1. Center conductor
The center conductor shall be copper clad steel with a minimum tensile strength of 440 MPa and appropriate conductivity to meet the electrical characteristics indicated in Table No. 1 and Table No. 2.
2. Dielectric
Gas injected foamed polyethylene; it shall meet all applicable requirements of ASTM D 1248, shall be an insulating grade virgin polyethylene and shall not contain reground, reprocessed or recycled materials. It shall be applied concentrically and bonded to the center conductor.
3. Shield Construction
Laminated Shielding Tape (LST). The LST shall be constructed of two aluminum foils laminated to a strength member and a bonding resin on one side. The LST shall overlap the dielectric circumference by 10 percent minimum.
4. Braid Wire
The braiding wire shall be a round aluminum wire consisting of 34 AWG (0.0063 ± 0.0003 inches), (0.160 ± 0.01 mm) using an aluminum alloy of 5056, 5154, 5154A, or 5954.
