GLOSSARY OF TERMS | S-Z
  A-B | C-D | E-H | I-R | S-Z
S
Heavy-duty, rubber-insulated portable cord. Stranded copper conductors with separator and individual rubber insulation. Two or more color-coded conductors cabled with filler, wrapped with separator and rubber jacketed overall. 600 V.
SEOW
Thermoplastic elastomer (TPE) insulated conductors. Water flame, oil, abrasion, ultraviolet resistant for outdoor use.
SJ
Junior hard service, rubber-insulated pendant or portable cord. Same construction as type S, but 300 V. Jacket thickness smaller.
SJEOW
ame as SJ, with Thermoplastic elastomer (TPE) jacket and insulated conductors. Water, flame, oil, abrasion, ultraviolet resistant for outdoor use.
SJEOOW
Same as SJEOW, but with oil resistant inner and outer jacketing.
 SJO
Same as SJ, but neoprene, oil-resistant compound outer jacket. Canalso be made "water resistant". 300 V, 60°C, 75°C, or 90°C.
SJOOW
All rubber, oil, water, flame, abrasion resistant in/out jacket. 300 V, -40°C to 90°C.
SJT
Junior hard service thermoplastic insulated conductors with overall thermoplastic jacket, 300 V, 60°C, 75°C, or 90°C. Indoor use.
 SJTO
Same as SJT, but oil-resistant thermoplastic outer jacket.
SJTW
Same as SJT, but outdoor water-resistant outer jacket.
 SO
Hard service cord. Same construction as type S, except thicker oil-resistant neoprene jacket. 600 V, 60°C to 90°C.
SOOW
All rubber, oil, water, flame, abrasion resistant indoor/outdoor jacket. 600 V, -40°C to 90°C.
SOW
Neoprene oil resistant jacketed portable cord, for outdoor use (CS).
SP-1
All rubber, parallel-jacketed, two-conductor light duty cord for pendant or portable use. 300 V.
SP-2
Same as SP-1, but heavier construction, with or withough third conductor for grounding purposes. 300 V.
SP-3
Same as SP-2, but heavier construction for refrigerators or room air conditioners. 300 V.
SPT-1
Same as SP-1, except all-thermoplastic. 300 V. With or without third conductor for grounding.
 SPT-2
Same as SP-2, except all-thermoplastic. 300 V. With or without third conductor for grounding.
 SPT-3
Same as SP-3, except all-thermoplastic. 300 V. With or without third conductor for grounding.
ST
Hard service cord, jacketed. Same as type S, except all-plastic construction. 600 V, 60°C to 105°C.
STO
Same as ST, but with oil-resistant thermoplastic outer jacket. 600 V, 60°C to 105°C.
STW
Same as ST, but indoor/outdoor water-resistant outer jacket.
SVT
All plastic construction. Light-duty vacuum cleaner cord. With or without third conductor for ground purposes only. 300 V, 60°C to 105°C.
Separator
Pertaining to wire and cable, a layer of insulating material such as textile, paper, mylar, etc., which is placed between a conductor and its dielectric, between a cable jacket and the components it covers, or between various components of a multiple-conductor cable. It can be utilized to improve stripped qualities, roundness, and/or flexibility, or can offer additional mechanical or electrical protection to the components it separates.
Shield
A sheet, screen, or braid of metal, usually copper, aluminum, or other conducting material, placed around or between electric circuits or cables or their components to contain any unwanted radiation, or to keep out any unwanted interference.
Spacing
Distance between the closest edges of two adjacent conductors.
Spark Test
A test designed to locate pin-holes in the insulation of a wire or cable by application of high voltage for a very short period of time while the wire is being drawn through the electrode field.
Spiral Wrap
The helical wrap of a tape over a core.
Strand
A single uninsulated wire.
Stranded Conductor
A conductor composed of groups of
wires twisted together.
Tensile Strength
The pull stress require to break a given specimen.
Thermoplastic
A material that softens when heated and becomes firm on cooling. Example: PVC (plastic).
Thermoset
A material that hardens or sets when heat is applied and that, once set, cannot be resoftened by heating. The application of heat is called "curing." Example: rubber.
UL
Abbreviation for Underwriters Laboratories, a non-profit independent organization that operates a listing service for electrical and electronic materials and equipment.
UL 497A
The UL standard covering the basis for UL listing of surge controls for phone lines.
UL 452
The UL standard covering the basis for UL listing of CATV lines.
Voltage
The term most often used in place of electromotive force, potential, potential difference, or voltage drop to designate the electrical pressure that exists between two points and is capable of producing a current when a closed circuit is connected between two points.
VW-1
A flammability rating established by Underwriters Laboratories for wires and cables that pass a specially designed vertical flame test, formerly designated FR-1. Typically used for individual conductors or paralled-type constructions.
