8/3 SOOW Cable- Black

SOOW wires are medium voltage electrical cables designed to help with industrial control systems. The S stands for service wire meaning they relay power from mains to systems. OO stands for water and oil resistance insulation and jacketing while the W infers weather resistant insulation and jacket. So the 8/3 SOOW is an electrical cable with 8 gauge diameter, three conductors with water, oil and weather resistant insulation and jacket. This cable gives uttermost performance between -400C and 900C which is an impressive wide range of temperatures.

The 8/3 SOOW wire conductor is effectively protected from the damaging effects ozone, industrial solvents, abrasive forces, water, moisture, oil and weather. That means it would perfectly fit in almost any work environment. Moreover, it is fire retardant; when fire breaks out, the cable’s jacket hardens into a hard coat which retards the fire hence protecting the conductor, preventing overheating, melting and short circuiting.

8/3 SOOW Conductor

The 8 gauge 3 conductor SOOW Cable has three same-sized conductors made of copper. Copper because it’s a good conductor and more readily available as compared to other conductors. The 8/3 SOOW conductor is annealed; heated steadily so that the resultant conductor is soft and flexible. The three conductors are stranded to give the cable some flexural strength for structural integrity.


The 8 gauge 3 conductor wire has ethylene insulation, EPDM. EPDM is reliable insulation made of saturated group of polyethelene to give rubber with very poor conductivity and permeability. That way, water, moisture or oil cannot infiltrate through the insulator to interfere with the conductor and neither can power flow from the conductor through the insulation hence keeping the cable handler safe. With this protection, the 8/3 SOOW can work in almost any environment. Three conductors are separated with sturdy paper waxes which is a further protection and insulation for the cable. They are color coded in black, white and green.


The cable jacket is made of a thick CPE material which is fire retardant. The fact that it is fire retardant means that the conductor is safe in case of a fire breakout. This cable’s jacket is also resistant to weather, moisture, oil, water, abrasions and solvents so it will keep the cable in good shape for many years of service. 


8/3 SOOW cable is highly flexible mainly because the conductor, the insulation and the jacket are flexible. Annealing makes copper very soft, flexible and easy to terminate. Flexible cables are easy to fix so pulling this cable through ducts or trays is easy because it flexes to conform to the shape of the ducts and trays. The EPDM insulation and CPE Jacket are both tough materials which can withstand forces but are very flexible. They can bend and twist with the conductor without wearing out. The whole system of the 8/3 SOOW portable cable is therefore very flexible and can be folded for easy transportation to storage and installation sites.

Approvals and Certifications

This SOOW wire is tested and certified by a number of international standards organizations as a proof that is has the qualities that the manufactures purports it has. It is approved by the following organizations:

  • NEC 501.140
  • MSHA
  • NEC
  • RoHS


SOOW wires can be used almost anywhere thanks to their flexibility and safety features. The 8 gauge 4 conductor wire carries up to 600 volts of 40 amps which is sufficient for many industrial tools and equipment. The light weight makes it appropriate for portable tools and motor vehicles.

8 gauge 3 conductor portable SOOW cable has a large number of viable areas of application. This is because the cable has features that enable it to withstand rough operating environments. The most common applications include:

  • 600v rated industrial equipment
  • Water purifications systems
  • Generator lead cables
  • Battery lead cables
  • Motorsvehicle
  • Portable equipment.
  • Handyman compressors
  • Control systems
  • Fire alarm connections
  • Instrumentation systems

The minimum length of this wire that you can purchase is a foot while the maximum length is 1000 feet. 1000 feet weighs just 485 Lbs which is light weight compared to many cables.
