1. SCOPE
1.1
This specification describes a flexible single conductor HYPALON
®
(chlorosulfonated polyethylene) insulated, cotton
braided Telephone Power Cable suitable for general purpose wiring in telecommunications central office power plants.
Cables may be installed in raceways, on racks or trays, or internally in equipment. 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 90
o
C in dry locations or 75
o
C 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 105
o
C AWM and have FT1 (all sizes) and FT4 (4 AWG and larger) flame ratings.
