What is SJOOW Cable?

All About SJOOW Electrical Cable

If you're looking for the right electrical cable for your next construction or electronics project, you may be a bit confused by all the options out there. SJOOW, SOOW, SJO -- with so many different acronyms, it's almost like you're stuck floating in a bowl of vegetable soup!


So how can you figure out which electrical cable is the right one for you? That's where comes in -- we want to ensure our customers are the most educated around so they have great success in finding the products they need the first time around.


First up, we'll take a look at SJOOW electrical cable -- what it is, how it works, its uses and applications, and other information it's important to know. And if you still have questions we haven't answered, feel free to contact us at any time.


What is SJOOW Cable?

In its most basic, SJOOW is a type of portable cord, making it a very flexible piece of equipment for a variety of applications.


Much of what SJOOW cable is all about can be learned when you break down what each letter in its name stands for:


S = Service

J = Junior

OO = Insulation that is oil-resistant

W = Moisture and weather resistant


The SJOOW cable is a thermoset cable, which means it features a very heavy-duty rubber jacket around the copper wires inside. This jacket is made of CPE (chlorinated polyethylene elastomer) and is resistant to a lot of things -- water, oil, sun and heat -- which is what helps allow the SJOOW cable to be used for both indoor and outdoor applications. Many times the outer jacket is also colored in a way to be visible, adding another aspect of safety when in use.


Inside the jacket is normally housed Class K copper conductors, which can be two, three or four depending on the cable. These copper conductors are normally made to be resistant to corrosion. Also inside is generally a layer of EPDM (ethylene propylene diene monomer [M-class]) rubber for insulation. This synthetic rubber provides a great deal of protection to the cable's conductors against things like heat and climate changes.


Then the now shielded conductors are also connected with wax-paper fillers. This extra layer helps make it easier if and when the outer jacket needs to be removed for access to the conductors inside.


SJOOW Cable Uses & Applications

Thanks to its literally dual layer of protection from the elements – both through the CPE jacket on the outside and EPDM insulation on the inside – SJOOW cable is pretty much ready for any situation, both inside and out.  


For contractors, SJOOW electrical cable is a great option for supplying power to portable equipment and tools, as well as appliances that need to be moved about, and smaller machinery and motors. However, it can also be used for more powerful applications -- it can handle larger construction tools and equipment used in heavier industrial projects.


Outside of construction, the thermoset jacket on the outside of the SJOOW cable makes it a great candidate for really tough jobs that can also be quite messy, such as mining and oil processing. Plus the jacket is also resistant to chemicals and acids, making it excellent for hazardous applications.


It can be used with push-button remove controls, and both decorative and movable lighting systems. And you can get techy with it as it's a great option for powering things like data centers and IT installations.


And some SJOOW cables are rated water submersible, allowing them to be used in marine projects – like applications where you would need power at a boat dock or submersible pumps – as you don't have to worry about water destroying the cable.


SJOOW Pros & Cons

As we've already mentioned a few times, the first obvious advantage to using an SJOOW cable is its ability to be used both indoors and outdoors, giving it a lot of flexibility in the application department. In fact, it is usually both UL listed and CSA certified for both indoor and outdoor use, and can be used in a wide range of ambient temperatures, from -40ºC to +90ºC.


And many times SJOOW cable will feature additional industry approvals, including OSHA (Occupational Safety and Health Administration), RoHS (Restriction of Hazardous Substances), MSHA (Mine Safety and Health Administration), Federal and Military Specification J-C 580B, and NEC (National Electrical Code) Article 400. Plus some SJOOW cables out there are even rated as a GreenSpec environmentally-preferred product.


Another pro that SJOOW electrical cable offers is its resistance to things that would cause it to age quickly. For example, its outer thermoset jacket keeps it very unyielding to abrasion. And let's face it -- electrical cables are not usually handled with care. They are dragged, pulled and thrown around, so having a cable that can withstand that type of abuse is a good thing.


Other advantages SJOOW cables offer is a large amount of flexibility – even when used in very cold weather – excellent tensile strength, and in some cases can even be flame retardant and/or water immersible.


Although you might already be sold on SJOOW cable thanks to its impressive list of advantages, it's also important to discuss any disadvantages it may have, especially when compared to other electrical cables.


The first one is that being the "J" in SJOOW stands for "Junior," it is a bit limited in its capability. SJOOW cables are only rated to be used in applications of up to 300 volts. This can obviously be con depending on what your project's needs are.


Another disadvantage to SJOOW cables are their size -- again, being it's a "Junior" cable, they are only available in sizes 10 awg to 18 awg. The overall diameter (OW) Of SJOOW cables are usually smaller than those of other electrical cable options. And SJOOW cables can only be found with 2 to 4 conductors, while other cable options -- such as SOOW cords -- comes with 2 to 40 conductors.
