Conductor:
Solid Soft drawn annealed bare copper
Insulation:
Polyolefin with standard telephone industry color coding
Cable Core Assembly:
Insulated conductors are twisted into pairs varying lays (twist lengths) to minimize crosstalk and meet strict capacitance unbalance limits. Cable containing over 25 pairs are cabled and assembled in sub-units, each identified by color coded unit binders
Shielding:
A corrosion/oxidation resistant, blue tinted ethylene copolymer coated (on both sides) overlapping 0.008 inch thick corrugated aluminum tape shield is applied longitudinally with overall to provide 100% electrical shielding coverage
Messenger Strand:
1/4 inch diameter 7 wire Extra High strength (6.650lb. test strength) galvanized steel messenger strand is integrated within the outer jacket in a "figure 8" configuration. The strand interstices are flooded with an asphaltic sealing compound to prevent possible moisture migration from splicing points. The jacket forms a "web" between messenger and cable thus permitting specialized suspension clamps to grip the jacketed messenger (no stripping needed) without damaging the cable jacket.
Jacket:
Black polyethylene. It is compounded to withstand sunlight, temperature variations and other environmental conditions, including abuse during installation.
Footage Marking:
Footage markings are printed sequentially every two feet along the outer jacket to provide readily accurate records of cable usage and continuous-length reel contents.
