Surge Arresters 3ELsuperior protection up to 550 kVLight weight. Strong performance.

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 ac celerated 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.

Simply irresistible.

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

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.

By resisting wear in any environment.

Applications:

As a station arrester or line surge arrester for protection of switchgear, transformers and other equipment in high-voltage 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

About IEC 60099-4

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.

Control devices for surge arrestersThese control devices can be connected to all shown surge arresters in this catalogue.

Arrester condition indicator (ACI)

The arrester condition indicator shows the arrester status at a glance. Its easy-to-understand “traffic light” visualization is based on a 3rd-harmonic-evaluation of the leakage current.

Order Number: 3EX5070

Control spark gap

To estimate the current that flows through the surge arrester in case of an overvoltage and to count the surges.
