SAE - Society of Automotive Engineers.

SBR - A copolymer of styrene and butadiene. Also GR-S or Buna-S. Most commonly used type of synthetic rubber.

SDN - small diameter multi-conductor control cable with a neoprene jacket and nylon sheath over polyethylene insulation.

Secondary insulation - a high resistance dielectric material which is placed over primary insulation to protect it from absorption.

Self Extinguishing - The characteristic of a material that extinguishes its own flame after the igniting flame is removed.

Self-Supporting Cable - any assemblage of conductors which incorporates a steel rope of steel sheath for added tensile strength, thus enabling it to be suspended between widely spaced supports.

Semi-Conducting Tape - a tape of such resistance that when applied between two elements of a cable, the adjacent surfaces of the two elements will maintain substantially the same potential.

Semiconductor - In wire industry terminology, a material possessing electrical conductivity that falls somewhere between that of conductors and insulators. Usually made by adding carbon particles to an insulator. Not the same as semiconductor materials such as silicon, germanium, etc. Used for making transistors and diodes.

Semi-Rigid PVC - a hard semi-flexible polyvinylchloride compound with low plasticizer content.
