What Is an Insulated Torque Wrench?
Insulated torque wrenches, made from non-conductive materials, are used for the maintenance and inspection of electrical facilities and equipment. Being non-conductive, they prevent electric shock and are suitable for high-voltage operations due to their high dielectric strength.
These wrenches come in two main types: preset and drag. Preset wrenches allow tightening to a pre-set torque level, enhancing work efficiency, while drag wrenches automatically release torque when the set value is reached to prevent over-tightening.
When selecting an insulated torque wrench, it is important to consider the application, the required torque range, and dielectric strength to ensure safety and reliability during use.
