B2 Digi-Bridge

The B2 Digi-Bridge is a fully automatic and highly accurate high-voltage cable insulation and jacket/sheath testing and fault location instrument. Designed for rugged environments, it is housed in a durable IP65-rated pelican-type injection molded case. This one-piece, fully integrated device excels at testing both cable insulation quality and cable sheath integrity. Its standout feature, however, is its ability to precisely pre-locate faults using the proven bridge fault location method. The Digi-Bridge is an indispensable tool for identifying failures in cable insulation or jacket-sheaths with precision and efficiency.
