YH-SSD1 Solid-state decoupler is a pipeline AC interference protection and lightning protection equipment in Cathodic protection. It is widely used in the discharge protection of AC stray current, AC fault current and lightning impulse current in various cathodic protection systems.
YH-SSD1 Solid-state decoupler is a pipeline AC interference protection and lightning protection equipment in Cathodic protection. It is widely used in the discharge protection of AC stray current, AC fault current and lightning impulse current in various cathodic protection systems.
The product features low-impedance full conduction characteristics for AC currents coupled on pipelines, effectively reducing the conducted AC interference voltage on the pipeline. Meanwhile, it can provide DC isolation for meeting the requirements of confining the pipeline's DC potential within a reasonable threshold range. In the fault state of inductive lightning or single-phase short circuit of power line, it can effectively discharge the lightning impulse current and AC fault current from the protected structure, and play a protective role for pipeline facilities and personnel.
The product adopts metal shell, fully waterproof sealing structure, to satisfy complex field environmental conditions, and it is easy to install and maintain on site.
