SOOW Cable Power Cord Wires
Many materials may be used to make power cords with SOOW cable as long as it is a thermoset material that complies with the various industry standards.
SOOW wire has become the single most popular power cord wire style used for high power (up to 600V) North America power cord applications.
What does “SOOW” mean?
As defined by the NEC (National Electrical Code NFPA 70) and referred to in a variety of UL specifications including UL 817, UL 62 and UL 1581, SOOW simply means:
S: Service use rated up to 600 volts (note: if a J appears in the standard, the wire is only rated up to 300 volts as is SJT wire).
O: The first “O” refers to the rating of outer jacket material and means that it is rated to resist exposure to oil.
O: The second “O” refers to the rating of the inner conductor’s insulation and means it is rated to resist exposure to oil as well.
W: Weather or water resistant.
What are the various thermoset and thermoplastic materials?
NBR or NBR + PVC: Nitrile Butadiene Rubber or Nitrile Butadiene and Polyvinyl Chloride
CPE: Chlorinated Polyethylene
EPM or EPDM: Ethylene Propylene
XLP or XLPE: Crosslink Polyethylene
CSPE or CP: Chlorosulfonated Polyethylene
PVC: Polyvinyl Chloride
TPE: Thermoplastic Elastomer
What are the differences between these materials?
The below chart compares thermoset and thermoplastic materials:
|Flexibility||+ (more flexible)||- (less flexible)|
|Weight||- (heavier)||+ (lighter)|
|Heat Resistance||+ (more resistance)||- (less resistance)|
|Price||-(more expensive)||+ (less expensive)|
|Cut and Tear Resistance||+ (more resistance)||- (less resistance)|
|Abrasion Resistance||+ (more resistance)||- (less resistance)|
|Impact Resistance||+ (more resistance)||- (less resistance)|
|Deformability||+ (more resistance)||- (less resistance)|
|Ability to Glide||- (more glide resistance)||+ (less glide resistance)|
|Oil and Acid Retardant||=||=|
|Ozone and Sun Resistant||=||=|
What material does SPDS use and why?
SPDS has specifically selected the use of a blend of NBR and PVC to produce our SOOW bulk cable because it offer the absolute best value for all of the above properties, especially durability, flexibility, weight and price. We offer the best of thermoset and thermoplastic properties.
SOOW is so popular because it is suitable for so many applications including, but not limited to, industrial equipment, data center equipment, heavy duty tools, battery chargers, household appliances, outdoor power extensions, lighting installations, motor leads, mining equipment, marine equipment, welding machines, fire alarm and temperature control systems, sound equipment, power stations, bus bar drops and heavy duty machinery.
What Industry Standards does SPDS SOOW bulk cable comply with?
|UL: UL 62, UL 817, UL1581, UL 498|
|CSA: CSA C22.2 NO 49-06|
|NEC: National Electrical Code NFPA 70|
|RoHS2 and RoHS|
|REACH (latest version which covers 132 substances)|
|ASTM: American Society for Testing and Materials spec ASTM B3 – 12 and B – 174|
|MSHA: Mine Safety and Health Administration P-136-MSHA Flame Test|
SPDS recommends SOOW style power cord wire whenever ≤ 600V is required and most indoor/outdoor harsh environment applications.
SPDS offers SOOW cable wire in 3, 4 and 5 conductor varieties and in 4, 6, 8, 10 and 12AWG wire thicknesses.
