靜電除塵器瓷柱用于靜電除塵器支撐懸掛電暈極懸掛框架，起支撐和高壓絕緣作用，瓷柱絕緣子適用于工作溫度不超過250℃、直流工作電壓72KV～120KV，安裝地點海拔高度不超過1000米的工作條件下使用。

瓷柱絕緣子嚴格按照GB/T772-2005《高壓絕緣子瓷件技術條件》和JB/T6746.3-93《電除塵器用瓷絕緣子》制造。絕緣子由瓷件和上下金屬附近用耐高溫膠合劑膠裝而成，瓷件端面與金屬附近膠裝接觸部分墊有耐高溫彈性襯墊，瓷件膠裝部位采用滾花，上砂等結構，防止松動，扭轉，以保證機械強度。瓷件表面施白色或棕色瓷釉，金屬表面涂高溫油漆。

注：不同瓷質等級的瓷件耐溫≤250℃、≤350℃、≤500℃、環境中使用，工作電壓為72-120KV,抗壓破壞負荷不低于300KN。

使用各種瓷瓶絕緣子產品時必須安裝平整受力均勻，運行設備前先給瓷瓶及安裝位置加熱烘干12-24小時左右（保證瓷瓶及安裝位置清潔干燥，不能有油污等潮濕現象，檢查電壓是否符合要求）才能運行設備），突然升溫降溫會導致溫差引起瓷瓶炸裂。

Electrostatic precipitator porcelain columns are used for electrostatic precipitator support and suspension of corona electrode suspension frames, serving as support and high-voltage insulation. Porcelain column insulators are suitable for use under operating conditions where the operating temperature does not exceed 250 ℃, the DC operating voltage is 72KV to 120KV, and the installation site is located at an altitude of not more than 1000m.

Porcelain post insulators are manufactured in strict accordance with GB/T772-2005 "Technical Conditions for High Voltage Insulators and Porcelain Insulators for Electrostatic Precipitators" (JB/T6746.3-93). Insulators are made of porcelain pieces and the vicinity of the upper and lower metal using high-temperature resistant adhesive. The contact part between the end face of the porcelain piece and the vicinity of the metal is padded with high-temperature resistant elastic pads. The bonding part of the porcelain piece adopts knurled, sanded, and other structures to prevent loosening and twisting to ensure mechanical strength. The surface of porcelain parts shall be painted with white or brown enamel, and the metal surface shall be painted with high-temperature paint.

Note: Porcelain parts of different porcelain grades have a temperature resistance of ≤ 250 ℃, ≤ 350 ℃, ≤ 500 ℃, and are used in the environment. The working voltage is 72-120KV, and the compressive damage load is not less than 300KN.

When using various porcelain insulator products, it is necessary to install them smoothly and evenly under uniform stress. Before operating the equipment, heat and dry the porcelain bottle and installation location for about 12-24 hours (ensure that the porcelain bottle and installation location are clean and dry, free of moisture such as oil stains, and check whether the voltage meets the requirements) before operating the equipment. Sudden temperature rise and drop can cause the porcelain bottle to explode due to temperature differences.
