INSULATED FLEXIBLE BUSBAR

Certifications & approvals

UL (cURus)

Description

SFI series insulated flexible bus bars are made from 2 to 12 electrolytic copper foils of more than 99.9% purity with thicknesses from 0.5 mm to 1 mm. They are the ideal choice for multiple applications including power transportation, connection of electrical equipment and transformers, managing to provide various functions such as connection, shaping, insulation of conductors and integration of insulated supports in a single solution. Busbars with widths from 9 mm to 50 mm are protected by a durable extruded PVC sheath, while those with widths from 63 mm to 80 mm and 100 mm have protection consisting of a special heat-shrink sleeve. They are designed to be bent by hand quickly and easily, without requiring a tool each time. They can be drilled accurately and easily using MFB 13-40 and MFB 50-63 drilling jigs, which are designed to allow for on-axis drilling with diameters of 8, 10 and 12 mm. The busbars are available in various sizes to fit connectors with different sized coupling flaps, thus being able to meet every installation requirement in a versatile way.
