靜電除塵器支撐石英管用于電暈極懸掛框架吊桿穿過場殼體處的密封和絕緣保護。根據產品的外形分為直形石英管和錐形石英管以及異型石英管。

嚴格按照GB/T772-2005《高壓絕緣子瓷件 技術條件》和B/T6746。3-1993《靜電除塵器用瓷絕緣子》制造。適用工作溫度小于800℃、直流工作電壓72KV～110KV，安裝地點海拔高度不超過1000米的工作條件下使用，表面無釉研磨，兩端面研磨。

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。

The quartz tube supported by the electrostatic precipitator is used for sealing and insulation protection at the point where the suspension rod of the corona electrode suspension frame passes through the field housing. According to the appearance of the product, it is divided into straight quartz tubes, tapered quartz tubes, and special-shaped quartz tubes.

Strictly comply with GB/T772-2005 Technical Conditions for High Voltage Insulator Porcelain Parts and B/T6746. Manufacture of Porcelain Insulators for Electrostatic Precipitators (3-1993). It is suitable for use under working conditions where the working temperature is less than 800 ℃, the DC working voltage is 72KV~110KV, and the altitude of the installation site does not exceed 1000m. The surface is unglazed and the two ends are ground.

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.
