SOLDER - A metal or metallic alloy used when melted to join metallic surfaces; an alloy of lead and tin so used.
SOLDERABLE NYLON LITZ - Litz wire made up of soldereze strands with a nylon serve overall.
SOLDEREZE - Magnet wire insulated with polyurethane base enamel.
SOLID CONDUCTOR - A conductor composed of one wire. Generally 18 AWG through 6 AWG, used where flexibility is not required.
SONAR - Acronym from sound navigation ranging. A method of detecting and locating underwater objects by transmitting a pulse of sound energy, usually ultrasonic, then measuring the return “reflected” echo.
SP SHIELD - Abbreviation for silver-plated shield.
SP-1 - Lamp cord, parallel, all rubber, two conductor, 300 volt.
SP-2 - Similar to SP-1 except heavier insulation.
SP-3 - Similar to SP-1 except heavier insulation, also may have a ground.
SPACE FACTOR - Given values in coil winding for amount of space available.
SPARK TEST - A test given to wire or cable to determine if there are defects in the insulation. A semi-destructive test, in that it will find weak spots in insulation by a spark breaking through thin spots or pinholes in the jacket when a high voltage potential from the conductor to an outside source is applied. Where these sparks emanate, the cable is cut, thus shortening the cable. This test should only be run once on a wire or cable.
SPC - Abbreviation for silver-plated copper. Also abbreviated as S.
