Environmental Testing Chamber
Our unique environmental testing chamber can simulate fog, freezing rain and icing conditions continuously, while monitoring the performance of insulation for test voltages of up to 350 kV. Our facility accommodates contamination testing of external insulation under standard and non-standard conditions.
By simulating a wide range of possible environments we are able to subject components to accelerated conditions that provide accurate assessment and evaluation of component qualification.
These tests are of particular interest to utilities interested in the performance characteristics of various insulators. The test results can be used to determine the best insulator for a specific utility application in their unique region. Icing tests on outdoor grounding and disconnect switches can be done to evaluate mechanical performance in harsh conditions.
Tracking Wheel Test Facility
Our tracking wheel test facility enables the tracking and erosion tests on polymeric insulators that are required by various national and international standards. This facility can also be used for accelerated aging tests on insulation materials.
