NOTE
COMBINED RESIN SILICON BUSHINGS, TYPE CRS IEEEE
Product description
These instructions are applicable to CRS IEEE combined
insulation bushings with rated voltages from 25 kV to 34.5
kV and rated currents from 2000 A to 3000 A.
These bushings are designed to operate with the upper
part in air and the lower part immersed in the transformer
oil. CRS IEEE insulation bushings have been designed and
produced in conformity with the following standards:
• IEEE C57.19.100-1995
• IEEE C57.19.01-2000
• IEEE C57.19.00-2004
• IEC 60137, Edition 6
Installation
CAUTION
The operating and installation requirements described in this
manual must be strictly followed. If not, the device can be
damaged or a malfunction may occur.
Assembly on the transformer tank
Make a hole with diameter D (see Table 5B) in the transfor-
mer tank, ensuring there are no uneven surfaces that could
cause problems for correct operation of the bushing.
The stud bolts for securing the bushing (see Table 5B) must
be placed along a circumference of diameter D1-D2 coaxial
with the hole made previously (Figure 1).
Position the gasket provided (Figure 1).
The bushing must be positioned as shown in Figure 2, apply
a tightening torque of 18 lbft (25 Nm) to fix the nuts on the
flange.
