN 60811-1-1, BS EN 5099, BS EN 60228


There are many different kinds of applications for heat-resistant silicone cables.

Some of the common industries that use such cables include:

  • Steel and metal industries
  • Foundries
  • Coke oven plants
  • Medical industry
  • Food industry
  • Hot-rolling mills
  • Ceramic industry
  • Electronic motor engineering

In addition to industrial use, silicone cables are also found in consumer products and domestic use.

These applications may include:

  • Electrical equipment
  • Heating appliances
  • Saunas
  • Oil burners
  • Bakeries
  • Coolers and air conditioners

If you notice, these cables are also popular for applications that don’t necessarily involve high temperatures, rather they have very low temperatures.

This is because silicone’s temperature resistance works both ways.

While it can withstand heat, it can also stay flexible in low temperatures, as low as -60 degrees.

In such cases, it doesn’t get hard or lose its structural integrity.


The benefits of silicone are beyond its heat resistance, but that’s obviously its main attraction.

  • High-heat Resistance: Silicone is an extremely heat-resistant material that can stay intact and not melt even in temperatures upwards of 100 degrees. This is why it’s popular for industries that typically operate in very high temperatures.
  • Low-temperature Operation: Similar to high temperatures, silicone can also withstand frigid conditions. This pairs well with its bendability as it doesn’t get loose its flexibility in cold climatic conditions.
  • Halogen-Free: Silicone cables are normally halogen-free, which is important for safety reasons. In case of a fire, the cable doesn’t emit any harmful gases.
  • Mechanical Pressure: Not all silicone cables are designed for bearing high mechanical pressures, but silicone rubber insulation and sheath, in general, is good under pressure. It can easily withstand a lot of weight and also resist abrasion.
  • Flexible: Silicone cables can also be used in applications where they need to be flexible and bendable. Silicone is an elastic material, and the conductor in these cables is typically stranded– this type of construction results in a higher bending radius.


High-heat silicone cables have many advantages for both high and low-temperature applications.

Not just temperatures, they are also resistant to acids, oxidants, and other harmful pollutants.

These cables ensure the safety of the system and prove cost-effective by preventing damage.

Always makes sure to buy certified cables that follow the set standards.

You should first figure out the application-specific needs and then choose the standard/cable type.

If you’re using it in a setting that’s susceptible to fires, make sure to choose a fire-resistant cable, not just heat-resistant.
