Switchgea
Development Directions of Switchgear under New Quality Productive Forces
      Enhancing development quality and transitioning from the previous extensive economic growth model to intensive, high-quality development are equally crucial for the evolution of switchgear.         The switchgear industry suffers from severe homogenization, with low-quality products proliferating unchecked through simple repetition, competing solely on price and cost while neglecting quality. This approach consumes vast material resources without regard for sustainability, prioritizing short-term compliance over long-term reliability.

Miniaturizing 36kV Switchgear
Challenges in Miniaturizing 36kV Switchgear
  The miniaturization of switchgear is a common demand in the IEC market. For instance, the standard dimensions for 13.8kV (17.5kV), 1250A switchgear are typically 600mm in width and 2100mm in height, while 3150A versions are generally only 900mm wide.

Low-Voltage Switchgear
What are the common types of low-voltage switchgear?
For applications with limited budget, simple circuits, and no frequent changes, the fixed-mounted GGD is a cost-effective choice.         For applications with high requirements for supply continuity, frequent operation and maintenance, and a large number of circuits (e.g., Motor Control Centers (MCCs) in industrial plants, large commercial complexes), withdrawable types like GCK, GCS, or MNS are preferable.         For high-end projects or where specific brands are required, original series from international brands like ABB MNS, Siemens SIVACON, or Schneider Blokset are typically selected.
