Chamber - Column Coupling
Before coupling the chambers and column, check that the markings on the
breaking chambers correspond with those on the column
The final chamber/column coupling operations should be completed in a
time of  40 min.
NOTE: The coupling operations must be carried out by a min-
imum of two people.
T(max)  40 min
Provide an adequate means of hoisting:
3,000 daN (minimum)
The chamber- column coupling operation can be broken down into a num-
ber of stages:
Step
A Positioning the chamber casing
B Preparing the breaking chambers
C Checking of the insertion resistor
D Preparing the column's corona shield
Preparing the elements required for the coupling opera-
E
tion
F Hoisting and preparing the column
