Custom Cable Specification Checklist

In the absence of your own cable specification, the following checklist
will assist you to completely specify the cable you want:

1. Number and gauge of conductors.
2. Specification type of wire (military or commercial).
3. Coding of conductors or subcables, striping or numbering, if any.
4. Tape barrier, used as first mechanical protective layer. Can be of Vinyl, Mylar, Tedlar, Polyethylene, or paper-fiberglass laminates.
5. Type of electrical shielding or mechanical armor.
6. % coverage required for electrical shielding
7. Type of outer jacket material.
8. Color of outer jacket, sheath markings.
9. Wall thickness of outer jacket.
10. Necessary physical or environmental requirements, see below.
11. Minimum and maximum overall diameter.

Physical Requirements

• Length, tolerance; Diameter, tolerance.
• Overall tensile strength, if applicable.
• Weight limitations.
• Minimum bend radius.

Evironmental Requirements

• Minimum and maximum operating temperatures.
• Physical abuse: terrain, degree of movement of flexing,
  possible sudden impacts or pressures, etc.
• Surrounding medium: water, oil, sunlight, ice, fuels, air, etc.

Electrical Requirements

• Voltage rating of the conductor insulation.
• Maximum current expected in the conductors.
• Amount of electrical or magnetic shielding required.
• Capacitance requirements.
