QUALITY CONTROL TEST
We believe a through testing of components and in process can ensure the quality of this new generation product to give service for years together. The different tests are carried out in our Laboratory.
Mechanical & Physical Tests on our Silicone Compound
- Tensile Strength
- Elongation at Break
- Tear Strength
- Hardness
- Specific Gravity
Electrical Tests on our Silicone compound
- Volume Resistivity
- Break down Voltage
- Tracking and Erosion Resistance Test
Resistance to Corona
- Here a cured sheet from our Silicon compound is put in a cell under corona generating electrodes thereby exposing the Silicon rubber under corona. In this test the Silicon rubber is subjected to combined stress from electrons,oone, UV and high temperature simultaneously.
UV Resistance Test (ASTM G53)
- We are equipped with the facility for exposing the vulcanized sheet made from Silicon rubber to UV light (315 nm) and dry heat simulating normal day condition.
Dye Penetration Test
- It is one of the very basic tests to access the quality of the FRP rod. We regularly carry out this test on our FRP rod.
Water Diffusion Test
- This is a critical test for FRP rod. Through 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:
- Water absorption test
- Specific gravity
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.
