FIELD: electricity. ^ SUBSTANCE: insulator includes end terminal having the possibility of being connected to load-carrying design; end terminal has the possibility of being connected to wire, and earthing insert provided with possibility of being earthed, as well as insulation elements mechanically attaching each of end terminals to earthing insert. Earthing insert is located essentially at equal distances from end terminals or located closer to one of end terminals. Earthing lead-out is attached to earthing insert in non-detachable or detachable way. ^ EFFECT: absence of electric current flow via load-carrying design if leakage currents are available in insulator or in case of appearance of electric arc. ^ 8 cl, 1 dwg |
