The SM series medium and low voltage insulators are expertly crafted in China, featuring cylindrical ends and a spindle-shaped middle section. These insulators are the most commonly assembled components in the traditional static electrical industry, making them essential for reliable performance, With a height range of 20 to 76 mm and a diameter of 17 to 50 mm, these insulators can handle operating voltages between 800 and 4000 V. One key performance indicator is the torque value, with installation torque varying from 3 to 30 N·m, depending on the specific size of the product, Manufactured from high-quality unsaturated resin materials, these insulators offer superior and stable insulation resistance. At a voltage of 1000 V, they demonstrate insulation resistance exceeding 23000 MΩ, ensuring consistent performance across diverse environmental conditions. As trusted suppliers and a reliable factory in the industry, we guarantee that our insulators meet the highest standards for durability and efficiency
