Term Description
SAE Abbreviation for Society of Automotive Engineers
Saudi Arabian Standards Organization (SASO) For standardization in the Kingdom.
SCSI Small Computer System Interface; ANSI standard which defines mechanical, electrical, and functional requirements for interconnection of small computers and peripherals and other small computer systems
Secondary Insulation A high resistance dielectric material which is placed over primary insulation to protect it from abrasion
Self-Extinguishing The characteristic of a material whose flame is extinguished after the igniting flame is removed
Self-Supporting Aerial Cable A cable consisting of one or more insulated conductors (factory-assembled with a messenger) which supports the assemblage and and may or may not form a part of the electric circuit
Self-Supporting Cable Any assemblage of conductors which incorporates a steel rope or 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
Semi-Rigid PVC A hard semi-flexible polyvinyl chloride compound with low plasticizer content
Semiconductor A material that has a resistance characteristic between that of insulators and conductors
Separator A layer of insulating material such as textile, paper, polyester, etc. Used to improve stripping qualities and flexibility and to provide mechanical or electrical protection to the underlying components.
Serve A filament or group of filaments such as fibers or wires that are wound around a central core
Served Wired Armor Spiral wrap of soft galvanized steel wires wrapped around a cable to afford mechanical protection and increase the cable pulling tension characteristics
Sheath The outer covering or jacket of a cable
Shield A metallic layer placed around a conductor or group of conductors to prevent electrostatic interference between the enclosed wire and external fields
Shield Coverage The physical area of a cable that is optically covered by the shielding material (expressed in percent)
Shield Effectiveness The relative ability of a shield to screen out undesirable signals
Shock Test A test to determine the ability of a cable to withstand a violent physical concussion that might occur during handling or use
Signal A current used to convey information, either digital, analog, audio or video
Signal Cable A cable designed to carry current of usually less than one ampere per conductor
Silicone Any class of synthetic materials which are polymers with a chemical structure based on chains of silicon and oxygen atoms, with organic groups attached to the silicon atoms. Used as both insulation and jacket, with operating temperature range of -65°C to 200°C.
Silver Coated Copper A type of copper that is used in high frequency applications where the higher conductivity of silver is desired
Sintering Fusion of a spirally applied tape wrap jacket by the use of high heat to a homogeneous continuum; usually employed for fluorocarbon, non-extrudable materials
Skin Effect The tendency of alternating current, as its frequency increases, to travel only on the surface of a conductor
SNM A cable designed for use in hazardous locations consisting of insulated conductors in an extruded nonmetallic jacket which is then covered with an overlapping spiral metal tape & wire shield
Solid Conductor A conductor consisting of a single strand of wire
Solid PE Polyethylene available in several forms: linear low-density polyethylene (LLDP), low density polyethylene (LDP), medium density polyethylene (MDP), high-density polyethylene (HDP)
Spacing Distance between the closest edges of two adjacent conductors
Span In flat cables, the distance from the reference edge of the first conductor to the reference edge of the last conductor, or the distance between the centers of the first & last conductor expressed in inches or centimeters
Spark Test A test designed to locate imperfections (usually pinholes in the insulation of a wire or cable by application of a voltage for a very short period of time while the wire is being drawn through the electrode field)
