Anode earth type electrodes EFS

Physical form

Electrode of efs-b type is a cylindric casting of corrosion-resistant iron-silicon alloy (ferrosilyd) with multiwire copper cable attached to the contact unit.

Electrode of efs-v type is a metal casing in which the casting of corrosion-resistant iron-silicon alloy (ferrosilyd) is placed in activator mixture with multiwire copper cable attached to the contact unit.

Electrode of efs-g type is a cross-type casting of corrosion-resistant iron-silicon alloy (ferrosilyd) with multiwire copper cable attached to the contact unit.
