this case
the earth contact the foundation earther no
longer intact.
• Further studded strips the exterior walls produce
a very strong electrical insulating effect.
Studded plastic strips
• Made special, high-density polyethylene.Example: studded plastic strips
Influence plastic films the earthing resistance
Generally there negative influence between the
strip foundation foundation plate and the earth in
this area.
"Simple" films:
• With simple films, the foundation earther effect is
limited. the in-
dividual membranes overlap, the earth contact of
the foundation earther impaired. The foundation earther effective an
earther the strip foundation the foundation
plate.
• However, earthing resistance usually still suffi-
cient.
Because the foundation earther longer has contact
with the earth here, additional grid ring earther
must created.
