ABB - AC and DC Surge Arresters for Railway Applications

ABB Switzerland is a producer and developer of AC / DC surge arresters for railway installations and applications. We are a high-end specialist in the newest metal oxide technology (both AC / DC) in all fixed and rolling stock installations.

Reliable and effective protection against over-voltages (atmospheric and switching) on contact wires and locomotives is most important in the smooth and constant running of the trains. To this end, ABB offers a wide range of surge arresters specially designed and tested to live up to the very specific requirements for railway applications.

All ABB arresters for railway applications incorporate the latest metal-oxide technology (both AC and DC) and thus offer the best possible protection.

METAL OXIDE TECHNOLOGY AC / DC SURGE ARRESTERS

The electrical and mechanical design of our surge arresters allows them to withstand the particularly tough requirements of railway operation. They satisfy the requirements of A1 / A2 arresters up to VDV paper 525. Their use increases the availability of the power supply and of railway operation.

SILICONE RUBBER HOUSED SURGE ARRESTERS

The housings of all our AC / DC surge arresters are made in a silicone rubber, exclusively developed for ABB. This silicon rubber has proven to be a superior housing material for this kind of electrical apparatus. Excellent shock and pollution resistance combined with easy handling and the elimination of explosion risk result in a lower total cost for the rail system operator.

ABB SURGE ARRESTERS ADVANTAGES

There are many advantages to ABB's AC / DC surge arresters, including:

• Low residual voltage
• Long protection distance
• High energy input capacity
• Stable U-I characteristics even after multiple strokes
• Proof against ageing
• Explosion and shatter-resistant design
• Pollution resistance and UV stability
• Housing resistant to rough handling
• Maintenance free
• Stable against shock and vibration
• High mechanical resistance

ISO CERTIFICATION

ABB railway surge arresters hold the following certifications:

• ISO 9001
• ISO 14001
• OHS 18001
• IRIS-certification

IRIS CERTIFICATION

IRIS stands for International Railway Industry Standard and is a promotion of the Union of European Railway Industries (UNIFE). It is based on the ISO 9001 standard, but also considers railway-specific requests.

This standard is acknowledged by all major system integrators and equipment manufacturers and makes the highest demands in quality issues at present. It represents an internationally harmonised industry quality standard and helps to simplify lengthy procedures.
