Copper Bus Bars
Copper bus bars are used in a number of electrical applications, such as: in the production of switchboards, transformers, socket panels.
BUS BAR PROPERTIES
Copper flats’ chemical, physical and mechanical properties, tolerances and/or limitations comply to variety of standards, as for example EN 13601, JIS H 3250/JIS H 3140, ASTM B 187. Their production is monitored throughout all stages with the application of management system certified by Lloyds Register as complying with the requirements of standards ISO 9001:2008.
