SAFETY PADLOCK
The knob can be padlocked in any position by utilizing the appropriate rectangular hole on the positioning-ring
and inserting the shackle of the padlock (6 mm max.) in the corresponding hollow space of the knob (see
figure 1.5). The protection cap made of "Zama" (Zn + Al + Mg alloy), supplied on request, can be padlocked by
utilizing the appropriate holes situated on the tongues external to the base of the cap (see figure 1.6).
CHAPTER 2 – ASSEMBLY OPERATIONS (FOR THE MANUFACTURER OF TRANSFORMERS)
The knob must be inserted only when the 2 milled centering parts are in alignment. One is positioned on the
shaft and the other is positioned on the metallic section of the support (see figure 2.1)
The lid of the transformer can vary in thickness from 2÷8 mm. The knob is self-adjusting and no thickness-
washers are necessary (see figure 2.2).
The components must be inserted in the following order:
1. OR gasket ring
2. Positioning ring
3. Fixing nut
4. Knob
(see figure 2.3)
Position the knob in the insert/extract position countermarked by 2 small arrows next to the number.
3
Example: for a knob with 5 positions, the insert/extract position is position 3 (see figure 2.4).
When you reach the "desired" and correct position, you must press the knob down lightly until the attachment
takes place (see figure 2.5).
A soft "clacking" sound means the attachment has occurred.
When the protective cap is requested, the transformer lid can vary in thickness from 2 + 6 mms.
The knob is self-adjusting and no thickness washer is necessary.
The components must be inserted in the following order:
1. OR gasket ring
2. Cap base
3. Positioning ring
4. Fixing nut
5. Knob
6. Cap (see figure 2.6)

CHAPTER 3. TREATMENT IN THE OVEN AND / OR UNDER VACUUM AND LUBRICATION

It is recommended that the treatment is carried out at a maximum temperature between 100-120 °C for
24-36 hours (see figure 3.1) Contact our technical CAPT office when carrying out drying procedures at higher
temperatures, or when carrying out "special" treatments.
Lubrication and operations
After the treatment, before using the tap changer, you must lubricate carefully all the fixed and moving
contacts of the tap changer, or alternatively, place the tap changer together with its active part in an oil
bath in the transformer-tank. Wait until the tap changer has come down to environment temperature before
performing the first operation (see figure 3.2).
