The industry standard for portable power in demanding environments. Designed for 300V service, this 18/2 SJOOW cord features high-flexibility stranded copper conductors and a heavy-duty, oil-resistant neoprene jacket. Engineered for both indoor and outdoor use, it is built to withstand extreme temperatures, moisture, and chemical exposure, making it the reliable choice for professional tool power and industrial equipment.

Why Choose 18/2 SJOOW Flexible Cord?

The 18/2 SJOOW portable cord is a professional-grade solution for temporary power applications that demand both high performance and superior durability. By utilizing premium EPDM rubber insulation and a rugged thermoset jacket, it offers exceptional resistance to the abuse common on construction sites and in busy workshops.

This 18 AWG, 2-conductor portable cord is the industry standard for light-duty electrical equipment that requires flexibility and durability. It is most commonly used for portable tools, small appliances, decorative lighting, and stage equipment. Because it is rated for hard service, it is also frequently found in industrial control systems and as a power lead for small motors and hospital equipment where the cord must withstand frequent bending and movement.

The letters in SJOOW represent specific engineering standards that define the cord’s capabilities:

  • S (Service): Indicates a flexible portable cord.
  • J (Junior): Rated for 300 Volts (Standard "S" cords are 600V).
  • OO (Oil-Resistant): Both the internal conductor insulation and the outer jacket are resistant to oil.
  • W (Weather/Water): Rated for both indoor and outdoor use, offering excellent resistance to moisture and UV sunlight.

18/2 SJOOW Cord is rated for 10 Amps per conductor. This rating is based on an ambient temperature of 30°C (86°F) per NEC standards for 2-conductor assemblies.

Unlike the solid copper found in household wall wiring (NM-B), 18/2 SJOOW utilizes highly stranded bare copper.

  • Flexibility: The high strand count allows the cord to be coiled, twisted, and moved repeatedly without the copper "work-hardening" or snapping.
  • Durability: Stranding ensures that the cord remains supple even in cold temperatures, making it ideal for outdoor job sites or unheated workshops.
  • Long Life: The flexibility prevents the internal insulation from cracking, which is a primary cause of short circuits in portable power cables.

18/2 SJOOW is built to survive harsh environments that would destroy standard indoor extension cords:

  • Temperature Range: Typically rated from -40°C to 90°C, ensuring performance in extreme sub-zero cold or high-heat industrial settings.
  • Chemical Resistance: The thermoset rubber jacket is designed to resist swelling and degradation when exposed to oils, acids, solvents, and chemicals.
  • Flame Retardancy: The jacket is MSHA-approved (Mine Safety and Health Administration) for flame resistance, providing an extra layer of safety in commercial environments.

This cord contains two insulated conductors, following the standard North American color code for 120V power:

  1. Black: Hot (Line)
  2. White: Neutral
  3. (Note: This is a 2-conductor cord and does not include a dedicated green grounding wire. It should only be used for double-insulated tools or equipment that does not require a frame ground.)

Standard extension cords (often made with PVC or SJT jackets) stiffen in the cold and melt when exposed to oils or heat. SJOOW uses rubber-based materials that maintain their flexibility and chemical resistance, making them the only choice for professional/industrial use.

Yes. The "W" rating indicates the cord is water and weather-resistant, meaning it is designed to hold up against rain, sunlight, and outdoor temperature fluctuations.
