Catalog Number Key
The Quadri*Sil® Insulators Numbering Scheme is organized according to a smart numbering system. Each group of digits de-
fines a characteristic of the product you are ordering. To fill out this form, start on “a: Insulator Type.” Then, fill in your selection
in the box corresponding to the letter “a.” Apply the same rule for all the other sections.
a d
e
c
b
a) Insulator type. Defines your insulator type: Post or
Suspension. Select “P” or “S” for Post or Suspension,
respectively, and fill in your selection in the box designated
for “a.” In this example, we selected a suspension insulator.
d) Weathershed Profile. Defines the leakage distance
design. For a suspension insulator with standard leakage
distance, use “S.” For a suspension insulator with high
leakage distance, use “H.” For a line post, only the
standard leakage distance design is available. Fill in your
selection in the box designated for “d.” For example, if you
want an insulator with high leakage distance, you would
place an “H” in the box designated “d.”
e) Top Fitting. Defines the top end fitting of your insulator.
Fill in your selection in the box designated for “e.” For
example, if you want a suspension insulator with a
Y-clevis top end fitting, you would place a “2” in the box
designated for “e.”
3 digits for distance between metal parts, in inches
c) Polymer length. Defines the polymer length of the
insulator (please use catalog tables for possible polymer
lengths). Fill in your selection in the boxes designated for
section “c.” For example, if you want a 49-inch polymer
length, enter:
b) Strength. Defines the mechanical strength of your
insulator. Fill in your selection in the boxes designated for
“b.”
Note: kip = Kilopound, kN = Kilonewton
For example, if you want a Suspension insulator with 25 kip,
this is what your form would look like so far:
