BAIJIAN - Third party testing organization
Insulation rubber pads need to undergo a voltage resistance level test before they can be put into use in the market. Generally、 users require insulation rubber pads to have a test report. So what are the testing items for insulation rubber pads? BAIJIAN will give you a brief introduction today. What are the items included in the inspection of insulation rubber pads? Generally、 the inspection items in the insulation rubber pad inspection report include: 1. The appearance and size of the insulation rubber pad; 2. The hardness of the insulation rubber pad; 3. The tensile length and elongation at break of the insulation rubber pad; 4. Permanent deformation of insulation rubber pad at constant extension (150%); 5. Reduction rate of tensile strength of insulation rubber pad during hot air aging (70 degrees * 72H); 6. Water absorption of insulation rubber pad; 7. Electrical insulation performance experiment of insulation rubber pad、 including voltage resistance experiment and breakdown voltage experiment. 8. Appearance inspection; National standard testing standard for insulation rubber pads: National standard for insulation rubber pads: HG2949-1999 "Electrical insulation rubber sheets". Requirements: Voltage level/power frequency withstand voltage/duration High voltage/15 kV/1min Low voltage/3.5 kV/1min Test routine configuration: (1) 5KV insulation rubber pad thickness: 3mm Specific gravity: 5.8KG/m2 Color: red、 green、 black (2) 10KV insulation rubber pad thickness: 5mm Specific gravity: 9.2KG/m2 Color: red、 green、 black (3) 15KV insulation rubber pad thickness: 5mm Specific gravity: 9.2KG/m2 Color: red、 green、 Black (4) 20KV insulation rubber pad thickness: 6mm Specific gravity: 11KG/m2 Color: red、 green、 black (5) 25KV insulation rubber pad thickness: 8mm Specific gravity: 14.8KG/m2 Color: red、 green、 black (6) 30KV-35KV insulation rubber pad thickness: 10mm 12mm Specific gravity: 18.4KG/m2 22 KG/m2 Color: red、 green、 black. Explanation: When used in the area of live equipment、 wet cloth or metal foil should be laid on the insulation rubber pad above and below during the test、 and it should be 200mm smaller than the surrounding area of the tested insulation rubber pad. The voltage should be continuously and evenly increased to the voltage value specified in Table 8、 maintained for 1 minute、 and observed for any breakdown phenomenon. If there is no breakdown、 the test will pass
