Key Features

1. Flame retardant performance: It has V-0 grade flame retardant performance, temperature resistance > 130℃.

2. Insulation resistance: The insulation resistance of the measuring box is not less than 20MΩ.

3. Electric strength: apply 50Hz/2500V voltage for 1 minute, no arcing, breakdown lightning phenomenon should occur.

4. Acid and alkali resistance: drop 1 mL of acid-base solution with a concentration of 3% on the surface of the box, wipe it off after 1 hour, and there is no crack or delamination on the surface of the box.

5. Anti-static pressure performance 100kg weight (volume 10cm*10cm).

6. Put it in any position of the product for 3 minutes without cracking or damage.

7. Resistance to static extrusion: apply 100kg gravity to the flat metering box, and the metering box has no cracks, peeling, or damage after 1 minute.

8. Climate influence: The product runs under the environment of 30℃±10℃ outside, 75℃ inside and long-term sunlight exposure, or runs continuously for 4 hours at a low temperature of 45℃±3℃, and the box body should not be deformed, Does not crack and maintains transparency.

9. Impact resistance: The product is free-fall test from a height of 2m under the condition that the fixing screw is tightened (without packaging), and the box should be kept intact.

10. Sandbag impact resistance: The 7kg sandbag is freely dropped from a height of 1m for 5 times, and there are no abnormal phenomena such as cracks and breaks in the measuring box.

Key words:

Totally closed management impact resistance Aging resistance High temperature resistance insulation
