This cable is designed for use as a duct cable in either exchange area service or trunk service. The cable is foam-skin Polyethylene insulated, fully color coded, and fully filled with a filling compound to prevent the penetration and migration of water.
Conduction: Solid annealed bare copper wire, 0.40, 0.50,
0.65 and 0.90 mm (26, 24, 22, 19 AWG) in size.
Insulation: Color coded foam/skin high density polyethylene.
Twisted Pairs: The insulated conductors are twisted into pairs with specified
color combinations to provide pairs identification
Cable Assembly: Cables having 25 or fewer pairs : The pairs are assembled in a single group.
Cables having more than 25 pairs : The pairs are assembled in units, each unit
being identifiable by color coded unit binders.
Identification Tape: A tape, indelibly marked with the following details, shall be laid over the
cable core or under the outer lapping tape (nonhygroscopic dielectric material)
a. Manufactures Name
b. Year of Manufacture (Duration of two years)Or the marking shall be printed on the outer lapping tape. The marking shall appear at intervals not more than 50 cm throughout the cable length.
Filling Compound: The interstices between the pairs are filled with a filling compound.
Core covering: Nonhygroscopic dielectric tape.
Shielding : A corrugated polyethylene coated 0.2 mm aluminum tape is applied longitudinally
with overlap.The tape is flooded with a flooding compound.
Jacket: High molecular weight, low or medium density polyethylene colored black.
Length Marker: Each length of cable shall be permanently
Identified as, manufacturer name, year of manufacturer, type and size of cable,
and sequentially numbered length.The marking shall be printed on the outer jacket.
An alternate method of marking may be used if acceptable to the Client.
OPTION AND OTHER CONSTRUCTIONS
Cables with an inner jacket, with a compartmental screening tape. Cables having a plastic-coated aluminum shield boned to the jacket are available.Cables of other conductor size or having other mutual capacitance than shown in this catalogue are available on request.
