HFS-12 semi-insulated solid insulation switchgear is suitable for 12KV distribution systems. It is a type of secondary distribution ring main unit that encapsulates the arc extinguishing chamber, conductive connections, disconnector, grounding switch, and main busbar, among other primary electrical circuits. The PSR employs three-position technology and consists of independent standard modules, featuring manual and electric operation functions. By optionally integrating intelligent controllers and other related equipment, it can achieve varying levels of control measurement, protection, and "four remote" functions. Product features include: 1) The solid ring main unit uses vacuum arc extinguishing, with all live parts sealed, achieving a fully insulated and fully enclosed structure; 2) Independent visibility of the working positions of the three phases; 3) Demonstrates clear capabilities in environmental friendliness, intelligence, safety, and flexibility.
