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.

Note :

they comply with standards IEC 60071, NF EN 60071, NF EN 60507 and IEC 60815.

6.1 Insulating chains

Note :

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