CABLE CONNECTION & SEALING OF SACRIFICIAL ANODES
5.0 PROCEDURE
Measure & cut the cable for required length.
Remove the insulation of tail cable and polish the conductor strands with emery paper for
soldering with anode core.
Rough the surface of insert and Put the strand on insert surface for silver soldering.
Heat the copper soldering rod by using blow lamp.
Put the heated copper rod on insert and apply flux with clean surface where soldering is to
be carried out.
Cable to anode connection shall be done as per EIL standard by melting the eutectic rod
with the help of heated copper rod and check the continuity between anode & tail cable.
Put PVC pipe on connection as per Approved Drawing.
Apply M - seal around the PVC pipe to prevent leakage of encapsulation materials.
Pour mixture of epoxy & hardener inside the PVC pipe and the total joint to be
encapsulated.
6.0 PRECAUTIONS
Anode tail cable should be of sufficient length to reach up to test station without any joint.
Care should be taken during heat up, cable encapsulation shall not be heated and burned.
Do not use tail cable for lifting anode assembly.
All connection to be check for proper tightening.
