SM Series Insulator

The SM series medium - and low - voltage insulators are designed with cylindrical ends and a spindle - shaped middle section. They are also the most commonly assembled insulators in the traditional static electrical industry.

Their height ranges from 20 to 76 mm, the diameter ranges from 17 to 50 mm, and the operating voltage is approximately between 800 and 4000 V.

In terms of performance, the main parameter to be considered is the torque value. Depending on the size of the product, the installation torque ranges from 3 to 30 N·m.

Since they are made of unsaturated resin materials, they have relatively high and stable insulation resistance values. At a voltage of 1000 V, the insulation resistance is greater than 23000 MΩ, enabling them to maintain stable insulation performance under different environmental conditions.
