Product Details

LAZBJ-10 high/medium-voltage wall bushing is a current measurement and protection device specially designed for use in power systems, especially in high-voltage and medium-voltage environments. It uses advanced manufacturing technology and high-quality insulating materials, such as epoxy resin, to ensure stable and reliable operation under high voltage and high current conditions. It is usually installed in the wall-penetrating position of power equipment to transfer high current from the primary side to the secondary side for use by measuring instruments and protection devices.
