Primary Wire - T6 (200°C)

Turning up the heat. TE's class F, T6 primary wire can withstand temperatures up to 200°C and provides a thin-wall/ultra-thin-wall engine harness wire used with high-performance fluoropolymer insulation systems in applications where space and weight reduction are needed.

Space and weight savings in extreme temperatures.  

Our robust and advanced Raychem radiation cross-linked fluoropolymer insulation offers exceptional high-temperature performance and resistance to hot surface damage.

The durable mechanical characteristics also allow TE to produce these wires in a thin-wall version, for space and weight saving and the opportunity to remove over-protection.

Core Technologies

Technical Leadership in the Wire and Cable Industry

  • TE's Raychem is a pioneer of radiation cross-linking, and one of the leading supplier of such products worldwide.
  • All of TE's major product lines use insulation formulations developed in-house, and tailored to give optimum performance for each specific need.
  • When TE develops any new product, we test it well beyond the limits of international and OEM specifications, to ensure that it will not only exceed expectations in service, but will be as easy to process and install as possible.
  • TE employs state-of-the-art manufacturing techniques to ensure that consistent product quality is achieved. 
  • TE provides comprehensive handling guidelines with our products, and our expert technical support team is always on hand to respond to any technical queries that may arise.


  • Continuous operating temperature from -40°C to +200°C (3000hrs)
  • Resistance to hot surface damage
  • Outstanding resistance to vehicle fluids
  • Superior cold-flow and cut-through performance compared to PTFE or FEP
