High Temperature Cables

All types of high temperature cables ranging up to -60 to +1400 ° C.

Our high temp cables are designed to withstand harsh and extreme conditions in multiple industrial sectors.

Benefits of High Temperature Cables

High temperature cables play a critical role in many industrial sectors that operate in harsh and extreme environments.  High temperature cables are designed to operate in extreme temperatures, which may go as low as -60°C and as high as +1400°C and ensure the safe and reliable transmission of electrical power and data. They are made from materials with excellent heat resistance and high insulation properties, such as fluoropolymers and silicone. These cables are widely used in various applications, including aerospace, defense, oil and gas, and power generation.

With technological advancements, high-temperature cables have become increasingly reliable and durable, making them a crucial component in various industries. They are essential for ensuring equipment and systems safe and efficient functioning in high-temperature environments.

Improved Performance

High-temperature cables are designed to operate in extreme environments and temperatures, meaning that they are ideal for applications where heat resistance and durability are crucial, such as in furnaces and kiln operations.

Increased flexibility

High-temperature wires are often more flexible than standard cables, making them easier to install and manipulate in tight spaces. Particularly, this is useful in high-temperature applications where movement and vibration occur.

Enhanced Safety

High-temperature cables are designed to be fire-resistant, preventing the spread of fire and reducing the risk of injury or damage. This makes them ideal for use in hazardous environments, such as oil rigs and power plants.

Improved Durability

Improved durability because they are made of materials that resist aging and damage even when exposed to high temperatures over long periods, reducing the need for frequent replacements and maintenance.

Improved Electrical Performance

High-temperature cables have a low electrical resistance, which means they can conduct electrical energy with less heat loss.  This makes them ideal for power transmission and distribution systems, where energy efficiency is crucial.

Silicone Cables

Halogen-free high-temp silicone cable suitable for example as wiring in luminaries, heaters, ovens, griddles, etc., where cables is continuously exposed to high temperatures (temperature range -60 ° C to +180 °C). It is also used as ignition cable in special fixtures.

Fluoropolymer Cables

Halogen-free silicone insulated single conductors for high temperature (temperature range -60 ºC to +250 ºC). We offer this type of cable in a variety of colors and in different designs, both single and double insulated and with various approvals.

Cross-Linked Cables

Cross-linked elastomer-insulated wires and cables offer exceptional properties: temperature resistant up to +150°C, excellent mechanical strength, halogen free, and improved fire / smoke behaviour.

Temperature Rating & Ampacity

It is possible to find both single- and multi-conductor high-temperature cables. Common components of such items include insulation and a conductor (often annealed, tinned, copper-plated, or nickel-coated copper). A fiberglass braid or K-fiber sheath may also be used as an extra jacket for high-temperature wires.

The temperature rating and ampacity of high-temperature cables are two crucial factors in determining whether or not they are appropriate for the intended use.

Temperature Rating

A wire’s temperature rating is the hottest temperature it can be exposed to for an extended period of time without failing. The predicted lifetime of a cable may be shortened if its temperature rating is not appropriate for the surrounding environment.


Ampacity refers to the maximum current that may be carried by an insulated conductor without causing damage to the insulation or jacket. If the cable gets undersized, the circuit load’s heat might potentially surpass the cable’s temperature rating, leading to failure.

Applications with High Temperature Cables

Aerospace & Defense

High-temperature cables are used in the aerospace and defense industry for various applications such as aircraft engines, avionics, and space vehicles. The ability of these cables to function effectively in extreme temperature environments makes them ideal for use in these demanding applications. For example, they can be used to control the temperature of missile systems and the guidance systems of military aircraft.


High-temperature wires are also utilized in the automotive industry for engine management systems, exhaust gas temperature sensing, and electric vehicle charging systems. Their resistance to high temperatures and their durability make them ideal for use in automotive applications, where the cables might be exposed to harsh environments and high levels of mechanical stress.


High-temperature cables are employed in the marine industry for various applications, including ships’ electrical systems to power navigation systems, offshore oil and gas platforms, and underwater remotely operated vehicles (ROVs). Their ability to function in challenging environments, such as high pressure, high-temperature water, makes them ideal for these applications.

Robotics &  Automation

High-temperature wires are implemented in various robotics and automation applications where high-temperature environments are common, such as in foundries and manufacturing plants. For instance, high-temperature cables can be used in the power and control systems of robots used in the foundry industry, where they are exposed to high temperatures due to the molten metal used in casting processes.


High-temperature cables are also used in telecommunications for applications such as data centers and mobile towers. These cables connect equipment and provide power to critical components in these applications. Their high-temperature resistance and durability make them ideal for use in these demanding environments, where the high density of electronic equipment can generate high temperatures.

Energy & Power

High-temperature wires are utilized in the energy and power industry for power generation, transmission, and distribution applications. These cables are used for critical power components in power plants, including turbines, generators, and transformers. For example, high-temperature cables can connect wind turbines in a wind farm, where they must withstand the high temperatures generated by wind-driven generators.
