GENERAL 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.
CONSTRUCTION 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.
