SJTW Cable: What does it mean and how is it used?

SJTW means hard service cable – built thermoplastic jacket – 300 volts – weather-resistant for outdoors. Service is S, J is Junior, T is Vinyl thermoplastic, W-A means Approved weather.

Power cables are the fundamental components of any type of electrical system. There are various types of cables available on the market. The choice of which particular types of cables can be used for specific purposes is dependent on a variety of factors, the most important of which is the technical requirements of the functions.

As much as you can be not so new with electrical cables, there may be things about power cables that are new to you, just like the SJTW cable. If you’re trying to learn more about the SJTW cable, you might find it fascinating that the cable has a number of different applications. Much of the time, cables are commonly used in lighting and electrical equipment industries. There are also several different types of SJT cables, each with its own advantages and drawbacks. Most of the companies that use this cable have a strong knowledge of the different types of SJT cable applications.

SJTW Cable: What does it mean and how is it used?

SJTW is an industry-standard abbreviation used on wire and cable. S is for service; J for junior (defined as hard service instead of extra hard); T is the coating (thermoplastic/vinyl); W is weather approved. It means it is a hard service, thermoplastic cable rated for 300V and approved for outdoor use.

Applications of SJTW Cable

Industrial Uses

In assessment on what kind of applications SJT cables could have, it may be useful to look at their size and number of conductors. In particular, the bigger the cable size, the more capable it is of supporting large levels of power. Therefore, if you discover that there are a lot of large cables to be used for business purposes, it is likely that they are looking to use SJT cables for industrial purposes. But from the other contrary, cables that you would find in small companies, such as professional digital studios, will use much smaller cables as they do not require the level of power support that is needed for industrial enterprises.

Lighting

Whenever it comes to lighting, the SJTW cable is one of the easiest rubber cables to use. It is because the different properties found inside the cable make it the ideal choice for lighting contractors and professionals. This implies that lighting for industrial settings or for other situations, such as professional photoshoot illumination, can be assisted by this form of cable. As you might expect, the type of cable used for professional photo sessions is very different from that used for industrial lighting. They are both SJT cables, however, and thus demonstrate the flexibility of the cable.

Electrical Appliances

In addition, several companies requiring the use of electrical equipment would power these appliances via SJT cables. This is because the SJTW wire is very durable and can support very high levels of electricity. As a result, this type of cable is in heavy use for industrial scenarios and smaller commercial scenarios. The use of SJT cables when it comes to various electrical equipment typically means using different lengths and sizes to ensure that the most reliable power supply of these appliances is achieved.

SJTOW vs SJOOW

There is another variant for SJTW cable where they add the letter “O”, meaning oil resistant. If you can observe, there’s a lot of variation between SJTOW cable and SJOOW cable. Each of these portable cords are weatherproof junior service cords that are classified at 300V and also have similar applications. Well, what’s the difference, then? The greatest difference between SJTOW and SJOOW lies in the makeup of the cable.

The “T” in SJTOW means thermoplastic materials in the jacket as well as insulation. This unique thermoplastic material used in our SJTOW is made of PVC. One “O” means that only the jacket is oil resistant, not just the jacket and the insulation. As it comes to SJOOW, the lack of the “T” means the rubber is used instead of thermoplastic. Double “OO” means that the jacket and the lining are resistant to gasoline. In this situation, the rubber compounds used in our SJOOW cables are EPDM for insulation and Neoprene for jackets.

Even though both are highly flexible and oil-resistant, the SJOOW has both an insulation and a resistant jacket, and the rubber makes it much more flexible than the SJTOW. That being said, the SJTOW with thermoplastic instead of rubber provides consistency in the implementation with a little more robustness than the SJOOW rubber.

How to choose the right SJTW cables?

There are many applications for SJT cables, especially in the lighting and electrical equipment industry. In addition, if you look at different firms, whether they are categorized as heavy industrial or commercial photography, they mostly use SJT cables because they are such a flexible cable that is much cheaper than other cables available.

There are various numbers of conductors that can be identified for SJTW cables. The more cars, the more strength. You’ll find, however, that the wider cables you’ll see in commercial companies can be as wide as they carry a vast number of drivers. The key rationale for why the cables will get so big is that they need to be longer to accommodate more conductors. While conductors are costly,  companies that do not need a lot of electricity would prefer to use smaller cables.
