<h2>Product Range Overview</h2>
<!– /wp:heading –>
<!– wp:list –>
<ul>
<li><strong>HV Switchgear (High Voltage)</strong>: Metal-clad and metal-enclosed switchgear for voltages up to 40.5kV. Featuring vacuum or SF6 circuit breakers, used in primary distribution substations and power plant switchyards.</li>
<li><strong>MV Switchgear (Medium Voltage)</strong>: 3.3kV–12kV air-insulated panels for secondary distribution. Common in industrial parks, large commercial complexes, and renewable energy collection points.</li>
<li><strong>LV Distribution Panels (Low Voltage)</strong>: 400V/690V main distribution boards, sub-distribution panels, and motor control centers (MCC). The workhorses of building and factory power distribution.</li>
<li><strong>Control Cabinets</strong>: PLC-based control panels, synchronization cabinets, and protection relay panels for generator set control and power management systems.</li>

<h2>Technical Standards & Compliance</h2>
<!– /wp:heading –>
<!– wp:paragraph –>
<p>All switchgear assemblies are designed and tested to <strong>IEC 61439</strong> (Low-voltage switchgear and controlgear assemblies) and <strong>GB 7251</strong> (Chinese national standard). We perform type-tested assembly verification including: dielectric (withstand voltage) testing, temperature rise verification, short-circuit withstand strength, and degree of protection (IP) verification. Every unit undergoes routine factory testing before shipment.</p>
