Mersen laminated bus bars offer uncompromising electrical performance while minimizing EMI, RFI and crosstalk. As data volume and broadband use continue to expand, performance demands increase for high-speed servers, blade servers, network backbone equipment, engineering work stations, and such. Bus bars are designed to efficiently distribute large amounts of electrical current and are the backbone of many electrical systems — able to handle large amounts of current without overheating. Bus bars (also spelled buss bar or busbar) are produced using premium-grade materials such as copper. In electric power distribution, a busbar (also bus bar) is a metallic strip or bar, typically housed inside switchgear, panel boards, and busway enclosures for local high current power distribution, transmission, or switching substations. Most busbars are made out of brass or copper. In most cases, busbars do not contain insulation, but their rigidity is adequate to allow them to be held in the air by insulated pillars.
