Medium voltage IEC gas insulated primary switchgear (GIS) ZX2

ZX2

Modular gas-insulated switchgear for primary distribution with high technical parameters

Gas-insulated Switchgear for Primary Distribution

Based on SF6, ZX2’s modular structure distributes medium voltage electric power safely and reliably in a variety of demanding utility and industry applications. It complies with IEC, GB/DL, CSA, IEEE standards with UL certification available on request.

Modular Primary Switchgear for all applications

A compact and modular medium voltage switchgear with high technical parameters and ratings built as a three-phase encapsulated and arc-resistant design for single and double busbar applications. ZX2 is equipped with separate gas-filled busbar and circuit breaker compartments.

Rated voltage up to 36 (42) kV
Rated normal current up to 3150 A (with the use of parallel bus systems up to 5000 A)
Rated short-time withstand current up to 40 kA

Customer benefits

Reliable and flexible

Very low maintenance needed as all high voltage parts are permanently protected in a gas tank from soiling, humidity, entry of foreign bodies and other environmental influences.
All panels up to 2500 A are routine tested and gas-filled pressure in the factory – eliminating gas-work onsite – and enabling faster installation. For 3150A panels with large coolers on busbar either transport in an open top container or gas works on site are required.
Compact and modular design and structure for space optimization
Customized low voltage compartment offers ample space for mounting of protection and control devices
Automation and control features through current and voltage sensors and RTUs and monitoring and diagnostics capabilities (temperature, gas, partial discharge, etc)

High technical parameters

High technical parameters and ratings (rated voltage up to 36kv and current up to 3150A - with the use of parallel bus systems up to 5000 A) built as a three-phase encapsulated and arc-resistant for single and double busbar applications.
Loss of service continuity LC2A and partition class PM.

Safe

High level of operator safety with front and lateral arc protection, certified AFLR 40 kA 1 s (according to IEC 62271-200).
Plug-in technology allows for safe, quick and easy installation.
Wide range of monitoring and diagnostic features for safe and reliable operations available. All switching devices are motor-operated and can be controlled remotely.

Additional features

Vacuum circuit breaker type VD4X
Available with inner or outer cone cable termination system
Optional top cable entry available
Integrated pressure relief ducts and optional pressure relief to the outside of the switchgear room
