ELECTROSTATIC PRECIPITATORS INSULATORS (ESP INSULATORS)
ESPI Europe is a global specialist in designing, manufacturing, and distributing insulators for electrostatic precipitators (ESP insulators).
Our portfolio consists of of support insulators, wall bushing insulators, shaft (rotary) insulators, solid-core post insulators, suspension insulators, rapping rods, stabilizers, anti-sway bars or dumping insulators.
ESP SUPPORT INSULATORS
The purpose of the ESP support insulator is to support collecting plates, which are high-voltage positively charged electrodes, and to insulate them from the electrostatic precipitator housing. Support insulators can possess a cylindrical or conical shape and are crafted from ceramics that are resistant to high pressure and temperature.
ESP WALL BUSHING INSULATORS
The function of a wall bushing is to permit an electrical conductor to pass through a wall from the outside to the chamber. Bushing insulators can have a smooth surface body or various shapes depending on the required creepage distance.
ESP SHAFT INSULATORS
The role of the shaft insulator within the ESP is to facilitate the rotation of the rod. This rod, in turn, initiates the movement of hammers that gently tap the collecting electrodes within the electrostatic precipitator. This tapping action serves to dislodge dust from the electrodes, effectively cleaning them.
ESP DAMPING RESISTANCE INSULATORS
Damping resistance insulators play a crucial role in absorbing the higher harmonic components present in the secondary circuit of the rectifier transformer. This absorption helps prevent resonance within the output circuit, subsequently safeguarding the rectifier transformer. To achieve this protection, damping resistors should be installed at the output terminal of the rectifier transformer.
ESP HIGH ALUMINA INSULATORS
High alumina insulators are crafted from materials containing a substantial 95% proportion of Al2O3. These insulators are particularly well-suited for use in electrostatic filters operating at elevated temperatures, reaching up to 500 degrees Celsius. They exhibit an enhanced capacity to endure thermal shocks and boast remarkable mechanical strength. Typically, their surface remains unglazed.
Using high alumina material, a diverse range of insulators can be manufactured, including support insulators, wall bushings, shaft insulators, rapping rods, stabilizers, and anti-sway bars.
