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 p
­ erform as intended –
­protecting equipment and systems from
­lightning and switching overvoltages.
With decades of experience in the design and manu­facturing 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.
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 u
­ sing 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.
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.
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.

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 p
­ restressed
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.
The fiber reinforced plastic
(FRP) tube material has been
chosen to provide the highest
possible mechanical strength.
Due to its excellent pro­cessi­
bility, 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.
The high-quality porcelain
housing of the 3EP as well
as the special grade sulfur
­cement bonding of housing
and flanges en­sure
­outstanding mechanical
strength, for applications
up to 800 kV.
3EL
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
■■

3EQ
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)
■■
3EP
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
■■
Product Range
We offer multiple models for each family of arresters.
They differ mainly in diameter and length of the
housings and size of the M
­ OV-blocks to fulfill different
customer ­requirements.
