4/4 SOOW wire

SOOW wires and SOOW cables are portable cords; service wires specially designed to supply heavy duty industrial power to different equipment in a commercial systems set up. 4/4 SOOW cable black is a member of the SOOW Cable family. These are service cables with high ampacity, water and oil resistant insulation and jacketing. The cable is appropriate for a very wide range of industrial applications including powering up tools and plants with high voltage power of up to 600v. These cables are classified by size and voltage rating. “4/4” means that the cable is a 4-gauge which describes a medium-sized wire with four conductors.

4/4 SOOW Wire Conductor

This cable is made of annealed stranded bare copper conductor. Naturally, the copper wire conductors are rather stiff and difficult to handle. Annealing is the process of heating the conductor at a controlled temperature and then allowing it to cool down. Annealing makes the conductor a more malleable and foldable. This is important because if a cable is foldable it’s easy to roll and transport from one point to another. Annealing also makes the conductor more versatile and flexible for easy installation.

The conductor is stranded. Stranding means the conductor has a central structural component with other conductors helically surrounding the central wire. This makes the cable so strong and gives the 4/4 SOOW wire a structural element to keep it in shape when installed in ducts cable trays. The stranding is done in accordance with the ASTM B 174 for class K cables. The cable has a capacity of 600v which is pretty high and sufficient for industrial applications.


Ethylene Propylene also commonly referred to as EPDM insulation is used for this cable. EPDM is premium grade insulation so it’s very reliable for protection against environmental factors that would otherwise compromise the performance of the cable. The insulation protects the cable from adverse effects of weather, water, oil and impacts of hard impacts. The main purpose of the insulation is to ensure safety of the user. EPDM does not conduct electricity so even if a handler comes into contact with this cable when it’s under use he won’t be electrocuted so it does a good job in protecting both the cable and the user.

Cable Jacket

The cable jacket is an additional protection for the conductor. Its main purpose is to ensure a conducive operating environment for the conductor. The jacket is made of Chlorinated Polyethylene which effectively resists water, oil, UV light and industrial solvents. Unlike many cable jackets, the CPE has a rare property unique to a few cables; fire resistance. When a fire breaks out, the CPE transforms into a fire resistant compound to keep the underlying conductor safe from any adverse effects that the fire would have on it.

Size, length, weight and ampacity

Cables sizes are graded by gauge. The 4-4 SOOW wire is a 4 gauge wire. A gauge (AWG) is about 0.3 inches diameter so four gauge translates to 0.2 inches. The higher the gauge the smaller the conductor diameter. This cable has four conductor of about 0.2 inches diameter each. The smallest size you can buy from conventional sites is a foot and the longest you can purchase on one go is 1000 feet. The strands measure 133/025, the cable insulation is 0.06 inches thick, a 100 feet weighs 1144 pounds and it can safely transmit up to 60 amperes under normal conditions.

Approvals and Certifications

It is important because certification is a sure of way of establishing that the cable possesses the qualities that the manufacturer claims it possesses. The 4 gauge SOOW Cable is approved and certified by a number of internationally acclaimed standards bodies for use indoors and outdoors in commercial set ups for supply of up to 600 volts, 60 amps. These include

  • NEC 501.140 Class I Div. 2
  • MSHA
  • NEC Article 400
  • RoHS


Versatile cables like this one have very many viable applications. These applications range from moving parts to stationary industrial equipment. The most common applications would include; oil rig wiring system, push button remotes, heavy industrial tools and commercial machinery. Basically, nature of the conductor, the features of the insulation and jacketing makes it a good candidate for industrial applications. Generally, this SOOW portable cord is a tough cable that can withstand very high temperatures, punishing environment and hard impacts. This puts it way ahead of many conventional cables.
