Insulation Layer:
Fiberglass              (ambient temperature range 0-300ºC
 PVC                       (ambient temperature range 0-105ºC)
 Telflon                  (ambient temperature range 0-350ºC)
 Silicone rubber   (ambient temperature range 0-180ºC)
Jacket layer materials: fiberglass, PVC, TF, silicone rubber
Galvanized layer: stainless steel, tinned brass

3.Standard: conforms to IEC584 standard.
