Please accept our best wishes for a very Happy New Year
As we bid adieu to 2004, we look at some of the key activities
that were memorable during the year.
In a small way, we had the opportunity to shape up theAPTRANSCO’s efforts in bringing reliability to the
transmission side. Starting in June 2003 with Dow
Corning 5 Compound, that’s now become generic for
arcing and flashover protection of insulators, the success
of the product lined up the job of bringing longer-term
protection to insulators with Dow Corning High Voltage
Insulator Coating – Sylgard HVIC. The scope of the
activity included the supply and apply of coatings to the
Bus Coupler Bay at Kalapaka 400 KV SS.
The entire infrastructure was lined up in terms of
equipments, safety training for working at heights,coating methodologies and over 60% of the job was
completed in 2004. Take a look at some of the pictures
below.
Sylgard HVIC Application
Most of the other industries continued to rely on the time tested
Dow Corning 5 Compound and 3099 Compound.
Project Sales Corp, with the most complete line of sealing
compounds and materials was awarded the job of sealingthe Valve Hall, the heart of a HVDC station against
ingress of dust, moisture, water and smoke. A multi-
pronged strategy was adopted with various materials as
you can see below.
Over 200 equipments including CTs, CVTs, Isolators, pilots,
tension strings, etc were coated with over 500 kgs of Sylgard
HVIC, many at heights above 20 metres. Safety training of the
painters were an integral part of the exercise with Pentasafe Team
from Mumbai providing the fall protection equipment and
training.
In 2005 we look forward to finishing the remaining part of the job
in the 1st quarter.
These product when applied over the
insulators form a hydrophobic layer
that prevents formation of a
continuous path over the insulator
surface.
Formulated with Dow Corning select
phenymethyl fluids with arc resistant
additives, they provide unmatched
protection against flashovers.

The job was carried out over a 4 day period with Dow
Corning 736 High Temperature RTV, Dow Corning 1890Protective Sealer, 3MFiredam 150+, an endothermic
firestopping sealant.
CT Blast at GTPS, Vijjeswaram
When a CT at the Gas Turbo Power Station at Vijjeswaram
blasted, it ripped many an insulator across the switchyard.
Immediate replacements were called for, but sufficient
quantity was not available. Project Sales Corp took up the
onus of fixing as many chipped insulators with Devcon
Wear Resistant Putty followed by a coating of Brushable
Ceramic.
Over the years Devcon brand
epoxy putties are a reliable way
of emergency repairs to many
electrical equipments. These
include insulators, bus bars,
motors, transmission towers, etc.
As we get into 2005, we wish you a very Happy New Year
again and look forward to associating with many of you in
solving more problems, with the use of the most complete
portfolio of maintenance-repair-overhaul consumables
from one source. Explore your options us™. Call us at
