Telephone Cable

Standard:bt cw11281198
capacity:50000 coilsweek
the steel tape armor provides increased mechanical protection and gopher resistance
conductors:solid annealed copper
insulation:dual insulation consisting of an inner layer of foamed polyolefin surrounded by a solid polyolefin skin, color-coded in accordance with telephone industry standards
twisted pairs:insulated conductors are twisted into pairs with varying lay lengths to minimize crosstalk core assembly:
25 pairs and less; pairs are assembled together in a single group
more than 25 pairs: pairs are arranged in groups, each group having a color coded unit binder
1200 pairs and larger are mirror image color code.
Filling compound: the entire core assembly is completely filled with etpr compound , filling the interstices between the pairs and under the core tape core wrap: dielectric tape applied longitudinally with an overlap shield: corrugated, copolymer-coated, 0.008’’ al tape applied longitudinally with an overlap
jacket: black, linear low density polyethylene
