Penn Panel specializes in prototype to low volume production of custom fabricated busbars. Using high conductivity copper, we fabricate bus bar assemblies that can handle amperages up to 6000A. We also stock a large variety of insulators from low voltage standoffs to 38kV Porcelain Insulators. Our hipot equipment is used to test the integrity of insulation systems. If you are making repairs or modifications that require copper bus bar, contact Penn Panel today.
