Low voltage distribution cabinet

Low voltage distribution board designed by HEM is used to cut and distribute power to the main additional charge. The board is designed to be convenient for installation, repair and replacement. Board cover is made by 1.5-3mm sheet metal with electronicstatic power coating.

A low voltage distribution cabinet is a system that distributes the current from the place where the current flows into the smaller currents to ensure safe use as well as protection in case of device malfunction.

Low voltage distribution cabinet made of powder coated metal should be environmentally friendly, can be placed indoors or outdoors on the pole, and also low voltage distribution cabinet also works:

  • Electricity leak proof.
  • Anti-arc when device malfunction.
  • Fire and explosion protection.
