Regarding electrical cables, temperature resistance is a key factor that can make or break their performance. Aerospace, manufacturing, and automotive engineering industries all require cables capable of withstanding high temperatures without compromising integrity. To meet this requirement, 600V high-temperature cables are the answer.

These advanced wires are designed to endure temperatures from 150-500°C and boast specialized materials. Today, we'll cover every detail you need to know about 600V high-temperature cables – from properties and applications to benefits, types, and how to select the correct one for your project.

600V High-Temperature Cable Properties

The 600V high-temperature cables are insulated and jacketed wires designed to resist fire, heat, abrasion, moisture, aging, and chemical resistance. The insulation material can range from polyvinyl chloride (PVC) to MICA-Transparent Silicate Insulation. Meanwhile, the jacket is made of a glass braid or K-Fiber Kevlar Braid for maximum protection against the elements.

For example, the RADIX Sil-A-Blend® 200C/600V cable is designed to withstand extreme conditions, with a 200°C high-temperature rating and 4 AWG conductor. Its insulation and jacket are made of silicon rubber, making it ideal for use in harsh environments.

600V High-Temperature Cables - Applications and Benefits

Due to their extreme temperature resistance, 600V high-temperature cables are suitable for a range demanding of applications, such as:

  • Automotive and military applications such as engine systems and aircraft;
  • Utility power stations, including solar power generation and wind turbines;
  • Aerospace engineering projects;
  • Drilling and production equipment in the oil and gas industry;
  • Manufacturing plants dealing with hazardous materials and environments;
  • Medical devices, furnaces, refineries, power plants, etc.

The DuraFlex 550 is a prime example of 600V high-temperature cables capable of withstanding extreme heat and abuse. The 10 AWG cable comprises MICA glass composite as its insulating system and a glass braided jacket as the outer coating. The 550°C temperature rating means you won’t have to invest heavily in additional thermal protection.

Let's look at the top benefits of 600V high-temperature Cables:

  • Flexible cutting and stripping characteristics to fit into any automotive, medical, or industrial application.
  • High-temperature resistance
  • Excellent electrical conductivity due to consistent and uniform dimensions throughout the entire length
  • Resistance to chemicals and oil spills.

Exploring Different Types of 600V High-Temperature Cables

Our 600V high-temperature cables come in various types, each with unique characteristics and use cases.

Temperature Rating

The temperature rating of a 600V high-temperature cable indicates the maximum safe operating temperature it can handle before any performance degradation occurs. Most cables have ratings from 150-500°C, with higher ratings showing an increased ability to withstand heat.

Jacket Material

The jacket material of a 600V high-temperature cable is the outer layer that protects the conductor within. It also provides insulation, abrasion resistance, and chemical protection. Common materials used for these cables include glass braided, K-Fiber Kevlar Braid, and Silicon Rubber (SR).

This 500 MCM, stranded 600V single conductor cable comes with K-Fiber-Kevlar Braided Jacket and silicon rubber Insulation to ensure long durability.


The American Wire Gauge (AWG) rating of a 600V high-temperature cable reveals the size of its conductor – the lower the AWG number, the larger it is. This is vital for applications that involve large current flows. For example, a 350 MCM 600V cable has an impressive 350 KCMIL conductor.

Conductor Material

The conductor material of a 600V high-temperature cable is the inner element that carries electrical current. Conductor materials typically include nickel-plated copper and tinned copper. The 18 AWG 19-stranded single conductor cable uses nickel-plated copper as its conductor material. 

Choosing the Right 600V High-Temperature Cable for Your Application

When selecting a suitable 600V high-temperature cable for your application, it's essential to consider what features you need. Temperature rating, jacket material, AWG rating, and conductor material are all factors that can affect a cable's performance in different environments.
