1.2 Design Concept and Product Positioning


The design concept of the series product is "safety, precision, durability". We will strive to provide customers with a low-voltage current transformer that has high measurement accuracy, convenient installation, and resistance to all kinds of harsh industrial environments. Whether it is a traditional distribution cabinet, a new energy project, or complicated mining equipment, the MSQ series can always be perfectly integrated and serve as an important role.


2. Core advantage: Why choose Heyi MSQ?


2.1 High precision and high reliability, the measurement result isn't worse than a millimeter


Accuracy is the lifeline of transformers. A series of precision grades such as 0.2, 0.5, and 1.0 are contained in the MSQ series to meet different needs from standard metrology to high-precision control. Even within a wide current range of 5%-120%, our low-voltage current transformer can strictly control errors within the standard so as to ensure authenticity and reliability for each data acquisition and provide a solid data foundation for energy management and system diagnosis.


2.2 Robust in structure, flexible in installation and suitable for different on-site requirements


The MSQ series adopts high-strength materials and optimizes the structure. It has enough internal space for the windows, which is convenient for installing large section cables or busbars. Designated to make the installation a lot easier and to save much time in construction, it greatly reduces labor costs. In the meantime, different situations can be equipped with various size specifications ranging from MSQ-30 to MSQ-125, whose current ratio ranges from 30/5A to 6000/5A, so as to ensure the matching under any existing or future installation scenes of the low-voltage current transformer solutions.
