Lesson 4/Learning Event 1
- Spaced binding. This binding is intended for vehicle interior wiring in protected
locations, or in junction and control box applications. Cables are bound together with
one-half overlapping turns of tape in spaced intervals. Tape should form 2- to 2.25-inch
wrap lengths space at 8to 12-inch intervals.
- Spaced binding - heat shrinkable tubing. One alternative method for spaced binding
uses sleeving in lieu of tape.
A heat-shrinkable modified neoprene rubber sleeving, MIL-I-23053/1, has demonstrated
suitable low-temperature flexibility (-55C brittleness) in the military environment and
the cables are bound together with 0.75to 1.25-inch lengths of heat-shrinkable sleeving
spaced at 8- to 12-inch intervals.
- Spaced binding - cable ties. Another alternative spaced-binding method uses wire ties or
straps. Cable straps, adjustable, self-clinching, MS3367-1, MS3367-3, MS3367-4, or
MS3367-5 are suitable for this application. Cables are bound together with straps spaced
at 8- to 12-inch intervals.
- Laced binding. Lacing is intended for wiring used in junction and control box
applications. Lacing cord in accordance with MIL-T-43435, Size 3, Type I, Finish B,
Waxed, Color Optional, has performed satisfactorily in the military environment.
- High-temperature binding. This binding method is intended for harnesses used on
engines, transmissions, or other systems where additional protection against high
temperature is required. Cables are covered, or bound together with insulating sleeving.
Sleeving ends and junctions are bound to cables with one-half overlapping turns of tape.
Tape endings must overlap fully.
Insulating sleeving, electrical, Class 200, Type C, Category C or D, MIL-I-3190, has demonstrated
suitable high-temperature and humidity resistance in these applications. Tape 19207-10886484
has demonstrated adhesive qualities that withstand steam cleaning and the oily, high-temperature
environment associated with vehicle power packs.
