Application Scenarios and Core Value

Comparison Dimensions VD4 Standard Series VD4/P series
Core positioning The universal standard series Enhanced series specifically optimized for switchgear panels
Target users All medium-voltage power distribution scenarios, including panel manufacturers, EPC contractors, industrial users, and power companies. Panel manufacturers (OEMs), especially those producing fixed switchgear.
Typical applications Power plants, substations, industrial power distribution, infrastructure, ships, capacitor bank switching, and almost all other primary power distribution fields. Fixed switchgear (such as the XGN series), power plant auxiliary power supply, industrial and mining enterprise substations, etc.
Core Values Wide applicability and powerful performance:With over 2 million units installed worldwide, its exceptional versatility and reliability are evident. It offers outstanding performance up to 46kV, 4000A, and 63kA, meeting a wide range of needs from standard power distribution to harsh environments such as marine applications. Safe and reliable "in-cabinet collaboration":By integrating more deeply with switchgear, it enhances the safety and ease of operation of the entire power distribution system. Its core value lies not in higher electrical parameters, but in its "seamless collaboration" with fixed switchgear.
