When you strip a power cable, do not damage the conductor of the cable.
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.

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 5-24.

Step 3
Put the OT terminal B onto the exposed conductor, and ensure that the OT terminal is in good
contact with the insulation coating C, as shown in Figure 5-24.
