Description:
Disc insulators are also called suspension insulators. They are actually a piece of ceramic or glass with steel caps and iron feet at the upper and lower ends, which can be used in series.
Suspended insulators are generally made of insulating parts (such as porcelain and glass) and metal accessories (such as steel feet, iron caps, flanges, etc.) glued or mechanically clamped with glue. Insulators are widely used in power systems, generally belong to external insulation, and work under atmospheric conditions. Overhead transmission lines, busbars of power plants and substations, and external live conductors of various electrical equipment must be supported by insulators and insulated from the ground (or ground) or other conductors with potential differences.
Usage:
As one of the important equipment of transmission lines, suspension insulators are responsible for the suspension of conductors and the insulation of iron towers. The suspension porcelain insulators produced are used on high-voltage, extra-high voltage and ultra-high voltage transmission lines around the world, and are used for transmission lines in various countries Safe operation provides reliable version guarantee.
Suspended porcelain insulators are divided into two types: insulators for AC systems and porcelain insulators for DC systems.
