ABB Ability™ GIS for MV - ZX is a digital concept for medium-voltage switchgear. ZX Digital is an enhancement of the existing ZX gas-insulated switchgear portfolio for primary applications. The new gas-insulated digital family is enriching the existing ABB digital switchgear portfolio for medium voltage, which offer the air-insulated digital switchgear, namely UniGear Digital.
The ZX Digital concept relies on following main pillars: Well-proven ZX switchgear (up to 40.5 kV, up to 3150 A, up to 40 kA), state-of-the art sensor technology for current and voltage measurement and advanced communication technology according to IEC 61850 as well as condition monitoring and diagnostics.
Just one communication bus system, which carries interlocking information as well as sampled measured values of voltage signals replaces complex wiring schemes of conventional switchgear. Thanks to continuous supervision of communication on the redundant bus system, ZX Digital offers superior reliability in comparison to a conventional switchgear.
