18/3 SJOOW Wire 200FT 18 AWG 300V SJOOW Cable - Durable Outdoor Cord

In this review of the 18/3 SJOOW Wire 200FT, the bottom line is simple: this heavy-duty 18 AWG, 3-conductor SJOOW cable is built for demanding industrial and outdoor tasks where durability and reliable conductivity matter. The reviewer found the cable especially well suited for portable power runs to generators, welders, lights, and motors because of its oil- and water-resistant jacket and the use of oxygen-free copper conductors that improve conductivity and heat dissipation compared with ordinary stranded wire.

Key Features

• Rugged jacket: The PVC outer jacket resists oil, water, and acid so the cord performs reliably in harsh industrial and outdoor environments.
• Wide temperature range: Rated to operate from -40C to 90C so it stays flexible and serviceable in cold starts and hot operating conditions.
• OFC conductors: Each of the three conductors is made from 41 finely stranded oxygen-free copper strands for improved conductivity and corrosion resistance.
• 3-conductor format: The 18/3 construction makes this cord suitable for portable equipment and power/control circuits where a separate ground conductor is not required.
• 200 ft length: A single 200 ft spool minimizes the need for extensions on site, useful for long runs to generators or temporary power at events.

Who It's For

The cable is aimed at electricians, maintenance crews, rental companies, and event technicians who need a durable, portable power cord for tools, lighting, motors, and temporary distribution in industrial, marine, or construction settings. Its oil- and acid-resistant jacket and stranded OFC make it particularly useful where mechanical flexing, moisture, and chemical exposure are expected.

Those who need a dedicated equipment grounding conductor or a 3+1 cable should look elsewhere, since this product contains only three current-carrying conductors. DIY hobbyists working on low-voltage or finished-home indoor wiring may also prefer a different, code-specific cable type.

Pros & Cons

Pros

• Durable PVC jacket resists oil, water, and acid for reliable outdoor or industrial use.
• Oxygen-free copper strands deliver improved conductivity and heat dissipation over standard copper wire.
• Long 200 ft length is convenient for temporary power runs without multiple joins.

Cons

• Contains only three conductors with no separate ground wire, so it is not suitable where a dedicated grounding conductor is required.
• At 18 AWG, it is not intended for very high current permanent service on large motors or fixed branch circuits.

Our Verdict

The 18/3 SJOOW 200 ft cable is a practical, value-minded choice for portable power in tough environments where flexibility and resistance to oil, water, and chemicals are required. Choose this cord for generators, portable lights, motors, and temporary power distribution when a three-conductor cable meets the job requirements; do not use it where a separate ground conductor is mandated.

Frequently Asked Questions

Does this cable include a grounding conductor?
No. This is a 3-conductor SJOOW cable with three current-carrying conductors and does not include a separate grounding conductor.

Is the cable suitable for outdoor and marine use?
Yes. The PVC jacket is oil, water, and acid resistant and the cord is designed for demanding outdoor, industrial, and marine settings within its temperature rating.

What is the conductor material?
The cable uses oxygen-free copper (OFC) strands, with 41 finely stranded wires per conductor for improved conductivity and corrosion resistance.
