When a submersible pump is assembled one of the most critical things to get
right is the electrical connection that will spend its life under water.
Most submersible bores in Perth have this underwater connection done using a
heat shrink kit. The submersible motor has a factory installed’ “blue lead”
which is connected to the electrical cable that will come all the way up
from the pump to the bore head at the surface. Seen here is the factory lead
first being crimped to the electrical cable and then the waterproof heat
shrink kit is applied. These are a series of sleeves which are essentially
shrunk over the cable joins provided a waterproof connection.

A separate stainless steel cable holds the weight of the submersible pump so
no stress is placed on this electrical joint. Sometimes in old submersible
bores incorrectly joined electrical cables can be a source of trouble. Our
bore electricians are well equipped to diagnose and repair any electrical
problem you may have with your bore or pump. For repair or installation of
replacement submersible pumps in any Perth suburb call us on 92460111 or
