5 Features

5.1 The accuracy and quality of the switchgear could be ensured as the framework parts and special parts supplied by us. Modular design of the dimensions concerning (E=20mm), which has cut production time and enhanced efficiency.

5.2 The heat dispensation channel at the top and bottom of the switchgear formulate a ventilation loop to dispens the heat.

5.3 Easy for installation and dismantling.

5.4 The switchgear is with perfect earthling protection system.

5.5 The cover of the switchgear could be removed for installation and adjustment of the main bus bar. There are also rings for lifting and delivery of the switchgear.

5.6 The protection degree is IP30. As per your requirements, switchgears with protection degree of IP20IP40 are available.

5.7 Flexible circuit plans are available.
