A cubicle is used by high-voltage consumers to draw electricity. Do you know what a cubicle is in the first place? This document, "Comprehensive Proposal on Electrical Equipment (Cubicles)," thoroughly explains what a cubicle is, including the roles of its various components. ◆ This one unit is enough! The industry's first multifunctional remote monitoring device "EneSEE" Achieves all-in-one insulation monitoring, demand monitoring, power monitoring, and generation monitoring. It ensures safety management of cubicles and reduces power costs! ◆ The fear of cascading accidents With old cubicles, it is not uncommon for electrical accidents to occur due to natural disasters such as heavy rain, strong winds, and lightning, which can further lead to cascading accidents... ◆ The necessity of PCB inspection PCBs may be contained within the transformers in cubicles. Disposal of PCBs is mandatory, and failure to dispose of them will result in penalties. Moreover, there is a set disposal period, and the deadline is approaching... ◆ Tips for keeping initial costs down The most concerning aspect is the initial cost. Are there any tricks to keep costs down?

A high-performance electronic breaker is installed to monitor maximum power. With CPU control, it enables the setting of optimal minimum rated current, which was impossible with conventional breakers, allowing for a significant reduction in electricity basic fees by changing the low-voltage power contract from a "load equipment contract" to a smaller capacity "main switch contract." 【Features】 ○ Even with the same equipment and usage conditions, the contract capacity can be reduced, resulting in lower basic electricity fees. For more details, please contact us or download the catalog.
