Product descriptions from the supplier
Description
Customer benefits：
Compliant with IEC standards and F-gas regulation
Compliant with IEC standards and with the EU F-gas regulation (EU) 2024/573.
High ratings up to 2500A. Single busbar modular and compact lowpressure design, based on natural origin gases (SF6 free).
Loss of service continuity LSC 2A and partition class PM*.
Reliable and flexible
Compact and modular design for space optimization.
Very low maintenance required as all high voltage parts are permanently sealed in a gas tank and protected from soiling, humidity, foreign bodies, and other environmental influences.
Due to the low-pressure design, the switchgear can remain in service up to the point of repair, even in the unlikely event of a leak.
The switchgear can be enabled with monitoring and diagnostics (e.g., temperature, gas, partial discharge) to track asset health. Automation and control features based on current and voltage sensors and IEC 61850 protocol allow for customization during the manufacturing phase and varying loads during operations.
Well known and proven vacuum circuit breaker type VD4X.
Outer cone cable termination system.
Safety
High level of operator safety with front, lateral and rear arc protection, certified AFL(R) 40kA 1s (according to IEC 62271-200).
Plug-in busbar technology and the factory-assembled pressure relief duct allows for safe, quick and easy installation at site.
With the switchgear diagram and operation controls on the front panel, no opening of the doors is required for manual operation making the switchgear operator friendly.
Wide range of monitoring and diagnostic features for safe and reliable operations. All switching devices are motor-operated and can be controlled remotely.
Mechanical and electrical interlocks prevent incorrect operation of the switchgear panels.

Q: What’s the difference in the circuit breaker for air-insulated vs gas-insulated?
A:
Air-insulated switchgear circuit breaker is typically removable or withdrawable. The circuit breaker is based on vacuum circuit technology. In the gas-insulated, it is fixed mounted. The function of withdraw is provided by a separate disconnecting switch. Typically, a three-position switch with connected, disconnected, and ready-to-earth position.

Q: What are the maintenance requirements associated with the air-insulated switchgear (AIS) vs gas-insulated (GIS)?
A:
Gas-insulated switchgear requires very low maintenance as all high voltage parts are permanently protected in a gas tank from soiling, humidity, entry of foreign bodies and other environmental influences. Primary, the drives located outside gas compartment require inspection and maintenance. On the other hand, gas-insulated switchgear repair requires additional training (e.g. for gas works) and the replacement or parts may not be as easily. In the air-insulated switchgear visual inspection is recommended in regular intervals, maintenance of power parts is given in installation, operation and maintenance manual (1VLM000363).
Q: What smart solutions are available for ABB’s AIS portfolio?
A:
ABB’s switchgear smart solutions are designed to help our customers make data-driven decisions. Our customers can benefit from a wide range monitoring, diagnostic, automation and control features for their ABB’s air-insulated medium voltage switchgear. Contact our sales team to learn more about ABB’s smart solutions for each of our switchgear.

Ensuring Reliability: A Deep Dive into Transformer MaintenanceIntroductionElectric transformers are the backbone of modern power distribution systems, silently enabling the reliable delivery of electricity to homes, businesses, and industries. As these critical assets age and the demand for uninterrupted power grows, the importance of diligent transformer maintenance has never been greater. This essay explores the essential role of transformer maintenance, highlighting the value of proactive care, the impact of advanced diagnostic technologies, and the traVziman09/03/2025 -
How does a transformer work?Transformer Operation PrincipleA transformer is an electrical device that operates on the principle of electromagnetic induction to transfer electrical energy from one circuit to another. It enables the adjustment of voltage levels within an alternating current (AC) system, either stepping up (increasing) or stepping down (decreasing) voltage while maintaining the same frequency.Working Principle:Basic ComponentsA transformer consists of two coils, known as windings—the "primary winding" connectRockwell09/03/2025 -

Withstand voltage test of high-voltage cablesWithstand voltage test is an insulation test, but it is a destructive test that can reveal insulation defects difficult to detect in non-destructive testing.The test cycle for high-voltage cables is three years, and it must be conducted after non-destructive tests. In other words, the withstand voltage test is performed only after all non-destructive tests have been passed.Most high-voltage cables used today are cross-linked polyethylene (XLPE) cables, which can have large cross-sections and covOliver Watts09/03/2025 -
Analysis of Abnormal Causes of High-Voltage Cable Grounding Circulation and Typical CasesI. Introduction to Cable Grounding Loop CurrentCables rated 110 kV and above use a single-core structure. The alternating magnetic field generated by the operating current induces a voltage on the metallic sheath. If the sheath forms a closed circuit through the earth, a grounding loop current will flow on the metallic sheath. Excessive grounding loop current (loop current exceeding 50 A, more than 20% of the load current, or a ratio of maximum-to-minimum phase current greater than 3) not only aFelix Spark09/03/2025
