Molded Insulators have a higher resistance to heat and moisture when compared to regular plastic insulators. These molded insulators also have closer height tolerances and higher shatter resistance when compared to ceramic insulators. - Hi-Pot tested to assure electrical reliability. Wet or dirty conditions may require derating an insulator.
Features
- Glastic standoff insulators are molded of underwriters laboratories incorporated® (UL) recognized flame resistant fiberglass-reinforced thermoset polyester molding compound
- They feature shatter resistance and closer height tolerances than commonly available in porcelain insulators
- Moisture and heat-resistance properties of glastic insulators are higher than those of conventional plastic insulators
- Insulators mounted within a suitable electrical cabinet are considered indoors even though the cabinet itself is outdoors
- An insulator will withstand its rated voltage continuously but industry standards or other specifications may require a different spacing from conductor to ground for a particular voltage
Applications
- Glastic Insulators are Primarily Intended to be Used Indoors or Inside a Suitable Enclosure
