CHLOROPRENE - A colorless liquid C4H5Cl. Abbreviated as chloro.
CHLOROSULFONATED POLYETHYLENE - A synthetic rubber, made by DuPont de Nemours Co. Resistant to oxidation by ozone, sun, weather, heat, and chemicals, rated 90° C. Abbreviated CP or CSPE. Trade name is Hypalon® which is a trademark of the DuPont de Nemours Co.
CHROMATIC DISPERSION - Different wavelengths travel along an optical medium at different speeds. Wavelengths reach the end of the medium at different times, causing the light pulse to spread. This chromatic dispersion is expressed in picoseconds (of dispersion) per kilometer (of length) per nanometer (of source bandwidth). It is the sum of material and waveguide dispersion.
CHROMEL®-ALUMEL® - The alloy used in making Chromel-Alumel® thermocouple wires. Chromel® is an alloy of nickel and chrome plus nine other elements. Alumel® is an alloy containing nickel, manganese, aluminum, silicon, and nine other elements. Chromel® is nonmagnetic; Alumel® is highly magnetic. Chromel® and Alumel® are trademarks of the Hoskins Mfg. Co.
CHROMIUM - A blue-white metallic element found naturally only in combination and used in alloys and in electroplating.
CIRCUIT (ELECTRIC) - The complete path of an electrical current. When the continuity of the circuit is broken, it is called an open circuit; when continuity is maintained, it is called a closed circuit.
CIRCUIT SIZES - A popular term for building wires sizes 14 through 10 AWG.
CIRCULAR MIL - A term universally used to define cross sectional areas of conductors. It is an area (7.854 x 10 sq. in.) equal to the area of a circle one-thousandth (10-3) of an inch in diameter. As the number of circular mils increases, the size of a wire increases. Abbreviation CM.
CL2 - Abbreviation for Class 2 cable.
CL2P - Abbreviation for Class 2 plenum cable.
CL2R - Abbreviation for Class 2 riser cable.
CL2X - Abbreviation for Class 2 cable, limited use.
