3EQ Surge Arresters:
Your Reliable, Sturdy and Economic Choice
3EQ surge arresters are virtually indestructible. While their tube design provides the highest possible mechanical strength and enables them to support high bending moments, the silicone rubber insulation is ideal for outdoor applications in severe environmental conditions. No matter how tough the environmental or operating conditions may be, our 3EQ arresters assures a 100 % reliable pressure relief performance, they provide the ultimate in protection. They are break-proof and retain at least 75 % of their mechanical strength even after pressure relief. They provide the greatest stability, even in earthquakes.

Surge Arresters are an essential aid to insulation coordination in electrical power supply systems. Valuable equipment can be protected against lightning- and switching overvoltages.
If basic rules are kept, modern Metal Oxide Surge Arresters offer complete protection against overvoltages. In addition they offer a failure rate of nearly 0% and a lifetime of more than 20 years.
Costs of Surge Arresters in electrical power supply systems are less than 1% of the worth of the equipment they protect.Costs of Surge Arresters in electrical power supply systems are less than 1% of the worth of the equipment they protect.
High availability and low costs of Surge Arresters facilitate new applications like Surge Arresters for transmission lines. As the result Surge Arresters convince with a quality improvement of electrical power supply systems.

3EP porcelain housed surge arresters Experience is most essential, when it comes to reliability in Medium and High Voltage applications. Since 1929 Siemens have been manufacturing High Voltage surge arresters with porcelain housing – for standard and specialized applications. Our permanent research and development and the concerted know how in our factory give our 3EP surge arresters a leading edge in over voltage protection. The cost-effectiveness of our products is underscored by uncompromising quality ensuring the long service life and reliability of each application. In general, our arresters are used to protect high voltage equipment in substations, e. g.
transformers, High Voltage Direct Current (HVDC) systems or all kinds of compensation systems for electric power networks. However, apart from the area of standard applications, Siemens can offer customized surge arresters for virtually any application (see diagram 1) from 12 kV up to 800 kV.

Even small overvoltages can disable sensitive electronic equipment, computer networks and computer-controlled production systems in fractions of a second. For protection against overvoltages which can result from lightning or switching processes in electrical supply networks, OBO offers a wide range of surge and lightning arresters for the German and international markets. These include not only devices to protect AC networks of various voltage levels, but also special systems for data lines and telecommunication devices, and protective modules for process measurement and control systems.
With the new LightningControllern, OBO presents innovative lightning protection systems with patented multi-carbon technology in the new VBS catalogue. The first modular spark gap for perfect integration into distribution systems. The great advantage of the new units is that they have a fully encapsulated housing. This means no more arcing! This eliminates the risk of fires in the distribution box due to sparking.
The OBO range of systems for external and internal lightning protection is also complete. All components have passed the tests imposed by the Lightning Protection and EMC Technology Centre in Menden and have the corresponding test marks and certificates.
