tion. Maybe we always pay attention to large oil and gas, big chemical industry project. We should eyes to
project impressed current system uses sha-llow buried bed ground type high silicon iron anodes as auxiliary
anodes. Pow-er system is high frequency switch transformer rectifier. The long-term CuSo4 reference electrode
as feedback signal electrode. There are 6 testing pile used for monitoring the efficacy of cathodic protection.
When all system are operation, the production of the whole gas pipeline cathodic protection effect is good.
