Low voltage circuit power transformer LST lightning-resistant transformer

Low voltage circuit power transformer LST lightning-resistant transformer

The key to lightning surge protection!! An excellent surge suppression mechanism quickly guards electronic devices.

This trans system is equipped with arresters (lightning protectors) in its primary (input) and secondary (output) circuits. The arrester effectively acts against induced lightning surges or internal lightning phenomena; however, it may not be able to protect the equipment being safeguarded if it encounters impulses beyond its performance or direct lightning surges. The main component of this system, the power transformer, uses high-quality insulating materials at key points to function safely against lightning surges and has an extremely high insulation resistance.
