Aerospace Glossary Letter C
Concentricity – In a wire or cable, the measurement of the location of the center of the conductor with respect to the geometric center of the surrounding insulation.
Conductance – The ability of a conductor to carry an electrical charge. The ratio of the current flow to the potential difference causing the flow. The reciprocal of resistance.
Conductivity – The capability of a material to carry electrical current-usually expressed as a percentage of copper conductivity (copper being 100%).
Conductor – An uninsulated wire suitable for carrying electrical current.
Conduit – A tube or trough in which insulated wires and cables are passed.
Connector – A device used to physically and electrically join two or more conductors.
Connector Adaptor – The female connector part that mates two male connectors. There are two types: threaded and bulkhead (flanged).
Continuous Vulcanization – Simultaneous extrusion and curing of elastomeric wire coating materials.
Control Cable – A multiconductor cable made for operation in control or signal circuits.
Copolymer – A compound resulting from the polymerization of two different monomers.
Copper-Clad – Steel with a coating of copper welded to it.
Corrosion – The deterioration of a material by chemical reaction or galvanic action.
Crazing – The minute cracks on the surface of plastic materials.
Creep – The dimensional change with time of a material under load.
Cross-linked – A term denoting intermolecular bonds between long chain thermoplastic polymers, effected by chemical or irradiation techniques.
Crosstalk – A type of interference caused by signals from one circuit being coupled into adjacent circuits.
CRT – Abbreviation for Cathode Ray Tube; common terminology for a video display terminal. Also referred to as VDU or VDT.
CSA – Abbreviation for Canadian Standards Association, a non-profit, independent organization which operates a certification service for electrical and electronic materials and equipment.
C-Track – A cable guide mechanism manufactured of either plastic or metal used in continuous flexing applications.
Cut-Through Resistance – The ability of a material to withstand mechanical pressure, (usually a sharp edge or small radius) without separation.
Cycle Life – The number of repetitive flex motions that a wire or cable can withstand prior to breakdown.
