Sleeve Type, Class and Grade for AWG sized wire protection
Braided sleeving is a tubular product which can be produced from a variety of materials such as cotton, rayon, nylon, e-glass, s-glass and others; which is either impregnated, saturated or coated - or a combination of those processes, to enhance its electrical dielectric ratings.
Sleeving is categorized by the type of coating, base
fabric material, dielectric breakdown voltage, temperature index,
and inside diameter as follows:
Type 2
A flexible treated sleeving made from inorganic-base yarns such
as fibrous glass and impregnated or coated with an insulating
material which can be shown by applicable experience or
accepted test to have at temperature index of 130 (continuous
use at 130°C)
Type 3
A flexible treated sleeving made from inorganic-base yarns such
as fibrous glass and impregnated or coated with an insulating
material, such as polyvinyl chloride, which can be shown by
applicable experience or accepted test to have a temperature
index of 105 (continuous use at 105°C).
Type 4
A flexible treated sleeving made from inorganic-base yarns such
as fibrous glass and impregnated or coated with an insulating
material, such as silicone resin or polytetrafluoroethylene, which
can be shown by applicable experience or accepted test to have
a temperature index of 200 (continuous use at 200°C).
Type 5
A flexible treated sleeving made from inorganic-base yarns such as fibrous glass and impregnated or coated with
an insulating material, such as silicone elastomer, which can be shown by experience or accepted test to have a
temperature index of 200 (continuous use at 200°C).
Type 6
A flexible treated sleeving made from inorganic-base yarns such as fibrous glass and impregnated or coated with
an insulating material, such as epoxies, polyesters, or acrylics, which can be shown by experience or accepted
test to have a temperature index of 155 (continuous use at 155°C).
