I. Overview 
GG-1A (F) Anti-error fixed high-voltage Switch equipment used in power distribution stations for industrial and mining enterprises,AC three-phase 50 Hz, voltage 3 ~ 10 KV single bus system as a receiving and distribution of electric power use. GG-1A (F) mechanical procedures misuse of anti-lock sequence anti-error high-voltage switch equipment allocated to improve the product. 
As the switch equipment simple structure, large volume, after the installation of anti-error load divide or close isolation switch to prevent operators getting into the charged segment; prevent charged articulated ground; prevent the grounding line with a isolation switch; Prevent the misuse divide or close breaker, a five errors operating functions. So easy to maintenance, installation and production, can also prevent misunderstanding and reliable operation to ensure that equipment and personal safety.
