ZN85 auxiliary handcart designed and produced by us has a screw rod drive mechanism and can be moved easily and avoid damage of the drive mechanism due to misoperation. It applies to the 50Hz and 40.5KV three-phase alternating-current single-bus segmented power systems in KYN61-40.5 armored mobile metallic metal-enclosed switchgears. Used with different primary components, it can realize bus connection, electric energy measurement, and overload protection or short-circuit protection for power equipment and, during system overhauls, functional component and interlocking.
ZN85auxiliary handcart is produced in line with the following standards and codes.
● GB/T 11022-2011 Common specifications for high-voltage switchgear and controlgear standards
● IEC 62271-2007 High-voltage switchgear and controlgear - Part 1: Common specifications
