Mar-Bal Glastic® 1872 Standoff Insulator, 3600 V, 3/8-16 x 9/16", 2-3/4" H, Red Catalog 

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
