The working principle of the Insulated Piercing Clamp
is to insert the branch cable into the branch cap and determine the position of the main thread when connecting to the cable branch, and tighten the torque nut on the thread clip with the sleeve wrench. The hidden insulation of the puncture blade is gradually closed. At the same time, the arc sealing rubber pad wrapped around the puncture blade gradually close to the cable insulation layer.
When the sealing degree of sealing pads and insulating oil and the contact with the metal body with the metal body, the torque nuts are automatically falling off. At this time, the installation is completed and the contact point sealing and electrical effects have reached the best.
