Description
Parameter

This switchgear strictly adheres to a multitude of domestic and international standards. It meets the requirements of national standard GB3906 "3~35kV AC metal-enclosed switchgear," Ministry of Electric Power standard DL/T404 "Technical conditions for ordering indoor AC high-voltage switchgear," and international standard IEC60298 "1kV above 52kV below AC metal-enclosed switchgear and control equipment". Its design not only complies with industry norms but also demonstrates exceptional practical utility.

The XGN66A-12 distinguishes itself with its compact cabinet volume, which is only 50% of that of ordinary switchgear, effectively optimizing installation space. In terms of performance, it boasts circuit breaker capabilities and high reliability. Furthermore, the equipment is equipped with a reliable and straightforward "five-prevention" interlocking mechanism, which significantly enhances operational safety by effectively preventing common errors.

Regarding its main technical parameters, the XGN66A-12 has a rated voltage of 12kV and a rated frequency of 50Hz. The main busbar rated current can be selected as either 630A or 1000A. The equipment's 1-minute power frequency withstand voltage reaches 42kV, and its lightning impulse withstand voltage is 75kV. Both the rated short-time withstand current for opening and closing and the rated short-time withstand current are available at 20kA or 31.5kA, while the rated peak withstand current and rated short-circuit breaking current can reach 50kA or 80kA respectively. The enclosure protection
level is IP2X, and its standard dimensions are a width of 900mm or 950mm, a depth of 950mm, and a height of 2300mm.
