Figure 5-2 Stripping a power cable (OT terminal)
NOTICE
l When you strip a power cable, do not damage the conductor of the cable.
l If the bare crimping terminal is not provided by Huawei, the value of L1 is 1 mm (0.04 in.)
to 2 mm (0.08 in.) greater than the value of L.

NOTE
If you are proficient in assembling OT terminals and power cables, you can obtain the value of L1 by
comparing the part to be crimped with the power cable.
Step 2 Put the heat-shrinkable (A) tubing onto the bare crimping terminal, as shown in Figure 5-3.
