High Temperature Electrical Wire Insulation

High Temperature Wires are ideal for applications with high ambient temperatures. There are different high temp wire insulation materials used, depending on the application requirements and possible maximum temperature. In this article, find out about the different high temperature wire insulation types available in our range and what may be the most suitable for your application. 

Treotham Automation has been providing product and component solutions to Australia’s industrial automation industry for over 25 years. We offer a broad range of international product lines, distributed through our Australian based warehouses and can tailor solutions to exact requirements through our fully equipped workshop as required. 

Below we provide an outline of the benefits, features and capabilities of each high temperature cable insulation type. OLFLEX CRANE PUR2

High Temperature Wire Insulation Types

The type of high temperature electrical wire insulation used will determine the maximum temperature the cable will be able to tolerate. This means choosing the right wire with appropriate high temperature electrical insulation is important. In our range, there are two high temperature electrical insulation types:

  1. Silicon 

Silicon high temperature cable insulation is suitable for use in areas with high ambient temperatures up to +180°C. The products in our range with silicon high temperature electrical wire insulation possess insulating properties after combustion due to remaining SIO2 ash on the conductor.

Our silicon high temperature cable insulation products include:

Applications that cables with silicon high temperature electrical insulation are suitable for: 
OLFLEX CRANE 2ST2

  • Control cabinet, generator and transformer manufacturing
  • Appliances and apparatus engineering
  • Electrical motor industry 
  • Sauna, solarium construction
  • Thermal and heating elements
  • Ventilator engineering
  • Air-conditioning technology 
  • Polymer processing
  • Steel, ceramic and iron works
  • Bakery equipment and industrial furnaces
  • Galvinisation technology

Note: Because the mechanical properties of silicon high temperature electrical insulation decrease from +100°C in the absence of air, adequate ventilation is required when using these cables. 

  1. Glass fibre

Glass fibre high temperature wire insulation is suitable for areas with ambient temperatures from -50 °C up to +350°C. Cables with glass fibre high temperature electrical wire insulation are for use in dry conditions. The core insulation of these cables has a glass fibre covering and impregnated glass fibre braids. 

Applications that cables with glass fibre high temperature electrical insulation are suitable for: 

  • Blast furnaces and glassworks 
  • Motor and furnace construction 
  • Chemical and power station construction
  • Lighting, apparatus and instrument industry
