ZX2

ZX2, up to 40.5 kV (SF6), is a modular medium voltage switchgear for high demanding and harsh applications in primary distribution.

FOR PRIMARY DISTRIBUTION AND ALL APPLICATIONS

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.

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 40,5 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

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

CUSTOMER BENEFITS

Reliable and flexible

<ul> <li>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.</li> <li>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 3150 A panels with large coolers on busbar either transport in an open top container or gas works on site are required.</li> <li>Compact and modular design and structure for space optimization</li> <li>Customized low voltage compartment offers ample space for mounting of protection and control devices</li> <li>Automation and control features through current and voltage sensors and RTUs and monitoring and diagnostics capabilities (temperature, gas, partial discharge, etc)</li> </ul>

High technical parameters

<ul> <li>High technical parameters and ratings (rated voltage up to 36 kV and current up to 3150 A - 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.</li> <li>Loss of service continuity LC2A and partition class PM.</li> </ul>

Safe

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