Each extension has orifices formed perpendicular to side walls thereof. Inserted in orifices are bolts for fixing inserts. One insert of dielectric material, preferably wood, is located central channel. Another one is arranged between ribs of two segments and also made of dielectric material, preferably wood. Above insert has length exceeding segment length, height, which is 1.25 - 2.5 times greater than rib height and width increasing distance between rib surfaces facing each other. Insert has projection parts extending the full length thereof and having chamfers and side ledges located in chamfer areas cooperating with edges of above ribs.
