 crimping. R
 (4) Sleeve shrinking
 -Put the 90 mm (3.5433 in.) KYNAR sleeve EO718 in the correct position on the splice.
 -Shrink the sleeve with the applicable tool.
 -Wait until the sleeve is cold.
 -Put the 110 mm (4.3307 in.) KYNAR sleeve (E0718) in the correct position on the splice.
 -Shrink the sleeve with the applicable tool.
 -Make sure that the sleeves are in the correct condition.

PARALLEL SPLICES - DESCRIPTION AND OPERATION
 _______
1. General The desired result is a connection between several cables through a splice without alterations to the cable electrical and mechanical characteristics. Parallel splices installed on aircraft have the following code :
 -NSA936809RG High Temperature Parallel Splice
 -NSA936808RF Low Temperature Parallel Splice

 B. P/N Characteristics
 (1) Temperature Maximum operating temperature is 260 deg.C (500.00 deg.F).
 C. Connection Procedure
 (1) Wire stripping
 (Ref. Fig. 001)

 -Select the applicable insulation sleeve "B" (length, diameter, temperature of use).
 -Install the sleeve (heat-shrinkable) on the wire before stripping. R - If necessary, select and slide the compensation sleeve(s) NSA937502 R on the cable before stripping.
 -Strip the wires to the length "A" with the applicable tool.
 (2) Crimping procedure and tools R (Ref. Fig. 001, 002, 003)
 -Select the applicable splice according to the wire section.
 ____
NOTE : A table gives the list of wire gauges and the related sections (Ref. 20-32-21)
 -Select the tool and setting applicable for the splice.
 -Make sure that it is in good condition.

 -Position and center the splice in the indenter or between the tool dies. If the brazing seam is visible on the splice, place and center it opposite to the punch.
 -Squeeze the tool handles to hold the splice in the crimping position.
 -Insert the stripped cables in the splice and make sure that all strands are inserted.
 -Move the two handles together or apply pressure to perform the crimping operation. Make sure complete crimping is obtained (ratchet release or automatic opening of dies).
 -Remove the crimped assembly.
 -Make sure that the connection is in the correct condition and that: The cable insulator does not penetrate into the splice barrel. The crimping indents are centered. The stripped conductors do not protrude excessively (visible length
 < 1.5 mm (0.0590 in.)). R - If necessary, shrink the compensation sleeve(s).
 -Slide the insulation sleeve "B" in position and shrink it.
