Insulation layer of a power cable
Conductor of a power cable
Strip a part of the insulation layer C of the power
cable according to the cross-sectional area of the
conductor, and ensure that the conductor D of the
power cable is exposed for the length L1.
Route the power cable into the heat shrink tubing A.
Route the exposed conductor of the power cable into
the OT terminal B, and then maintain the OT terminal
close to the insulation layer C of the power cable.

When stripping the insulation layer of a power cable, do not damage the metallic conductor of the power cable.
If the bare crimp terminal is not provided by Huawei, change the value of L1 according to the actual value L of
the bare crimp terminal. L1 = L + (1-2) mm.
After the conductor is routed into the OT terminal, the exposed part L2 of the conductor of the power cable
cannot be more than 2 mm.
