14、OOR USE POLYOLEFIN INSULATED COMMUNICATION CABLES SECTION 1: GENERAL 1.1 SCOPE: This Standard covers design requirements for poly- olefin insulated communication cables for aerial, duct, and buried applications with and without internal screening. The construction and prformance requirements for the

15、 following types of cables are included: Type A: solid insulated and non-filled Type F: Type CF: cellular insulated and filled solid insulated and filled While the ultimate method of use and area of utilization is left to the discretion of the end user, the recommended areas of application of each c

16、able type are: Areas of Application* Underground Cable Type Aerial (in Ducts) Buried A R S* N F S R R CF S R R *R = Recommended for use S = Suitable for use N = Not recommended for use * when properly pressurized Standard pair counts in which these cable types are normally supplied are given in Appe

17、ndices A and B. 1.2 CABLE DESIGNATIONS: Specific cable constructions shall be identified by referencing the cable type and shield designation shown in Table 1. For self-supporting cables having an integral messenger, the designation “F8“ shall be added after the shield identification. For cables con

18、taining an internal screen(s), the letters llS“ shall be added at the end of the cable designation.

Cable Type F-5C-F8 is a solid insulated, filled cable having a corrugated, 5 mil copper shield with an integral messenger. Cable Type CF-ARSR-IS is a cellular insulated, filled cable having corrugated, resin coated alum

22、inum and steel shields with an internal screen(s). Cable Type A-AF-F8-IS is a solid insulated, non-filled cable having a flat, resin coated aluminum shield with an integral messenger and internal screen(s). - 2- ICEA S-56-434 83 7007014 0000444 03T 1.3 UNITS: U.S. customary units are employed in thi

23、s Standard. Their approximate SI equivalents are included for information only. 1.4 REFERENCES: See Section 6 for a complete list of titles and dates of ASTM Standards and other standards to which reference is made herein. 1.5 QUALITY ASSURANCE: It is the responsibili-ty of the manufacturer to estab

24、lish quality assurance procedures which will ensure tha.t the product will meet the requirements of this Standard on a continuing basis. It is not intended that a complete testing program be carried out on every length of conductor and cable. When the purchaser wishes to specify acceptance tests or

25、other quality procedures, it is essential that agreement be reached between the purchaser and the manufacturer at the time of ordering. SECTION 2: CABLE CORE CONSTRUCTION 2.1 CONDUCTORS 2.1.1 Each conductor shall be solid, annealed copper and shall meet the requirements of ASTM B 3, except that the

26、requirements for “Dimensions and Permissible Variations” shall be waived. 2.1.2 The sizes of the conductor and their nominal diameters are given in Table 2.

The joints sh

28、all be as small and as smooth as is consistent with good commercial practice and shall be free from sharp projections. Other methods of jointing may be used when mutually agreed to by the manufacturer and the purchaser. 2.1.4 Any section of conductor that includes a factory joint shall have a tensil

29、e strength not less than 85% of the tensile strength of an adjacent section of the solid conductor without a joint. 2.1.5 When a factory joint is made in an insulated conductor, the joint shall be insulated to meet the requirements of Paragraph 2.2.3. 2.2 2.2.1 INSULATION The polyolefin insulating m

30、aterials used shall be such that the requirements of this specification will be met. The insulation shall be solid for Type A or F cables and cellular, with or without a solid dielectric skin, for Type CF cables. The solid dielectric skin over the cellular insulation may or may not be the same polym

31、er as the cellular material. All conductors in each reel of cable shall have the same type of insulation. The manufacturer shall notify the customer as to which insulation material will be used. Insulating materials for cellular insulation may have a blowing agent added to the base resin. Base resin

32、s which may be used include: a) Natural crystalline propylene/ethylene copolymer conforming to the raw material requirements for Type II - 34000-D, per ASTM D 2146. b) Natural high-density polyethylene conforming to the raw material requirements for Type III, Class A, Category 4 or 5, Grade E9, per

33、ASTM D 1248. c) Natural medium-density polyethylene conforming to the raw material requirements for Type II, Class A, Category 4 or 5, Grade E4, per ASTM D 1248. 2.2.2 Colored polyethylene and colored crystalline propylenelethylene copolymer insulating grade materials removed from or tested on the i

34、nsulated conductor removed from the finished cable shall meet the performance requirements of Paragraph 5.4.1. 2.2.3 Repairs to the conductor insulation during manufacture are permissible. The repaired insulated conductor shall be capable of meeting the electrical requirements of Sub-section 5.1. -4

36、herwise specified below. 2.3.1.1 Except as otherwise noted, the “Table of Extended Limit Chips“ defined in Appendix C shall be used. 2.3.1.2 For chromatic colors, there is no V+ (light) limit for yellow, and there is no C+ limit for any color except brown. In these cases, any color above the minimum

37、 limit is acceptable if all other requirements are met. 2.3.1.3 For neutral colors, there is no V+ (light) limit for white and no V- (dark) limit for black. 2.3.1.4 For neutral colors, chromaticity deviations from the neutral centroid may be in any hue direction. Limits of deviation are specified fo

38、r a series of hues surrounding the neutral centroid at specific chroma levels. (A visual color standard meeting these requirements may be obtained from the Munsell Color Company, Inc., 2441 North Calvert Street, Baltimore, Maryland 21218.) -5- 2.3.2 ICEA S-56-434 83 m 9007034 0000447 849 m The insul

42、rdance with Paragraph 2.5.4. 2.4 FORMING OF PAIRS 2.4.1 The insulated conductors shall be twisted into pairs. 2.4.2 The length of pair twists shall be designed to enable the cable to meet the electrical requirements specified in Sub-section 5.1. - 6- ICEA S-5b-Li34 83 m 90070It4 0000448 785 D 2.4.3

43、The average twist length of any pair in the finished cable shall not exceed 6 inches (150 mm). 2.5 FORMING OF CORE 2.5.1 In cables having 25 pairs or less, the twisted pairs shall be assembled in layers to form a substantially cylindrical core. Adjacent layers may be cabled in the same direction or

44、in opposite directions. Cables having 25 pairs or less may also be composed of subgroups in lieu of the concentric layer construction. 2.5.2 In cables having more than 25 pairs, the twisted pairs shall be grouped, each group being bound by non-hygroscopic and non- wicking threads or tape. Each group

45、 shall contain not more than 25 pairs, excluding spare or service pairs. When desired for lay-up reasons, the basic 25-pair groups may be divided into two or more subgroups called units. Each unit in a particular 25-pair group shall be bound with binder threads or binder tapes of the colors indicate

46、d in Table 4 for its particular 25-pair group. The pair count shall be consecutive from 1 to 25 as given in Table 3 through the units in a group. 2.5.3 The binders may be threads or tapes and shall be colored to indicate the sequence of groups for pair identification. Binders shall be applied with a

47、 lay length of not more than 4 inches (100 mm) . 2.5.4 The colors of the binders and their significance with respect to pair count shall be as shown in Table 4. Each color shall be readily recognizable as the basic intended color and shall be distinguishable from all the other colors. -7- ICEA S-5b-
