I. Product overview 
1.1  Overview
It can through training, let students be familiar with various electric accident reasons so as to prevent electric accident occur. Through learning, students will learn of how the accident occurs, and take cautions on electric accident, so as to enhance the ability of prevent accident, solve electric accidents. Students can learn many safety protection mode in the trainer.  

1.2 Feature
(1) Training workbench use aluminum column, testing measures, inner integrated training power box. It is easy to use, and it is not easy to be broken.
(2) Modular structure: it has many modules, and it can achieve many training projects, please see the experiment list later.
(3) It has good safety protection system, all the electric terminals select safety plug terminals, the whole set can be connected to ground, if there is electric leakage occurs, students can ct off power immediately, so as to protect themselves.
