3、 Cable Engineers Association I- i FOREWORD ,. X i ICEA publications are adopted in the public interest and are intended to promote product uniformity and quality throughout the industry. They are designed to eliminate misunderstanding between the manufacturer and user and to assist the user in selec
4、ting and obtaining proper products for the particular application. Existence of an ICEA publication does - not in any respect preclude the manufacture or use of products not in conformance with this Guide. Suggestions for improvements in this publication are welcome and should be sent to ICEA, This
5、Guide was developed by the Telecommunications Wire and Cable Standards Technical Advisory Committee whose membership consisted of technical exDerts from the manufacturing, user, and general interest segments of the industry. The members of the ICEA Communications Cable Section, Working Group 647, wh

The coding format given in Section 3.1 of this document should be used to relate cable specifications to the proper cable code
10、. When a manufacturer requires a new code and no existing code can be identified, a written code request, with detailed cable information, should be submitted to the Insulated Cable Engineers Association, P.O. 440, South Yarmouth, Massachusetts 02664, Telephone (508) 394-4424. 3. CODING FORMAT 3.1 C
11、OPPER CABLE IDENTIFICATION CODING SEQUENCE A four-letter coding sequence designates copper telecommunications cables. Use of this coding simplifies cable identification in ordering, manufacturing, identifying, and record- keeping. After these four letters, if required, is a two-letter code known as
12、the outer- protection-covering designation. The numeric pair count of the cablewould normally follow. An example of the coding format typically used for metallic cable is shown below for a 200 pair, 24 gauge solid insulated filled cable utilizing an 80C filling compound with a bonded ASP sheath and
13、unsoldered mechanical outer protection. I Insulation Type Design I The code displayed above would typically be printed on a cable jacket as AMMY UM 200. 2 3.1 .I First Cable Code Letter-Design The first letter in the 4-letter coding sequence identifies generic design criteria or special properties o
14、f cables. 3.1.2 Second Cable Code Letter-Insulation type The second letter in the 4-letter coding sequence indicates the type of conductor insulation used and, if applicable, the filling compound. 3.1.3 Third Cable Code Letter-Conductor Gauge The third letter in the 4-letter coding sequence identifi
15、es the gauge and the type of conductor material. Conductors are solid wires of commercially pure annealed copper. Conductor sizes may be 16,19,22,24,26 or 28 American Wire Gauge (AWG). 3.1.4 Fourth Cable Code LetterCheath Designation The fourth letter in the 4-letter coding sequence identifies the t
16、ype of sheath materials used. Plastic-jacketed cables often have an acronym that describes the sheath constniction. 3.1.5 Outer Protection Code The standard types of outer protection are designated by a two-letter code that follows the four-letter coding sequence. 3.1.6 Pair Count The numerical desi
17、gnation indicates the nominal pair count (the number of spare pairs is not included in the stated pair count). It typically follows the four letter code unless there is an outer protection code.
