Note:
When wrapping up a connector, please wrap up the connector with a layer of insulation tape before
wrapping with the semiconductive adhesive tape for the convenience of removing the tape.
Below is the procedure of waterproof and encapsulation treatment:
1) Clean the feeder connectors or feeder grounding clamp;
2) Stick the end of the waterproof insulation tape to the feeder at the point 2~5cm
from the connector or grounding clamp;
3) Stretch the tape until it is 3/4~1/2 as wide as its original shape. Make sure that
the stretched width is at least 1/2 of the original width, otherwise over-stretching
may damage the molecular structure of the tape and lower its reliability). Wrap
up the feeder spirally upward while maintaining this stretching strength. Make
sure that the overlapping area of adjacent tape layers is 1/2 of the stretched
width, as shown in Figure 2-43.
Caution:
Make sure that the stretched width is at least 1/2 of the original width, otherwise over-stretching may
damage the molecular structure of the tape and lower its reliability
