Cable tree Combination of individual cores or cables tied together with nylon ties, spirals or hose sheathing. The form of the harness is created when joining the wires, as the various consumers in the device and system circuits are physically separated and the connection with the individual cables makes constant branches necessary. Cable type letter code Identification of cables according to their design, nominal cross-sec- tion and number of cores, nominal voltage and conductor shape, which results in specific combinations of predetermined letters and numbers. For rules and standards, each of the letters and numbers has a specific meaning. Cables for hand-held machinery Handheld device cables are connecting and extension cables for power tools used in the open air or in enclosed spaces (e. g. ÖLFLEX ® 540 P/CP, ÖLFLEX ® 550 P, ÖLFLEX ® 400, ÖLFLEX ® 500 P, ÖLFLEX ® SF ... at Lapp). Caloric load values Caloric load is the energy that is released when cables and other build- ing materials are burned. Campus The campus or primary wiring establishes the connection between the various buildings within a structured wiring system. CAN Controller Area Network. Result-controlled communication system. As a generator of information, this reports to all connected nodes. Capacity Electrical unit of measure, measured in Farad, or electrical unit of measure V x A = Watts. Carrier frequency The frequency of the oscillation whose amplitude, phase or frequency is influenced by a signal. Carrier frequency, hook-up wire In carrier frequency systems, they are used to transmit signals. Up to 120 carrier frequency channels can be simultaneously transmitted in a cable. CCC Abbreviation for China Compulsory Certificate. Products requiring certification can only be imported to China, sold in China or used in Chinese business activities after the relevant CCC certification has been requested and granted. Canadian Electrical Code See → CEC

CEBEC Abbreviation for Comité Electronique Belge – Belgian certification body. CEC Abbreviation for the Canadian version of the US National Electrical Code (NEC). CEE Mark for the European standards institution: International Commission on Rules of Electrical Equipment. CEI Abbreviation for Commission Electrotechnique Internationale – Inter- national. CENELEC Abbreviation for Comité Européen de Normalisation Electrotechniques (Europe). Central filler The core is a design element onto which the other design elements are attached. Characteristic impedance Apparent impedance of an electronic quadrupole; it is made up of the Ohmic resistance and the frequency-dependent resistances of inductances and capacitances. The impedance of a cable represents the ratio of the voltage waves advancing in a direction to the current wave moving in the same direction. Common values are 100, 120 and 150 Ohm. It is important that the impedance of the cable corresponds to the input/output impedance of the connected equipment. Chromatic dispersion Grouping of wavelength-dependent effects which lead to a bandwidth limitation, such as waveguide dispersion and sheath dispersion. Circular Mil (CM) Measurement for conductor cross-sections in 1/1000 inch (0.001”) from circuit diameter. Cladding Cladding is the glass layer which surrounds the core of the fibre optic cable. Clamping range Cable diameter range for which the assured properties of a cable gland apply. CNOMO Abbreviation for Comité de Normalisation des Moyens de Production. Commission for the standardisation of machine tools and tools used in the French automotive industry. With fibre optic cables, the plastic layer on the surface of the sheath for preserving the original surface condition. Coating Coating is a form of mechanical surface protection. It is a primary plastic layer which is applied directly to the sheath glass for fibre optic cables. Central element See → Core.

CE Abbreviation for Communauté Européenne (European Community).

CE marking Comprises the “CE” symbol and indicates a product′s compliance with all applicable EU directives. CE indicates that the natural or legal entity which carries out or initiates the connection is satisfied that the prod- uct meets the requirements of all relevant harmonised standards and has been subjected to all mandatory conformity assessment proce- dures.
