5.6.2 Handling of ssis silicone rubber insulator parts
SSIS (Solid Shielded Insulation System) components are insulated
with silicone. All conductors, terminations and covering devices
must be inspected for damage or defects prior to operation.
All SSIS silicone insulator surfaces must have no
•
Bubbles
•
Scratches
•
Visible damage
•
Foreign material contaminants
•
Evidence of wear
If any surface contamination is noticed on any SSIS component,
it must be cleaned. Remove any dirt, oil or grease on any silicone
insulator using a soft clean, lint-free wipe;
Clean silicone rubber insulators using a special wet cleaning wipe,
furnished as part of the SSIS hardware kits. Apply medium force to
clean the gray area of the silicone rubber insulator where it connects
to the bus. Never wipe outside of the gray area.
Use a dry, soft, clean lint-free wipe to remove excessive cleaning
solution. The solution may cause a slight expansion of the silicone
rubber, so any cleaned silicone parts must be air-dried for at least 15
minutes.
Apply silicone grease evenly to the insulator and silicone rubber part,
according to
Table 10. Silicone grease application guide
Part
Silicone grease amount
SSIS bus and bus joints
About 20g
SSIS bus plug
About 10g
Cable tee connector
About 20g
Voltage transformer, voltage sensor, lightning
arrester, test tube and cable plug
About 10g
Clean and dry the contact surface of the socket and the silicone
rubber part (the cable socket and bus insulator may also need
cleaning). Apply another thin layer of silicone grease.
Assemble the cleaned conductors and couplings immediately.
5.7 Assembly
XGIS vertical sections are shipped individually, for assembly into
lineups at the project site. Attaching the vertical sections together
according to the following instructions provides mechanical strength
and is required for the XGIS seismic rating.
See
for detailed assembly instructions.
5.7.1 Drawings
XGIS switchgear are furnished with project drawings specific to the
project and client. Refer to the project drawings for details of the
equipment and its installation.
5.7.2 Assembly instructions
Refer to
for information on attaching AFLR sections, and
for information on attaching AFL sections. Following the
figures are checklists of attachment instructions including hardware
requirements.
