Product Description

Jelly Filled Underground Armored Telecommunication Cable



Core Construction:

• Conductors: Solid, annealed copper; sizes 19, 22 and 24 AWG

• Insulation: Solid, high density polyethylene, 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: Pairs are assembled together in a single group (25 pairs and bellow);  Or arranged in groups,each group having a color-coded unit binder (over 25 pairs).

• Core Wrap: Non-hygroscopic dielectric tape applied longitudinally with an overlap

• Aluminum Shield: Corrugated, copolymer coated, 0.008" aluminum tape applied longitudinally with an overlap

• Support Messenger: A 1/4", 7 strand, extra high strength galvanized steel wire, fully flooded for corrosion protection

• Jacket: Black, linear low density polyethylene is jacketed in an integral extrusion with the shielded core and support messenger.
