Materials Insulating base moulded in SMC (fiberglass). Stainless steel terminals. Tin-plated brass d.c. jumpers. Connecting bars in tin-plated brass. Characteristics Plate sectioning for measuring purposes. Balancing resistor can be installed instead of d.c. jumpers (see ACCESSORIES). Used for shunting dielectric joints in open, closed versions or with variable balancing resistors. Applications For electrical connections between several pipes at one junction or in parallel to extend cathodic MPE/SB2 MPE/SB2 protection or to measure and monitor reciprocal interference.
