The main difference between spt 1 wire and spt 2 wire in their operating temperature range and application scenarios.
The working temperature range of spt 1 cable is -20 ℃ to 60 ℃, the rated voltage is 300V, the conductor is 20-18AWG bare copper stranded wire, the insulation material is PVC, and it has passed UL VW-1 and CSA FT2 flame retardant tests. It is mainly used for household electrical equipment, such as power extension cords, TV cables, etc.
The operating temperature range of spt 1w wire is wider, from -40 ℃ to 60 ℃. Other specifications are similar to spt 1 wire, and it is also a 20-18AWG bare copper stranded wire with PVC insulation material. It has passed UL VW-1 and CSA FT2 flame retardant tests. Due to its wider operating temperature range, spt 1w wire are more suitable for use in low-temperature environments, such as outdoor waterproof power cord .
