In our This vs. That series, we compare two similar products to help you learn more about them. By outlining the differences, comparing the construction, and providing application uses, we want to help you know which product is best for your next application. In this post, we compare the SJT and SVT cables.

Both SVT and SJT are portable cords, meaning they are cables with multiple conductors meant for temporary electrical power connections requiring flexibility. Portable cords such as SJTand SVT cables are both durable and resilient. Since they’re used in many applications, ranging anywhere from lamps to construction equipment, they don’t have any other choice but to be reliable, strong, and long-lasting.

A Closer Look

When discussing portable cords, the name is the most important. Each letter represents a rating applicable to the cord. The relevant letters and their meanings for this article are:

  • “S” = service, meaning the cord has been rated for 600 volts or less.

  • “V” = vacuum cord, which references one of the cable type’s common applications. Rated to 300 volts.

  • “T” = thermoplastic, which refers to the material the cord jacket is made of and is light-duty. Typically used as a consumer-grade portable cord.

  • “J” = junior, short for Junior Service, meaning the cord has been rated at 300 volts.

How Do They Compare?

The fundamental difference between SJT and SVT cable is the thickness of the cable. Since it has thicker insulation, the SJT cord has a larger overall diameter than the SVT cable.

SJT cord is also available in a wider spectrum of gauges, increasing the variety of power needs this cable can meet. Common applications for the SJT cord include portable lights, heavy tools and equipment, power extensions, and use in other hard service functions. SVT cable, on the other hand, is more often used in light-duty applications, including providing power for small tools and appliances, food processors, and office equipment.
