5.2 Cable Joints
If it is necessary to extend the pump supply cable ensure that the cross sectional area
of the extension cable used keeps sufficient cross sectional area to absorb voltage
drop. Ensure that the cable joint is waterproof and secure.
Connect each pair of wires (R-U, S-V, T-W) using a Sleeve Joint and staggering the
joints as shown below in fig. 5.
Primary Insulation layer:
Paste each individual wire joint with glue and wind with a strip of natural rubber.
Then wind with waterproof vinyl.
Secondary Insulation layer:
Gather together all the individual wires into one cable and repeat the above insulating
procedure on the complete cable ensuring that the insulation covers the original cable
insulation at both ends by a minimum of 220mm.
The thickness of the joint must be less than twice the original cable diameter.
5.3 Wet pit ADC installation
In the Wet pit installation, the pump is installed on
the Automatic Discharge Connection (ADC) and
operates completely or partially submerged in the
pumped liquid.
