Surge Arresters 3EL
superior protection up to 550 kV
Light weight. Strong performance.
Answers for energy.
Simply irresistible.
By resisting wear in any environment.
Our high voltage surge arresters with silicone housing are
leading the way with superior design and construction. Built
with silicone directly molded onto the metal oxide (MO)
blocks, all arresters simply resist discharge and moisture
ingress under nearly all physical or environmental
conditions.
The surge arresters 3EL provide superior protection for system
voltages from 3.6 up to 550 kV. Combine these advantages
with a lightweight Cage Design™ and high robustness, and you
have outstandingly cost-effective solutions for station arresters,
line surge arresters or equipment protection. What do we
call these irresistible surge arresters? Simply 3EL. Another
outstanding product family from Siemens.
Good reasons for the 3EL
Our 3EL arresters use the same MO blocks as our 3EP and 3EQ
arrester product lines resulting in the same excellent electrical
performance. The innovative cage design using silicone and
fibreglass-reinforced plastic (FRP) rods as housing material leads
to a lot of additional advantages.
Cage design: high mechanical strength and
safe overload performance
The MO blocks of the 3EL are enclosed by a cage of prestressed
fibreglass-reinforced plastic (FRP) rods. The high tensile
strength of the FRP rods is used to hold together tightly the
arrester‘s MO blocks. The result is the 3EL family having one of
the highest mechanical strengths of polymer arresters available
on the market – in very low weight. In case of an overload or
a short circuit of the arrester – an extremely rare event – it is
impossible that any high pressure is built up because the MO
blocks are not enclosed in a sealed mechanical shell or wrapped
by any hard material. This permits the arc to escape directly
through the soft silicone housing and makes it hardly possible
that any internal parts could be ejected damaging other
equipment even if it is installed very close.
Long service life
Silicone is the only polymeric material that maintains its
hydrophobicity throughout its lifetime. Other polymeric
materials may be hydrophobic too, but lose their hydrophobicity
after a short period. Additionally, the silicone used for our 3EL
arresters is highly fire-retardant and self-extinguishing and is
2
not subject to erosion or UV radiation, which guarantees
long-term stability of the housing material (unlike other
polymeric materials like e.g. EPDM). The aging resistance of
our 3EL arresters has been proven by accelerated aging tests
(1000/5000 h salt fog test).
A long service life of 3EL arresters is also ensured by its cage
design: silicone is directly molded onto the MO blocks ensuring
total enclosure of all components free of bubbles and gaps
and thus making impossible any partial discharges or moisture
ingress.
Light weight – flexible and easy installation
The use of FRP and silicone as housing materials leads to a low
weight of our 3EL arresters, allowing easy transport and flexible
installation at all mounting angles (e.g. horizontal, vertical,
hung from the transmission line as line surge arrester). The
strength and weight of arrester supports can be reduced
as well as the need of heavy installation equipment. The sheds
of the 3EL are resistant to damage arising from transport,
installation, storms, earthquakes or vandalism.
Silicone: best performance under pollution
conditions
The silicone material used for our 3EL arresters is highly
hydrophobic – water and pollution do not form a continuous
conductive film on the surface. Thus surface currents and the
risk of flashover are reduced, especially in polluted or coastal
environments.
Superior material and design leading to an outstanding price-performance ratio …
… during operation
… during transport and installation
safe overload performance and high
mechanical strength due to cage design
light weight, easy and flexible installation
at all mounting angles
excellent electrical performance
resistance to damage arising from transport,
installation or vandalism
long-term stable hydrophobicity of silicone
housing ensures best performance even under
extreme environmental conditions (industrial/
polluted, coastal, desert)
extended creepage distance
… throughout the entire life cycle
long service life, no moisture ingress due to
direct molding of silicone onto MO blocks
highly fire-retardant and self-extinguishing

About IEC 60099-4
As a station arrester or line surge arrester for protection of
switchgear, transformers and other equipment in highvoltage systems up to Um = 550 kV against lightning and
switching overvoltages
For all arrester applications with high mechanical
requirements (up to 4 kNm, dynamic)
For erection at all mounting angles, e.g. hung from the
station structures, vertical installation, hung from the
transmission line (as line surge arrester)
For all applications where low weight and nonfragility of the
arrester are required
The IEC 60099-4 standard was extended in July 2006
by new rules for short-circuit tests of arresters. Whether
an arrester complies with the newly introduced
differentiation “Design A” or “Design B” depends on the
existence and size of the gas volume inside. While Design
A arresters are typically hollow (e.g. with porcelain or
composite housings), Design B arresters contain just a
small gas volume or none at all, so typically they are not
designed with pressure relief (e.g. „cage design“ or
„wrapped design“). Design B arresters are no longer
allowed to be tested with an internal fuse wire. Instead,
the so-called “pre-failing method” must be used before the
application of the high short-circuit current.
Our innovative “cage design” arresters – such as the 3EL2 –
are considered “Design B” according to the new standard.
Siemens was the first complete-range manufacturer
already fully in compliance with the new rules.
