Short deliveryperiods for fastavailability

Metal-enclosed 3ESsurge arresters fromSiemens.The 420-kVswitchgear in Maccles-field/Great Britain wasretrofitted with Siemenssurge arresters in a veryshort time.

Thus Siemens surge arresters can bespecifically and optimally tailored to thefollowing requirements and applications:

Excellent pollution layer characteristicsfor coastal and desert regions orin areas with extreme industrial airpollution

High mechanical stability, e.g. for use

in seismic zones

Extremely reliable pressure reliefbehavior for use in areas requiringspecial protection.

What is more, all Siemens surgearresters are sized for decades ofoperation in their design and materialused and provide a contribution to-wards the protection of the environment.

Well-suited even for themost arduous conditions

Medium-voltage arresters 3EK7

with silicone housing.

High qualityfor a long life

Even after 25 years,our 3EA1 low-voltagearresters are still op-

erating satisfactorily.

Surge Arrestersfrom Siemens Always the Best Solution

We offer an extensive range of surgearresters suitable for every application economical and ensuring stablecontinuous duty, with excellentprotection levels and loading capacity.

Developments in technology andpractical experience have resulted inthree different designs of surgearresters, which differ with regardto the housings used:

Surge arresters with porcelainhousings

Surge arresters with polymerhousings

Surge arresters with metalenclosures.

Siemens offers each of these threetypes of housing in various versionsand this enables us to provide theoptimum surge arrester for everyconceivable application.

With our comprehensive supply program,we are able to offer the right arrester forevery application for economical andreliable operation.

Our surge arresters protect transformers,generators, motors, capacitors, tractionvehicles, and cables as well as completeswitchgear.

Surge Arresters for Every Requirement

Arresters for special applicationsare possible, too. These include thefollowing:

For motors and dry-type transformersextremely sensitive to surges

Vibration-resistant surge arrestersand limiters for AC and DC tractionsystems

High short-circuit-proof versions forgenerators in power plants

Metal-enclosed versions for high-voltage gas-insulated switchgear

For thyristors in HVDC transmissionsystems

For capacitor batteries in staticcompensators

For airfield lighting systems

For electric furnaces in the glass andmetal industries

For test bays.

Surge arrestersfor the ICE

Arresters for specialapplications are our spe-ciality; they are ideallymatched to the respec-tive conditions of use,e.g. our 3EB1 surgearrester developed forthe ICE train.

Resistant to windand weather

Our 3EQ surge arresterswith polymeric com-posite housing areparticularly resistantagainst contaminationand all kinds of weatherconditions.

Our Product Range Is BeingContinually Extendedby Other Innovative Products

Our arresters and limiters cover all areasof application. What is more, we arecontinuously adding innovative productideas to our supply program to thebenefit of our customers.

An example of this are surge arresterswith polymeric composite housings.This housing consists of a glass fiber-reinforced plastic tube with a siliconrubber insulation. Thanks to its designand the high quality of the materials

used, this arrester offers a numberof advantages, such as absolutely reli-able pressure relief behavior and highmechanical strength even after pres-sure relief. Of particular advantage isthe water-repellent effect of the siliconrubber which is also transmitted to pol-lution layers.

Besides their high resistance in outdoorconditions, Siemens surge arresterswith polymeric housings also have along service life and can be disposed ofin an uncomplicated manner.

In Montagnais, Canada,Siemens erected threeadvanced series 3-phasestatic compensators pro-tected by arrester banks(consisting of parallel-connected multi-stackarresters) to improve thequality of power transmis-sion.These arresters evenwithstand extreme tem-

peratures of 50C to+40C.

Siemens High-Voltage Surge Arresterswith Polymeric Housing

5

Silicone is directly moulded onto MO-blocks and fibre-glass rods ensuringtotal enclosure of all components toprevent from partial discharges ormoisture ingress

good mechanical performance forstandard applications

Short circuit: Low-pressure escape ofthe arc due to the silicone shielding,no need of any pressure relief device

Easy transport and istallation due toconsiderably lower weight comparedto porcelain arresters

suitable as station arrester and/or trans-mission line-arrester

Design with FRP tube offers outstan-ding mechanical stability (much stron-ger than porcelain) combined with anexellent sealing system to prevent frommoistures ingress and partial discharges

Highest degree of safety in the eventof short circuit due to pressure reliefdevice, no ejection of any internal com-ponents

At least 75% mechanical strength re-tained even after short circuit, thereforearrester can be used as post insulator

less weight than comparable porcelainarresters

ideal for areas with potential seismicactivity, heavy windloads and any otheradvanced mechanical requirements

Siemens offers you two different arrestertypes with polymeric housing for stan-dard applications as well as for applica-tions with advanced or highest technicalrequirements: 3EL and 3EQ. Choosingone or the other, you will always get thebest price-performance ratio whateveryour application is.

Our 3EL and 3EQ arrester use the sameMO-blocks as our arresters with porce-lain housing resulting in the same excel-lent electrical performance. The use ofpolymeric housings consisting of FRPsand silicone rubber leads to additionaladvantages:

highly improved pollution---performance and

flexibility of erection due to reduced---weight.

Silicone rubber has been used as out-door insulation material for more than25 years with good service experienceeven under severe climatic and environ-mental conditions. Today it is the most

widely used polymeric material for HVoutdoor equipment.

Silicone is highly hydrophobic. There aremany polymeric materials with hydro-phobic properties, but most of themloose their hydrohpobicity after a rela-tively short period. Only Silicone has theability to maintain its hydrohpobicityduring its lifetime. This results in a longservice life of our 3EL and 3EQ arresters.

Additional important properties of silico-ne are:

-its resistance to tracking erosion and---UV-radiation that also enhances the---working life of our arresters and

-the fact, that silicone is fire retardant---and self-extinguishing.
