5.7.2 Making Power Cables

Tools used to assemble power cables include: tape, wire nipper, paper knife, hydraulic
pliers, insulating tapes, soldering iron, and solder wire.
To make power cables, proceed as follows:
1) Measure the distance from the input port of the lightning arrester to the
corresponding binding post of the power distribution box according to the cabling
route of power cables and grounding cables.
2) Cut power cables and grounding cables according to the distance measured and
margins required.
3) Cut the insulating cover of each cable head using the paper knife. The length of
the removed cover must be equal to that of the cable lug.
4) Tighten the lug with hydraulic pliers.
5) Coat the lug and the naked cable with insulating tape, as shown in Figure 5-38. Do
not expose the lug and the naked cable.
(1) The interval is not more than 1 mm (0.04 in.)
(2) The naked stubs are covered with cable caps.
