Table 2: Cable wiring diagram

1. Remove the insulating layer without damaging the conductor.
2. Stagger long and short wires.
3. Ensure that no oil, water or any other pollutant exists at the
connection.

or animal shall enter
1. Divide each connector into several strands evenly (no less than 6
ones) and tighten them
2. Cross the two connectors so that the overlapping length will make
the two ends are aligned with the insulating layer

1. Clench each strand. First get one strand from the middle and
make it wind to one end (the wound core wire shall include the
remaining strands) and then make each of the remaining strands wind
successively as well.
2. Follow the same procedure at the other end.
3. Use pliers to tighten the connectors. The best effects can be
achieved by wrapping the connectors with tin.
Note: For other methods, please refer to the attached Drawing 1 and
Drawing 2.

1. First use the black tape to tightly wrap the connector area and
make two layers; do not expose the copper wire head. Please see the
attached Drawing 3.
2. Then use the pressure sensitive tape (self-adhesive tape) to make
a three-layer wrapping, 10mm longer at the two ends should be
needed based on previous layer wrapping. Do not do wrapping until
the length of the tape drawn out is twice the original length.
3. Finally apply the plastic insulating tape (yellow transparent) to make
the last layer wrapping.

1. Properly arrange the connectors of core wires and make a four-
layer wrapping by use of the pressure sensitive tape with two ends
wrapping a length of 30mm on the cable sheath and 10mm longer at
the two ends should be needed based on previous layer wrapping
2. Then make a three-layer wrapping with the plastic insulating tape
with the next layer about 10mm longer than the first layer at the two
ends

An electric arc welded joint is preferred.

2
A joint made by cold welding of casing is also acceptable.

When the first layer of the black tape is made, no copper wire shall be
exposed or the tape shall not be punctured.
