SOOW Cords are something you probably come across every day. Use an extension cord to power an air compressor in your workshop? There’s a good chance it’s an SOOW cord. Understanding the SOOW cord meaning is essential for anyone working with electrical equipment, as these versatile cables serve multiple industrial and commercial applications where reliability and durability are paramount.
SOOW cord meaning refers to a specialized type of electrical cable where each letter represents a specific characteristic that defines its construction and capabilities. The acronym SOOW breaks down as follows:
This designation system, established by the National Electrical Code (NEC), provides a clear understanding of the cable’s intended use and protective features. When you see “SOOW” on a cable, you immediately know it’s designed for demanding environments where exposure to oil, weather, and water is a concern.
SOOW cord is exactly what its name indicates. Each letter in the name stands for something specific, creating a comprehensive description of the cable’s protective properties. Therefore, SOOW cord is a service cord that is constructed with an oil-resistant black thermoset polyethylene (CPE) jacket with color-coded synthetic oil, ozone, and water-resistant rubber (EPDM) insulation.
These cables are specifically engineered to handle the harsh conditions found in industrial, commercial, and outdoor environments. Unlike standard electrical cords, SOOW cords are built to withstand exposure to chemicals, extreme temperatures, and physical stress while maintaining electrical integrity.
The superior performance of SOOW cords stems from their multi-layer construction:
Outer Jacket: The black thermoset polyethylene (CPE) jacket serves as the first line of defense against environmental hazards. This material is specifically formulated to resist oil penetration, UV radiation, and temperature extremes.
Insulation Layer: Each conductor is wrapped in EPDM (ethylene propylene diene monomer) rubber insulation. This synthetic rubber compound provides excellent resistance to oil, ozone, and water while maintaining flexibility across a wide temperature range.
Conductor Core: High-quality copper conductors ensure optimal electrical performance and heat dissipation.
The durability of SOOW cord is a result of the components of the jacket and insulation material. Its jacket material makes it weather-resistant. In fact, the components will harden under direct heat, creating a protective shell that maintains its integrity over time. This means that the cord will stand up to aging, abrasion, water, sunlight, and ozone abuse.
The temperature rating is particularly impressive—SOOW cords are safe for operation up to 221 degrees Fahrenheit (105°C) as well as 40 degrees below 0 Fahrenheit (-40°C). This wide temperature range makes them suitable for both hot industrial environments and cold outdoor applications. The insulation material adds to the durability by making the cord resistant to oil as well, preventing degradation from hydraulic fluids, lubricants, and other petroleum-based substances commonly found in industrial settings.
SOOW cords must meet strict industry standards to ensure safety and performance. These cables are typically rated for 600 volts and comply with UL (Underwriters Laboratories) standards, CSA (Canadian Standards Association) requirements, and NEC (National Electrical Code) specifications. The standardized construction ensures consistent performance across different manufacturers while providing users with confidence in the product’s safety and reliability.
While SOOW cords are built for durability, proper maintenance can significantly extend their service life. Regular visual inspections for jacket damage, proper storage to avoid excessive bending or crushing, and protection from sharp objects will help maintain the cable’s integrity. The oil-resistant properties mean that incidental contact with petroleum products won’t immediately degrade the cable, but prolonged exposure should still be minimized when possible.
