High Voltage Insulator
An electrical insulator is a material that impedes
the free flow of electrons. Insulators of different classes and
materials are used as mechanical supports for transmission and
distribution lines, as well as substation lines. Due to their
resistivity, these insulators also are installed to prevent line damage
from arcing.
Products include:
- Insulators or
insulating parts of wet-process porcelain or toughened glass, or
non-ceramic composites, whether or not assembled with metal parts, used
in the transmission or distribution of electrical energy or for use as a
part of a large electrical machine or piece of equipment; and
- Clamps, fittings, and accessory hardware used directly with such insulators or insulating parts that affect their functioning.
