SJT is a junior hard-service cord with thermoplastic or rubber-insulated conductors and an overall thermoplastic jacket, rated 300 volts at 60 to 105 degrees C.
SJT, described in hard-service terms, is a junior hard-service cord built with thermoplastic or rubber-insulated conductors under an overall thermoplastic jacket, rated at 300 volts and for temperatures from about 60 to 105 degrees C depending on the construction. The thermoplastic jacket gives the cord durability and resistance to moisture and chemicals, while the junior service rating reflects its duty level.
As a hard-service cord, SJT withstands the flexing and handling of portable use, supplying power to tools, equipment, and appliances. The temperature range indicates the conditions the cord can operate within, broadening its application where moderate heat is present.
In commercial and industrial settings, thermoplastic junior hard-service cords like SJT supply portable power where durability and a range of temperatures are needed. Recognizing the designation is part of identifying cord suited to the application.
Because the temperature range indicates the conditions the cord can operate within, SJT broadens its application where moderate heat is present, supplying portable power to tools, equipment, and appliances with the durability and moisture resistance of its thermoplastic construction.
At Windy City Wire, the focus on quality low-voltage cable and cord includes thermoplastic portable cord types like SJT. Supplying cord with appropriate construction, ratings, and temperature range helps customers match products to portable power needs in commercial and industrial settings.
