190-00906-01 GTX 23 Installation Manual
Rev. C Page B-4
3. Connect a Flat Braid (Item 6) to the shield exposed through the window of the prepared cable
assembly (Item 4) from step 2. The Flat Braid should go out the front of the termination towards
the connector. It is not permitted to exit the rear of the termination and loop back towards the
connector (Figure B-2). Make this connection using an approved shield termination technique.
NOTE
FAA AC 43.13-1B Chapter 11, Section 8 (Wiring Installation Inspection Requirements)
may be a helpful reference for termination techniques.
Preferred Method:
Slide a solder sleeve (Item 5) onto the prepared cable assembly (Item 4) and connect the Flat Braid
(Item 6) to the shield using a heat gun approved for use with solder sleeves. It may prove beneficial to
use a solder sleeve with a pre-installed Flat Braid versus having to cut a length of Flat Braid to be used.
The chosen size of solder sleeve must accommodate both the number of conductors present in the
cable and the Flat Braid (Item 6) to be attached.
Solder Sleeves with pre-installed Flat Braid
A preferred solder sleeve would be the Raychem S03 Series with the thermochromic temperature
indicator (S03-02-R-9035-100, S03-03-R-9035-100, S03-04-R-9035-100). These solder sleeves
come with a pre-installed braid and effectively take the place of Items 3 and 4. For detailed
instructions on product use, reference Raychem installation procedure RCPS 100-70.
Raychem recommended heating tools:
• HL1802E
• AA-400 Super Heater
• CV-1981
• MiniRay
• IR-1759
Individual solder sleeves and Flat Braid
Solder Sleeves:
Reference the following MIL-Specs for solder sleeves.
(M83519/1-1, M83519/1-2, M83519/1-3, M83519/1-4, M83519/1-5)
Flat Braid:
If the preferred Raychem sleeves are not being used, the individual flat braid selected should
conform to ASTMB33 for tinned copper and be made up of 36 AWG strands to form an
approximately 19-20 AWG equivalent flat braid. A circular mil area range of 1000 to 1300 is
required. The number of individual strands in each braid bundle is not specified (e.g.
QQB575F36T062).
NOTE
Flat Braid as opposed to insulated wire is specified in order to allow continuing air
worthiness by allowing for visual inspection of the conductor.
