Common-Box Bus Duct Features
1. Weak-magnetic steel shell suppresses eddy and circulating currents, cutting heat, losses and short-circuit forces.
2. Top/bottom access holes plus optional side & bottom louvers on high-current indoor units boost cooling and lower temperature rise.
3. Optimised insulator type and spacing keep natural frequencies clear of resonance and reduce electrodynamic stress.
4. Wall-passage partition blocks indoor-outdoor air exchange, eliminating condensation.
5. Snap-in temperature sensors at joints or hot spots enable quick inspection and maintenance.
