R-525 Electric Insulators

[R-525]

Electric insulators for various applications: bus bars, switch gear, etc. Insulators are made with a glass reinforced polyester bulk molding compound, and aluminum threads. They are compression molded to give you the highest strength available.

The BMC (Bulk Molding Compound) material is U.L. listed 94-VO for flammability, and meets requirements for the U.L. 891 standard for safety. Every insulator is hi-pot tested at 3,000 volts, and inspected for: cracks, short spots, and defects of any kind

Applications

Custom sizes and shapes available
Available with aluminum, brass, or steel inserts

Available with female or male inserts upon request
