EXTRA HIGH VOLTAGE INSULATORS
The different tests that are carried
out in our Laboratory:
Physical Tests on our Silicone Compound
Study of process
ability and Curing Characteristics at a particular temperature
with the help of Oscillating Disc Rheometer
- The report
from this study helps us to know the processing characteristics
and total spectrum of curing characteristics of our Silicone
rubber compound, which in turn guide the production department
to maintain consistent quality
Electrical Tests on
our Silicone compound
- Break down
and Erosion Resistance Test
- Here a
cured sheet from our Silicone compound is put in a cell under
corona generating electrodes, thereby exposing the Silicone
rubber under corona. In this test the Silicone rubber is
subjected to combined stress from electrons, ozone, UV and high
UV Resistance Test
- We are
equipped with the facility for exposing the vulcanized sheet
made from Silicone rubber to UV light (315 nm) and dry heat
simulating normal day condition.
- We have
sophisticated camera based instrument for measuring contact
angle of liquids on solids. This instrument is interfaced to PC.
Liquid drop shape analysis makes the instrument an error free.
By measuring contact angle, we can assess the state of
hydrophobicity character of Silicone rubber under various
available for carrying out different tests on FRP rod & Viscosity
of Resin Mixture:
of viscosity of epoxy mixture in the impregnated bath is very
important, as the viscosity of resin mixture will control the
impregnation of the bunch of glass fibers. Our quality control
department in their process control collects samples from resin
bath time to time and checks the viscosity and gives their
feedback to the production department to maintain the required
We have the facility for measuring glass content in FRP rods. Our
Quality Control department collects the samples time to time from
production line and measures the glass content.
It is one of the very basic tests to assess the quality of the FRP
rod. We regularly carry out this test on our FRP rod.
This is a critical test for FRP rod.
Though it is quite time consuming, we are carrying out this tests
on our FRP rod on regular basis.
Besides the above-mentioned tests, we carry out the following
tests regularly on our FRP rods:
All these are to convey that we
understand the importance of role of composite insulators in power
transmission and the importance of their long term uninterrupted
performance. We believe a thorough testing of components and
in-process can ensure the quality of this new generation product
to give service for years together.
