They are "Magnetically Shielded Conductor
," patent number 6,506,972, issuing on January 14, 2004, and "Magnetically Shielded Assembly," patent number 6,713,671, issuing on March 30, 2004.
Secondary medium voltage switchgear is divided into two separate parts - HV switchgear secondary compact - secondary HV SF6 gas-insulated switchgear with metal housing and compact design with bus bar inside the container filled with SF6 and internal relays, with all poles in metal housing without phase separation and medium voltage switchgear secondary Modules - secondary medium voltage switchgear gas-insulated SF6 metal enclosure in a modular format (each field in a separate gas sandbox) with insulated and shielded conductors
By locating the cross-point switch close to the DUT, 200 conductors were routed 2 feet while only 15 shielded conductors
had to extend the full 10 feet to the test equipment.
