Solid copper bars

Solid copper bus bars are used in electrical panelboard, for power distribution and when bending and processing requirements do not allow to use default fixing connection points.

Solid copper bars

Copper drawn bars are good electrical conductors and are appreciated for their flexibility, strength and endurance. In addition to the electrical panels cabling, Copper Bus bars are used in other electrical equipment for distribution or transmission of electricity, realisation of bus ducts and electric power supply lines of electrical field.
