HTG - THERMAL CLASS 240

HEAT TREATED 
FIBERGLASS SLEEVING
648°C Operating Temperature
DESCRIPTION:

WEICO's HTG is a braided fiberglass sleeving which has been heat treated
to remove all organic matter and render it fray resistant. It provides maximum
abrasion resistance with high flexibility. HTG sleeving is universally used as
primary insulation in low voltage applications, particularly where high temperatures
are encountered. It is also widely used as supplementary insulation and protection
for other types of primary insulation. HTG is used wherever severe repeated flexing
or temperature extremes prohibit the use of other materials. Typical applications include:
insulation of carbon brush leads in electric motors; transformers and ballasts for halogen
lighting fixtures; outer coverings for hydraulic lines; thermal or electrical insulation for
onsumer, commercial or industrial appliances; double insulation for high reliability circuitry.
This same sleeving can also be supplied with a light impregnant which further minimizes
fraying and helps maintain a round cross section where this is desirable. The impregnated
type is also available in colors. Both types are easily expanded for ease of installation.

CHARACTERISTICS:
HTG sleeving has an operating temperature of -60°C to +648°C.
Saturated (impregnated) maintains its integrity through the same temperature range,
but colors may begin to fade at +205°C
