Engineered for extreme fault conditions with 25kA short-time withstand current (3s) and 63kA peak current ratings. Our robust design keeps your distribution network resilient under the most demanding electrical stress.
The withdrawable handcart allows PT and arrester units to be pulled out for inspection and maintenance without disconnecting main power. Its segmented compartment layout ensures effective isolation between functional units.
Built with CNC-bent, precision-welded galvanized steel sheets for exceptional anti-deformation and corrosion resistance. Internal high-purity copper busbars paired with epoxy resin insulation ensure stable conductivity.
Reinforced cabinet framework and anti-vibration busbar supports maintain operational integrity during seismic events. Ideal for earthquake-prone regions to ensure critical power continuity.
