SUGGESTED WORKING VOLTAGE - Usually refers to the AC voltage that can be applied between adjacent conductors.
SUPER HIGH FREQUENCY - See frequency band.
SUSCEPTANCE - Symbol B. The imaginary part of the admittance,
Y, which is given by:
Y = G + iB
where
G is the conductance and
i equals
. For a circuit containing both resistance,
R, and reactance,
X, the susceptance is given by:
B = -X / (R2 + X2)
SV - Vacuum cleaner cord 18/2, 300 volt, light duty rubber, portable.
SVO - Same as SV except with Neoprene® jacket. Neoprene® is a trademark of the DuPont de Nemours Co.
SVT - Same as SV except non marking plastic jacket.
SWEEP TEST - A method to determine the frequency response of a cable by generating an RF voltage whose frequency is varied at a rapid constant rate over a given range. A test commonly made on coaxial cables.
SWEPT COAX - Coaxial cable which has been checked by the sweep test and certified by the manufacturer.
SWITCHBOARD WIRE - High temperature insulated wire such as TA or AVB, used to wire switchboards and control apparatus. It is heat, flame, and corrosive vapor resistant.
SYN. RUB. - Abbreviation for synthetic conductive rubber.
SYNTH - Abbreviation for synthetic.
T - The old UL designation for switchboard wire insulated with thermoplastic lead wire.
