Temperature-resistant cables - Reliable connection solutions for extreme temperature
In many industrial applications, cables and wires are exposed to extreme heat and cold. This can cause damage and malfunctions, leading to potentially costly machine downtime. For these types of applications, there are cables and wires available that are specially designed and constructed to withstand temperature fluctuations and are therefore more reliable.
Temperature-resistant cables are a critical component in ensuring safety and performance in industries that require high heat resistance, such as the steel industry. In these industrial environments, temperatures frequently exceed the safety limits of standard cables, posing a risk of electrical shorts or cable breaks due to the insulation burning or failing. Thanks to specialized materials such as silicone, mica, or Teflon, temperature-resistant cables offer resistance to oxidation and abrasion and do not degrade in high-temperature environments.
At HELU, whether it’s control cables, data cables, we offer temperature-resistant cable products suitable for this specific industrial environment. And for cable systems running from substations to factory premises, we also have suitable underground and medium-voltage cables in our diverse product portfolio.
