They are supported by insulatorsevery 5 meters. The insulators are not made up of porcelain as in thiscountry, but are of hard rubber, moulded around an ironstud. So far this insulation has proved very satisfactory,being much less breakable than porcelain and seeming toretain its insulating properties. The use of these insulatorshas made it much easier to align the conductors, as theinsulators are not rigid. The contact device, or plow, differs radically from those.
