Polymer housings are injection molded by using advanced technology. The housing is securely molded over a fibreglass rod using new generation equipments operated by fail proof systems.
Crimping is done by using new-generation, microprocessor controlled equipment to provide consistent, high quality product. This process of crimping is again verified through a series of standard tests before the product is ready to be shipped.
High Voltage Test
At our Laboratory we put our final product through a Power Frequency Voltage Flash over and make sure that it withstands both wet and dry conditions as required.
Thermal Mechanical Test
Low/high temperature chamber is set up which operates between our products are good to -50c and +50C degree C. Further, a hydraulic system with power pack of 20 Ton capacity loading arrangements is provided to the chamber to conduct the design tests on Insulator as per CAN/CSA, ANSI and IEC protocols.
Test for curing characteristics of Polymer compound
At our Testing facility we realize that batch testing is necessary to deliver consistent product quality. A sample from each batch of polymer is tested using ODR (Oscillating Disk Rheometer). The test results reflect cure conditions under constant high pressure and desired temperature
At ASAsoft we ensure product durability and mechanical strength by putting our product to test in a specially designed Universal Testing Machine with a tensile clearance of 1800 mm and computer interface. All our insulators can be tested as per CAN/CSA, ANSI and IEC-61109 and tested for customer’s requirements for mechanical strength.
Resistance to Corona Test
To test the resistance to Corona 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 the combined stress from electrons, ozone, UV and high temperature simultaneously.
UV Resistance Test (ASTM G 154 (Formerly ASTM G 53))
We carry out the UV resistance test by exposing the vulcanized sheet made from Silicon rubber to UV light (315 nm) and dry heat simulating normal day condition. ASTM G154 uses a combination of fluorescent light and water to simulate exposure to sunlight and rain or dew. The sunlight exposure being simulated can either be direct or through window glass.
Test for Hydrophobocity
High end sophisticated camera based instrument is used for measuring contact angle of liquids on solids. This instrument is interfaced to PC. The liquid drop shape analysis makes the instrument an error free one. By measuring contact angle, we can assess the state of hydrophobicity character of Silicone rubber under various conditions.
Fiberglass rod testing & Viscosity test of Resin Mixture
During process control of our quality control department, we collect samples at regular intervals from resin bath to audit the viscosity and to maintain the required viscosity.
We simultaneously also have facility for measuring glass content in fiberglass rods and carrying out Dye Penetration test, Water Diffusion test, Water Absorption test and Specific Gravity test . These are some of the very basic yet crucial tests to assess the quality of the core.
