Flexible insulated bus bars Flexible insulated busbars consist of several layers of uncoated or tinned copper strips and are insulated with highly flexible PVC compound with extrusion technology. They are excellently suitable for high current connections inside switchgears, switchboards or other electro technical installations. Technical data of flexible insulated busbars: Ø UL758 certified (E336413). Ø CE certified. Ø SGS certified: RoHS compliant. Ø Operating temperature: -30℃ to +105℃. Ø Operating voltage: 600Vac/750Vdc; 1000Vac/1500Vdc. Ø Voltage withstand performance with 15min / 50Hz AC: n between flexible insulated busbar and earth: ≥15kV. n between two flexible insulated busbars: ≥30kV. Main features of flexible insulated busbars: Ø Easy assembly: it could be easily bended and fixed with hands or easy tools. Ø Possibility of reducing sizes of the equipment: n Due to favorable thermal radiation properties, the flexible insulated busbars can handle heavier current loads than solid busbars of the same cross-section. Ø Lower temperature rise on the flexible insulated busbars than on normal copper bars. Ø High flexibility: no problem with vibrations or thermal expansions. Application of flexible insulated busbars: The flexibility of the bars makes it possible to install into difficult equipment or small places very easily. They can be particularly well used as connectors in switchgears and between transformers, switching devices and prefabricated power networks.
