Simply irresistible Resists 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 3EL surge arresters provide superior protection for system voltages from 3.6 up to 550 kV. Combine these advantages with a low weight 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 fiberglass-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 fiberglass-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 almost impossible 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 also be hydrophobic, too, but lose their hydrophobicity after a short period. Additionally, the silicone used for our 3EL arresters is highly fire-retardant and selfextinguishing and is

not subject to erosion or UV radiation, which guarantees long-term stability of the housing material (unlike other polymeric materials such as EPDM, for example). 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.
Low 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.

Applications: 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.
