High Temperature Cable : High Temperature Cable Specifications & Guides

Extreme & High Temperature Cables

In2Connect can help solve your toughest wire and cable problems. Providing wires and cables designed to operate in a temperature range from -100°C to +1000°C requires a great deal of experience in selecting the most suitable raw materials and cable constructions for the application.

From blast furnaces to cryogenics, we have many years of such experience in high temperature cable.

Wire and cable insulation's commonly employed include: Kapton Polyimide tape, modified silicone rubbers, magnesium oxide, Teflon®, polyurethane, PTFE, mica tapes, TPE, foamed FEP or Tefzel®, thermo-set cross-linked polyolefin etc.

By careful selection of these materials and utilising worldwide industry standards, we aim to keep minimum manufacturing quantities land lead times low.

From single conductor to complex composite thermocouple cables the product mix includes: fixed and flexible wiring cables, furnace/areo engine test bed instrumentation cables and thermocouples, and fire 'critical' circuit cables.

Our experience in tough wire and high temperature cable applications allows you more choices than ever before and in the end, the right cable for the job.

Conductors ~In the UK plating is generally employed on copper or copper alloy conductors to improve resistance to corrosion/oxidisation at high temperature and to assist termination.

Very often it is the plating which will determine the temperature rating of a given cable and the accepted UK 'norms' are:

Tin plated copper continuous	135ºC
Silver plated copper continuous	200ºC
Nickel plated copper continuous	260ºC
Nickel Clad plated copper continuous	260ºC

For cables operating at a high temperature, e.g. 260ºC to 500ºC, Copper/Nickel, Nickel/Chrome (Nichrome) or other suitable high conductivity alloys, or even Grade A Nickel will need to be utilised. Pure Nickel has around 17% the conductivity of electrolytic copper, hence can generally only be used for signal/thermocouple applications. The more common 27% Ni-clad copper conductors (which will ultimately promote long term conductor life in the presence of long term heat and flexing) have circa 70% ~ so cables required to carry LV power at temperatures above 500 degrees C are generally limited to the sort of MICC construction available from your local Electrical Wholesaler.
