24、rements covering the safety of single and multiple coaxial and coaxial/optical-ber cables for the distribution of radio frequency signals such as employed in a community antenna television system, and for supplying low-energy power at a potential not exceeding 60 volts to equipment directly associat

25、ed with the signal distribution. These are power-limited cables and are of the following types for installation and use as the CATV cables specied in Article 820 and other applicable parts of the National Electrical Code (NEC), NFPA 70. Electrically nonconductive material separates each optical-ber

26、member from the rest of the cable. a) PLENUM CABLES Type CATVP (coaxial) and Type CATVP-OF (coaxial/optical-ber). These cables are for installation as specied in Section 820.179(A) of the National Electrical Code, ANSI/NFPA 70 in a duct, plenum, or other space used to transport environmental air wit

27、hout the cable being enclosed in raceway in that space. b) RISER CABLES Type CATVR (coaxial) and Type CATVR-OF (coaxial/optical-ber). These cables are for installation as specied in Section 820.179(B) of the National Electrical Code, ANSI/NFPA 70 in vertical runs in a shaft or for vertical runs that

28、 penetrate more than one oor. c) GENERAL-PURPOSE CABLES Type CATV (coaxial) and Type CATV-OF (coaxial/optical- ber). These cables are general-applications commercial cables for use as specied in Section 820.179(C) of the National Electrical Code, ANSI/NFPA 70. d) LIMITED-USE CABLES Type CATVX (coaxi

29、al) and Type CATVX-OF (coaxial/optical- ber). These are limited use cables as specied in Section 820.179(D) of the National Electrical Code, ANSI/NFPA 70. 1.2 This Standard does not specify the impedance or other signal-carrying characteristics of these cables. This Standard does not cover tests for

30、 the signal-carrying performance of these cables. 1.3 Armored cables are covered by interlocked metal strip or a smooth or corrugated metal sheath with or without a jacket over the armor. Cables for encasement in concrete, mortar, other masonry, plaster, or the like have metal armor and a jacket ove

31、r the armor. Cables for direct burial in the earth (see markings in 1.8) are subject to a 1000-pound crushing test. Cables for direct burial are not required to be armored. Cables for direct burial that are armored have a jacket over the armor. All other cables (unarmored, at or round) have an overa

32、ll jacket. Some overall jackets incorporate a nonmetallic messenger. A metallic messenger may be joined to the cable jacket by an interconnecting web. 1.4 Cables of a CATV type do not have a voltage rating. 1.5 Cables of materials that qualify for temperatures above 60C (140F) are marked with a temp

33、erature rating of 75, 90, 105, 125, 150, 200C or 250C (167, 194, 221, 257, 302, 392F or 482F). Temperature marking is not required for cables that qualify for a temperature rating of 60C (140F).

34、FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 1.6 Cables that contain one or more electromagnetic shields in addition to the outer conductors of the coaxial members (these shields are identied as additional in 9.1) are not required to be marked to indicate the presence of the addit

35、ional shielding. A shielded cable that is marked has shielded on the tag and either on the overall cable jacket or legible through the jacket. 1.7 Cables that qualify for exposure to sunlight (720-hour sunlight-resistance test see 26.1) have the designation sun res or sunlight resistant on the tag a

36、nd either on the overall cable jacket or legible through the jacket. 1.8 Cables that qualify for burial directly in the earth (1000-pound crushing test see 29.1) have the designation dir bur , direct burial ,o rfor direct burial on the tag and either on the overall cable jacket or legible through th

37、e jacket. 1.9 Optical performance is not evaluated. Cables with optical bers are to have a tag marking in accordance with 10.3 and 38.1(d). Where there are conductive parts in an optical-ber member or in a group of such members, a tag marking 36.1(e) indicates the presence of these parts. 1.10 These

38、 requirements do not cover antenna-rotator or other coaxial/electrical cables - that is, coaxial cables with additional conductors for electric-light, power, control, non-power-limited re-alarm, Class 1, Class 2, or Class 3 circuits. 1.11 Smoke and ame tests are as follows for the cables covered in

39、these requirements: a) PLENUM CABLES All Type CATVP and Type CATVP-OF cables are tested for smoke and ame characteristics as specied in Smoke and Flame Testing of Plenum Cables, Section 22, which references the National Fire Protection Association Standard Method of Test for Flame Travel and Smoke o

40、f Wires and Cables for Use in Air-Handling Spaces, ANSI/NFPA 262. A cable that complies exhibits a maximum ame-propagation distance that is not greater than 5 ft, 0 in or 152 cm, a peak optical density of smoke produced of 0.50 or less (32 percent light transmission), and an average optical density

41、of smoke produced of 0.15 or less. b) RISER CABLES Jacketed Type CATVR and Type CATVR-OF cables are tested for ame- propagation characteristics as specied in Flame Testing of Riser Cables, Section 23, which references the Standard for Test for Flame-Propagation Height of Electrical and Optical-Fiber

42、 Cables Installed Vertically in Shafts, UL 1666. A cable that complies exhibits a ame- propagation height under 12 ft, 0 in or 366 cm and attains a temperature no higher than 850.0F (454.4C) at a height of 12 ft, 0 in or 366 cm. c) GENERAL-PURPOSE CABLES Jacketed Type CATV and Type CATV-OF cables ar

43、e to comply with one of the two 70,000 Btu/h (20.5 kW) vertical-tray ame tests specied in Alternative Vertical-Tray Flame Tests of General-Purpose Cables, Section 25. The cable manufacturer is to choose one of the following tests: 1) The UL test referenced in 25.1.1 25.3.2. These paragraphs apply th

44、e test method described as the UL Flame Exposure (smoke measurements are not applicable) in the Standard for Vertical-Tray Fire-Propagation and Smoke-Release Test for Electrical and Optical-Fiber Cables, UL 1685. 2) The FT4/IEEE 1202 test referenced in 25.1.1 and 25.4.1. These paragraphs apply the t

45、est method described as the FT4/IEEE 1202 Type of Flame Exposure (smoke measurements are not applicable) in the Standard for Vertical-Tray Fire-Propagation APRIL 21, 2009 COMMUNITY-ANTENNA TELEVISION CABLES - UL 1655 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WI

46、THOUT PERMISSION FROM UL and Smoke-Release Test for Electrical and Optical-Fiber Cables, UL 1685. A cable that complies is eligible to be marked FT4/IEEE 1202 or FT4 on the surface or on a marker tape as indicated in 37.1(h). d) LIMITED-USE CABLES All Type CATVX and Type CATVX-OF cables are subjecte

47、d to the VW-1 ame test specied in VW-1 (Vertical-Specimen) Flame Test of Limited-Use Cables, Section 24, which references the test method described as the VW-1 (Vertical-Specimen) Flame Test in Section 1080 of UL 1581. These cables are not marked VW-1 . 1.12 These requirements do not specify or test

48、 for the electrostatic/electromagnetic performance of a shield. 2 Units of Measurement 2.1 In addition to being stated in the inch/pound units that are customary in the USA, each of the requirements is also stated in units that make the requirement conveniently usable in countries employing the vari

49、ous metric systems (practical SI and customary). Equivalent - although not exactly identical - results are to be expected from applying a requirement in USA or metric terms. Equipment calibrated in metric units is to be used when a requirement is applied in metric terms. 3 References 3.1 Wherever the designation UL 1581 is used in this wire standard, reference is to be made to the designated part(s) of the Reference Standard for Electrical Wire
