2、e. The requirements for acquiring the product described herein shall consist of this specification sheet and MIL-DTL-24643. Construction, Non-Watertight First - Copper conductor, coated or uncoated (see table I for size). Second - Separator may be used at manufacturers option where required to provi

3、de free-stripping insulation. Third - Thermoset insulation (see table I for wall thickness). Standard identification code applied by Method 1 or Method 3. NOTE: A colored tape may be used on Size 23 and larger. If identification Method 1 is used, insulation color shall be black. Fourth - An optional

4、 reinforcement on Type LSSHOF, Size 23 and larger. Fifth - The specified number of conductors (see table I) shall be cabled together with a left-hand lay as required for the completed cable to meet the twisting and bending endurance tests. On multi-conductor types, fillers may be used as necessary t

5、o form a firm well-rounded assembly; and the cabling sequence shall be consecutive. Sixth - An optional binder. Seventh - Cross-linked polyolefin jacket (see table I for thickness).
