EAP-8 (PD-AP-A) Outdoor Telephone Cable

Cable Construction

Technical Data

1 - Conductor	:	Electrolytic annealed solid copper (CCITT Yellow Book Vol. III-2-G.541 B article, IEC 28 and ASTM B 3).
2 - Insulation	:	Color coded solid polyethylene insulation (BS 6234 Type 03 - ASTM D 1248).
3 - Stranding	:	Pairs are assembled into 10 pairs units. Groups having 25, 50 or 100 pairs are stranded together.
4 - Wrapping	:	A non-hygroscopic and dielectric polyester tape is applied on the cable core longitudinally or helically.
5 - Screen	:	Both sides are coated with copolymer coated flat aluminum tape over cable core longitudinally for screening.
6 - Messenger Wire	:	Galvanized steel messenger wire (ASTM A 475-66T).
7 - Outer Jacket	:	Linear low-density or medium-density, UV resistant black polyethylene outer jacket (ASTM D 1248).
