Joint Protection Block (Rheostatic) BSZ(R) for Underground Steel Structures

BSZ(R) are designed to provide joint protection of parallel or converging, as well as intersecting underground steel structures and utilities by regulating the parameters of electrochemical protection and are used as part of control and measuring points for electrochemical protection system (EPS), and separately. Method of regulation - manual, type of regulation - smooth (variable rheostat), rated direct current - from 1 to 30A, Resistance of rheostat 0.25, 0.5, 30 Ohm. The number of independent channels of regulation - up to 4 (for placement in the instrumentation).
