6. Insulators and insulating substrates
Their function is to insulate live conductors from masses which generally act as supports (e.g. metal frameworks). Their characteristics depend in particular on :
of the nominal mains voltage ;
station short-circuit current ;
the mechanical characteristics required;
the severity of site pollution.
they comply with standards IEC 60071, NF EN 60071, NF EN 60507 and IEC 60815.

Their mechanical characteristics are described in standard NF EN 60305. Readers are...
