Overview

It prevents faults such as leakage, creepage, short circuits, and flashover, and is a key component ensuring the safe, stable, and insulated operation of the electrostatic precipitator's high-voltage system, directly determining the equipment's uptime and dust removal efficiency.

Characteristics

Possesses ultra-high insulation withstand voltage performance and stable insulation strength, capable of withstanding long-term high-voltage operating conditions. Effectively isolates the high-voltage electric field from the equipment casing, preventing leakage, voltage run-through, and electric field attenuation problems, ensuring stable operation of the electric field at full load.

Made from high-purity industrial ceramics sintered at high temperature, it has a dense and uniform texture, high structural strength, and excellent compressive and bending resistance. It can withstand the equipment's own weight and vibration, is not easily cracked or broken, and is suitable for long-term continuous industrial operation.

The product surface features a smooth glaze treatment, providing moisture resistance, condensation prevention, and dust accumulation prevention. It effectively resists the adhesion of wet flue gas and dust, significantly reducing the probability of surface creepage and flashover failures, making it suitable for various complex flue gas conditions in both dry and wet electrostatic precipitators.

It exhibits excellent high-temperature resistance, aging resistance, and corrosion resistance, allowing it to withstand long-term exposure to high-temperature flue gas and trace amounts of acid and alkali corrosion. The material properties do not degrade or deform, resulting in a long service life, making it suitable for harsh conditions in power plants, metallurgy, and chemical industries.

The standard installation structure design ensures precise assembly and positioning, a high degree of fit, and stable installation, preventing loosening. Disassembly and maintenance are convenient, and the overall operational failure rate is extremely low, guaranteeing long-term stable operation of the electrostatic precipitator system.

Suitable Applications

Widely compatible with dry electrostatic precipitators, wet electrostatic precipitators, and high-voltage insulation systems of high-voltage electrostatic precipitators. Primarily used in electrostatic precipitators operating in high-temperature, high-humidity, and corrosive flue gas environments such as thermal power generation, heating, metallurgical sintering, cement kiln tail, chemical waste gas, waste incineration, and biomass combustion, these are essential insulating components for high-voltage electrostatic precipitators.

Maintenance Design

The product is shipped as a one-piece molded standard part with an intact glaze, free of pores and cracks, meeting insulation performance standards and offering strong component versatility. It features a dedicated sealing, dustproof, and anti-condensation sheath structure, effectively protecting the ceramic surface and preventing insulation degradation caused by dust accumulation and condensation. Customization of multiple voltage ratings and sizes is supported, allowing for matching models based on the equipment's high-voltage level, operating temperature and humidity, and installation structure. It is compatible with both new and old dry and wet electrostatic precipitators for installation and replacement.

Note

Porcelain insulation is a core safety component for electrostatic precipitators. Dust accumulation, condensation, cracking, and glaze damage can all lead to insulation failure and electric field tripping. Regular cleaning and inspection of the appearance are necessary, along with timely replacement of aged and damaged components to ensure stable operation of the high-voltage electric field.
