Cords are an important parts of all industries. Every field needs power and for that power, sources and cables are essential. Choosing which cord is better for your task depends upon many factors. Because the market has many options, people often get confused. This is especially true for those who don’t have enough knowledge about it. The SO cord is one of the most utilized cords around. Stick around to read what this cord is and where they are used.
What Is A SO Cord?
SO in this cord is a term referred to as a type of Service Cord, also known as SOW cable, which tells that the cord is for service applications. This electrical cable’s main purpose is to distribute power and offer connection between equipment in various industrial and commercial settings. The SOW cable is a flexible way of transmitting electrical power from one required point to another.
The cable is durable and constructed with multiple stranded copper conductors. A heavy-duty, oil-resistant outer jacket works as perfect insulation and protection to wire. The durable nature makes SOW cord perfect cable to use in environments where exposure to oil, water, chemicals, and extreme temperatures may occur. Its most applicable use is in temporary power connections in field of construction sites, workshops, factories, and outdoor events.
The identification of SOW cords is also easy, just like other cords in electrical applications. The name consists of one word and one number which indicates their uses and characteristics. In the case of the SOW cord, letter ‘S’ stands for “Service” and is best to use in various electrical service-related tasks.
The next is the number which represents the cord’s voltage rating, means the exact voltage cord handles up to a given number. Both these things help the user to find the right cord for their specific electrical needs.
For example, SOOW cord has voltage rating of 600V, thus safely handling electrical systems with voltage of up to 600 volts. While SJOOW 300 volts can tackle equipment that requires lower voltage.
Note: voltage rating is important and you have to be careful while choosing cord. If you choose insufficient rating cord for higher voltage it can be dangerous and using higher rating is just waste of energy. Thus it is not cost-effective, so you have to pick cord for a system or equipment that matches its voltage requirements.

Difference Between SO and SOOW
Many people get confused between SO/SOW and SOOW and consider them the same thing. But they are not. According to some, both SO and SOOW are different types while the majority believe that SOOW is type of SOW cord. The main difference is due to their construction and use, let’s see them in detail.
SOOW is a specific type of SOW cord, and acronym stands for:
- S: It’s for ‘Service’ which shows cable is used in service applications.
- OO: It’s for ‘Oil Resistant, Oil Resistant’ which means that this cable is resistant to oil. Thus its best application should be in areas which are exposed to oils and greases in common.
- W: It’s for Weather and Water Resistant which means this cord is also resistant to water, thus suitable for use in outdoor and wet conditions.
SO and SOOW have same construction like stranded copper conductors, insulation, and oil-resistant outer jacket. Both are heavy-duty electrical cords. SOOW is also weather-resistant that’s why it’s better to pick for more rugged outdoor environments.
When it comes to difference between SOW and SOOW cords, remember that the latter are just upgraded versions of SO cords. They are, in addition to being oil-resistant, offering added benefit of weather resistance.

As portable power cable, the SOW cords’ most welcoming use is in electrical systems. Overall, they have flexible thermoset rubber jacket, a good one to offer resistance against oil, weather, and abrasion. But quality varies with each type like:
- The most common is SOOW cord, which has heavy-duty thermoset rubber jacket which makes it good to use in industrial, commercial, and construction field. Its main use is in temporary power distribution systems.
- SEOOW cords are very similar to SOOW cords but remember that they have thermoplastic elastomer jackets. They are more flexible and easier to work with in cold weather. Moreover, in addition to being water resistant, they are also resistant to ozone, thus giving extra protection.
- Another one is STOOW cord which is lighter than SOOW cord. Its outer jacket is thinner than latter one. This one is more flexible and easier to handle. Moreover, it’s less expensive than other available ones, but sadly, it’s not as durable as required.
- ST cord can tackle electrical currents of up to 600 volts, thus you can use it in wider electrical applications. Although it is relatively durable and versatile, this version is not as oil-resistant as needed. Just remember to not use it in areas where exposure to oil is maximum.
- SVT cord can efficiently tackle relatively high voltage levels. What makes SVT different from others is its suitability for wet locations because of its moisture-resistant properties. Thus, they are better to use in areas which are always exposed to water or damp conditions. The prominent areas include outdoor lighting, electrical appliances, or work as power tools in damp environments.
Moreover, remember that SOW cords are also available in various conductor sizes and configurations. When it comes to conductor 3 sizes, 10,12, 14 AWG are most common sizes. SOW cords are also available with two, three, or four conductors.
When it comes to SOW cord construction, you will find three main components mainly.
SOW cords have copper conductors which are core of it and carry electrical current. However, they are also made of aluminum conductors but it isn’t as conductive and durable as copper.
Insulation is crucial and for the SOW cord. Makers use Ethylene Propylene Diene Monomer (EPDM) rubber. This rubber is resistant to synthetic oil, ozone, and water. Moreover, it also protects cord from temperatures and environmental conditions.
The cord has an outer layer which is known as a jacket. The SO cord has a thermoset chlorinated polyethylene (CPE) jacket which offers resistance to oil and harsh weather. It protects the inner part of the cord from moisture, sunlight, and other external things that affect its integrity.
