At least 10 times as the diameter of the conductor.
To touch the Electric Pump, please cut off
the power supply first.
14. When the Electric Pump is operating, its cable head or plug board shall not be put into
water; when such submersion is necessary due to the addition of a cable, the connection shall be
sealed strictly to prevent water seepage and electrical leakage. pply in case that the Electric
Pump is to be relocated or touched, so as to avoid any accident.
1.Remove the insulating layer
without damaging the conductor.
2.Stagger long and short wires.
3.Ensure that no oil, water or any
oth er polluta nt ex ist at th e
connection.
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 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 plier to tighten the connectors. The best
effects can be achieved by wrapping the
connectors with tin.
4.Remark: 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 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.

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.
