FAQ

Q: What is the main function of the observation window of the high-voltage cabinet?

A: It is used to safely observe the operation status of the equipment inside the high-voltage cabinet (e.g. circuit breaker opening and closing position), and at the same time to ensure that the operator is isolated from the electrically charged parts.

Q: How high voltage level can the observation window withstand?

A: Standard products withstand voltage levels of 10-35kV, special design can meet the needs of higher voltage (need to provide specific advice).

Q: Do I need to replace the observation window immediately if it is cracked?

A: It must be taken out of service and replaced immediately. Any visible cracks will reduce insulation and explosion safety.

Q：What do I need to pay attention to when installing?

A:Make sure that the sealing strip is intact, the torque of the fastening bolts is in accordance with the standard, and the pressure resistance test is required after installation.

Q:How can I tell that the observation window needs to be replaced?

A:When there are obvious scratches/yellowing/loss of light transmission >30%, aging and cracking of sealing strips, or regular testing of insulation performance is not up to standard.
