HH	Excellent	Excellent	Excellent	Excellent	Fair	High Temp. Glass Braid Over Each Conductor, and Binder Impregnated. Overall High Temp Glass Braid Applied and Bindered. Binder Improves Moisture and Abrasion Resistance But is Destroyed Above 204°C (400°F).
XR	Excellent	Good to 316°C (600°F)	Good to 316°C (600°F)	Excellent	Poor	Braid of Vitreous Silica Fibre Applied to Each Bare Wire. Then Over Both. Suitable to 982°C (1800°F) if Not Subjected to Flexure or Abrasion.
XC	Excellent	Good	Good	Excellent	Fair	High Temp. Alumina-Boria-Silica Ceramic Fibre Braided Over Each Conductor Then Over Both. Not Recommended for Platinum Thermocouples or Exposure to Molten Tin and Copper, Hydrofluoric or Phosphoric Acids, or Strong Alkalies.
