• Medium-voltage distribution networks

3EK8 silicone rubber surge arresters-Medium Voltage Surge Arresters For Distribution Networks

Siemens 3EK8 silicone rubber surge arresters with wrap design effectively protect medium-voltage distribution networks from overvoltage.

Siemens 3EK8 wrap design surge arresters are ideally suited to provide reliable protection for:

• Transformers
• Circuit breakers
• Medium-voltage switchgear
• Medium-voltage distribution networks

ARC Protection System- Medium Voltage Surge Arresters for Distribution Network

If excess voltage exceeds the energy absorption capacity of a surge arrester, the metal oxide blocks can be damaged and cause the surge arrester to fail. This causes fault current, and an arc forms at both end fittings of the surge arrester. Melted metal can fall to the ground and cause a fire.

This is why type 3EK medium-voltage arresters for distribution networks can be equipped with an Arc Protection System (APS), which is installed at both ends of the surge arrester. The APS consists of electrodes nested within each other, which create the power to rotate the arc around the surge arrester housing. This reduces the formation of molten material at the end fittings, dramatically decreasing the risk of forest fires.
