MRJ series busbar spacer plate

The MRJ Series Busbar Spacer Plate is designed to maintain fixed clearance between phase busbars in switchgear, substations, and power distribution panels. It prevents short circuits caused by conductor movement, vibration, or thermal expansion. Made of high-strength insulating material (engineering plastic or epoxy glass) with stainless steel or galvanized hardware, it offers excellent electrical insulation, arc resistance, and long-term stability. The plate features pre-drilled holes for easy bolted installation between busbars. Available in various thicknesses and hole patterns to meet different voltage and current requirements. Reliable and maintenance-free, the MRJ series spacer ensures safe power distribution, reduces fault risk, and improves system reliability under demanding conditions.
