3.3.3 Tape or braid. The tape or braid shall be free from any substance that may have a
deteriorating effect on the insulation or on the sheath (see 6.4). Further, the tape or braid shall not be
adversely affected by the compounding ingredients of the insulation or sheath.
3.3.4 Sheath. The sheath shall be made of material that meets the performance requirements in
3.3.5 Shielding (type II only). The individual strands for the shielding (see 6.4) shall be made of the
same material as specified in 3.3.1 for the conductor strands. The American Wire Gage (AWG) size of
the individual strands shall be 34.
3.3.6 Separator. The separator shall be made of a fungus resistant material that shall be free of any
substance that would have a deteriorating effect on the insulation or conductor. Further, the separator
itself shall not be adversely affected by compounding ingredients used in the cable construction or
process.
3.3.7 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or
environmentally preferable materials should be used to the maximum extent possible, provided that the
material meets or exceeds operational and maintenance requirements, and promotes economically
advantageous life cycle costs.
3.4 Construction. Cable construction shall be in accordance with the applicable specification sheet
for the Part or Identifying Number (PIN) specified by the acquisition activity. The length of the cable shall
be as specified in the specification sheet or as specified by the acquisition activity (see 6.2, 6.5, and 6.6).
3.4.1 Conductors. Conductors shall consist of individual strands that shall be free from abrasion,
kinks, and flats. The conductors shall be continuous throughout their length except joints in individual
strands shall be in accordance with 3.4.1.3. The conductor shall be intact and in clean condition for
soldering when the separator is stripped from it.
3.4.1.1 Cross section. The cross section of any conductor shall conform to the applicable
requirements specified in table I.
3.4.1.2 Stranding. Stranding of the conductor shall be left or right-hand lay and, at the option of the
contractor, may be bunched, concentric, or rope lay. When an uninsulated portion is cut, the stranding
shall not tend to unlay and the completed conductor shall not tend to spread out.
3.4.1.3 Joints.
3.4.1.3.1 Sizes 0000 to 16. When the conductor is size 0000 to 16, joints shall be made by butt
brazing or twisting strands together. Individual joints shall occur no closer together than one foot. In no
case shall the whole conductor be spliced at one point.
3.4.1.3.2 Sizes 18 and 20. When the conductor is size 18 or 20, joints shall be made by butt brazing.
Individual joints shall be finished so that the conductor diameter is not increased at the point of brazing.
Joints shall not occur closer together than 10 feet. In no case shall the whole conductor be spliced at one
point.
