1-1-02 Specification ROME TELEPHONE POWER CABLE, 600 VOLTS HYPALON® Insulation, Cotton Braid, Gray Saturant and Finish Type RHH or RHW, VW-1, Oil Res ll, Sun Res For CT Use
1. SCOPE 1.1 This specification describes a single conductor HYPALON® (chlorosulfonated polyethylene) insulated, cotton braided Telephone Power Cable suitable for general purpose wiring in telephone central office power plants. Cables may be installed in raceways, on racks or trays, or internally in equipment where the gray finish on the cable harmonizes with the color of other telephone equipment. Cables may also be supplied with a green finish to denote usage as a grounding conductor. Cables are listed by UL as Type RHH or RHW for general purpose building wire applications in circuits not exceeding 600 volts at a maximum continuous conductor temperature of 90oC in dry locations or 75oC in wet locations. Cables are listed by UL as VW-1 and Oil Resistant ll. Sizes 1/0 AWG and larger may be used in cable tray in accordance with Article 336 of the NEC. Cables are also listed by CSA as 105oC AWM and have FT-1 (all sizes) and FT4 (4 AWG and larger) flame ratings. 2. APPLICABLE STANDARDS 2.1 The following standards form a part of this specification to the extent specified herein: 2.1.1 Underwriters Laboratories Standard 44 for Rubber Insulated Wires and Cables. 2.1.2 Canadian Standards Association Standard C22.2 No. 210.2 for Appliance Wiring Material. 2.1.3 ASTM D-2863, latest issue - Minimum Oxygen Concentration to Support Candle-Like Combustion of Plastics. 2.1.4 Bellcore Spec GR-347-CORE Generic Requirements for Central Office Power Wire. 3. CONDUCTORS 3.1 Conductors shall be Class B stranded annealed tinned copper per UL Standard 44. 4. SEPARATOR 4.1 An opaque polyester separator tape shall be applied between the conductor and the insulation. 5. INSULATION 5.1 Each conductor shall be insulated with Rome-HYPALON, a black chlorosulfonated polyethylene rubber compound complying with the physical and electrical requirements of UL Standard 44 for Type RHH or RHW and 105oC AWM requirements of CSA C22.2 No. 210.2. The insulation shall have a minimum LOI of 28% when tested in accordance with ASTM D-2863. 5.2 The average thickness of insulation shall be as specified in UL Standard 44 for Type RHH or RHW. The minimum thickness at any point shall be not less than 90% of the specified average thickness. The insulation shall be applied tightly to the conductor and shall be free stripping. 6. TAPE 6.1 On sizes 6 AWG and larger, the insulation shall be covered with a wrapped opaque polyester tape. 7. BRAID 7.1 A close-weave cotton braid shall be applied over each cable. The braid shall comply with the requirements of UL Standard 44. 8. SATURANT / FINISH 8.1 The cotton braid shall be saturated with a heat, moisture and flame-retardant compound complying with requirements of UL Standard 44. Color of the saturant compound shall be gray. 8.2 The saturated cotton braid shall be coated with a lacquer paint to provide a gray or green color. 8.3 The saturated lacquered cotton braid forming the external finish shall present a uniform external appearance, shall be smooth, dry and free from irregularities and shall not flake-off. 8.4 The saturated, finished cotton braid shall have a minimum LOI of 28% when tested in accordance with ASTM D-2863. 9. SURFACE MARKING 9.1 An ink print legend shall be applied to each cable indicating manufacturer, size, voltage, UL and CSA designations. 10. TESTS 10.1 Completed cables shall be tested in accordance with the applicable requirements of UL Standard 44, CSA Standard C22.2 No. 210.2 and Bellcore Spec GR-347-CORE.
