Proof of insulation property

Barrier fire resistance test:

After spraying a flame with a temperature of 1000°C on the front side of the sample for 5 minutes, measure the temperature on the back side (the flame temperature can be adjusted according to the customer's needs).

Fire resistance test of the bars:

After wrapping the mica tape on the bar, check if the insulation performance is maintained in conditions of 1KV/1000°C/5Min (the voltage, flame temperature and spraying time can be adjusted according to customer requirements).
