Allied Wire & Cable carries an extensive variety of service cord. A service cord is a very versatile piece of equipment. It can be used in commercial, industrial, indoor, outdoor and residential applications.
Our service cord types include SJ, SJO, SJOW, and SJOOW. However, SJOOW has superseded all service cord types. Any SJ, SJO, and SJOW RFQs will be quoted as SJOOW Cable. These service cords are available for purchase online or you can submit an RFQ for large quantity discounted pricing.
Applications of Service Cord
Features of Service Cord
Service Cord features good flexibility in low temperatures, and it is suitable for use in conditions where the cord is not subject to acid, grease, oil, or solvents. Service Cord also has excellent resistance to oil and moisture, good tensile strength, elongation, good aging characteristics, high flexibility, excellent abrasion resistance, water-resistant, and also UL certified for indoor or outdoor use.
Service Cord Construction:
Service Cord possesses conductors that are fully annealed with stranded bare copper per ASTM B-174, insulation from Premium-grade, color-coded Ethylene Propylene Diene Monomer Rubber (EPDM), CPE Rubber or EPR insulation with suitable fillers. It has a black colored rubber jacket or black colored neoprene with a temperature of -40°C to +90°C.
The different letters in each type of service cord designate the characteristics the cord has. The 'S' and 'J' letters in each of these types mean that they are ‘J’unior ‘S’ervice. Junior service simply means that the voltage rating of the cord is 300 volts. A single ‘O’ designates an oil resistant outer jacket, while the double ‘OO’ stands for oil-resistant insulation and an oil-resistant outer jacket. Finally, the ‘W’ stands for weather and water-resistant and is CSA approved for indoor or outdoor use.
Service cords are also rated as heavy-duty, medium-duty and light-duty. These designations are given based on the jacket used on the cord. Service cord with thermoplastic elastomer jackets is considered medium-duty and those with thermoplastic jackets are designated as light duty.
You can tell what type of jacket the cord has by reading the letters as well. A thermoplastic elastomer jacket will have the letter "E", usually after the "S" or "SJ" depending on the service type. A thermoplastic jacket will have a "T" instead of an "E" in the same spot. The absence of an "E" or a "T" means it has a thermoset rubber jacket.
