◆It is highly reliable even under long-term high temperature of 200℃ and high pressure of 140MPa

◆The insulator can be used for a long time in high temperature and strong acid medium (H2S, SO2) underground without being corroded

◆It has unique comprehensive properties, with wear resistance, chemical corrosion resistance, mechanical strength, and stable electrical properties throughout its entire operating temperature range, which helps to maintain the integrity of the collected data while causing lower electrical interference.
