Lead seal is one-time use, to open can only be cut, after repair, take a new lead seal re-sealed. I won't introduce this much. Today I'm going to introduce the lead seal of the meter.

Don't underestimate the lead seal of the ammeter. When the ammeter is out of the factory, it is qualified and sealed with a lead seal, indicating that it can be installed and used. Just like the certificate, another function is to prevent others from disassembling. Just like the warranty paper, you should never open the lead seal of the ammeter in your home. This small lead seal is strictly controlled by the power company. It is on the lead seal of the ammeter. Every number is recorded. If you open the lead seal of the ammeter privately, it belongs to the act of stealing electricity. The lead seal of the ammeter is one-time and can not be sealed again after opening. Every lead seal of the ammeter is unique.
