Station and Intermediate Class Surge Arresters

Station and Intermediate Class Surge Arresters Product Overview siemens.com/energy/arrester Answers for energy.

High Voltage Reliable Protection Siemens surge arresters have successfully defied high winds, severe weather, harsh environments and even earthquakes for decades. Our surge arresters exhibit the properties and provide the benefits that ensure they will perform as intended protecting equipment and systems from lightning and switching overvoltages. With decades of experience in the design and manu facturing of high voltage power supply components, Siemens also specializes in advanced Silicone Rubber (SR) insulated surge arresters providing the highest levels of mechanical strength, performance and safety even in the most demanding environments, such as in contaminated, industrially polluted, high seismic and vandal prone critical installations. The product family of our surge arresters offers the right solution to any specific need. They have a proven fit for protecting transmission lines and transformers, as well as complete switchgear from the hazards of high voltage start-up surges, line transients and lightning. Siemens surge arresters have been successfully tested to the latest ANSI/IEEE Standard C62.11. As pioneers in the field of Silicone Rubber (SR) insulation and one of the few suppliers with comprehensive inhouse research and development capabilities in this industry, we can also provide surge arresters customized to very special requirements. The cost-effectiveness of our products is underscored by uncompromising quality ensuring the long service life and reliability of each application. Available off-the-shelf, the 3EL standard series of our SR surge arresters have been designed to meet the requirements of a wide range of common installation environments. For more demanding applications, our high-end 3EQ series will maintain at least 75 % of its nominal mechanical strength in the event of a pressure relief, and can thus also be used as a regular support (station post) insulator. 2

Siemens Promise System Reliability Silicone Rubber (SR) Insulation for Safety Siemens offers two different types of arresters with SR housing: The 3EL series for standard applications, and the advanced 3EQ series for the highest performance needs. Both are designed using the same glass collared MOV-blocks resulting in outstanding electrical performance. SR has been used as an outdoor insulation material for over 25 years, with excellent service experience even under severe climatic and environmental conditions. Today, it is among the most widely used materials for HV outdoor equipment. Silicone is highly hydrophobic. While there are many polymeric materials with similar initial hydrophobic properties, most of them lose their hydrophobicity after a relatively short period such as EPDM based alloy rubber. Only the true SR is capable of maintaining its hydrophobicity throughout its entire lifetime. This ensures the long service life of our 3EL and 3EQ arresters. Further key advantages of SR especially compared to EPDM based alloy rubber include: High resistance to tracking erosion Excellent resistance to flashover Superior UV stability Self-extinguishing flame retardancy Adaptability to variable design and ease of processing For additional information call for our publication on Silicone Rubber insulation. 3

One Goal 3 Designs 3EL Silicone Rubber (SR) Surge Arresters with Cage Design 3EQ Silicone Rubber (SR) Surge Arresters with Tube Design 3EP Porcelain Surge Arresters The standard 3EL series is based on a cage of prestressed fiber glass reinforced rods for high mechanical strength. The SR insulation is molded directly onto the MOV-Blocks. The design provides an optimum price/performance ratio for applications up to 345 kv system voltage. The 3EL1 series as lower voltage station class surge arrester is an enhancement of our 3EL product line. 3EL The fiber reinforced plastic (FRP) tube material has been chosen to provide the highest possible mechanical strength. Due to its excellent pro cessibility, the SR insulation is molded directly onto the FRP tube. The 3EQ tube design is considered the best choice for applications up to 1200 kv system voltage, particularly in locations or installations with demanding environmental or extremely high mechanical/ seismic requirements. 3EQ The high-quality porcelain housing of the 3EP as well as the special grade sulfur cement bonding of housing and flanges en sure outstanding mechanical strength, for applications up to 800 kv. 3EP Total encapsulation of all components to avoid partial discharges and moisture ingress High mechanical performance for standard applications Silicone Rubber shielding provides low-pressure release of the arc in the event of a short circuit Significant weight savings vs. comparable porcelain arresters, facilitating transport and installation of the arresters Suitable for use as substation and/or line surge arresters FRP tube design for outstanding mechanical stability (much stronger than porcelain), combined with an excellent sealing system for long-life protection against ingress of moisture and partial discharges Highest level of safety in the event of short circuits, no ejection of any internal components Retention of at least 75 % of initial mechanical strength even after short circuit, permits the use of the arrester as a support insulator Weight savings vs. comparable porcelain arresters Ideal for applications in areas exposed to high seismic activity, heavy wind loads and any other demanding mechanical requirements Available as single-unit arrester rated up to 300 kv or two-unit arresters for up to 550 kv, minimizing the required number of units High reliability over a wide range of temperatures and extreme temperature changes from 67 F to + 122 F ( 55 C to + 50 C) Reliable technology with a proven history Optimized glass collared MOV-block design Pressure relief system for very fast venting, providing the highest possible means of safety in areas requiring special protection Very high cantilever strength Highly reliable sealing system and state of the art seal test set-up make Siemens arresters completely reliable 4
