Electrician Experiment Box Educational Equipment Electrical Engineering Lab Equipment

1. Overview
Electrotechnics experiment box is mainly on "electrotechnics" and "circuit principle" high voltage electrical experiment, such as the single-phase AC circuit, three-phase circuit, the fluorescent lamp circuit experiment. This experiment case include module units and components library panel of combining form, are all made of European standard safety socket and the experiment of wire, wire is convenient, reliable contact, and long service life, high efficiency, effectively prevent electric shock hazard. Experiments on the front panel with element symbols and main parameters for the student identification. Visual in experiment box structure is compact and practical, safe and reliable, effectively raises student's beginning ability, easy maintenance and simple way. Can meet all kinds of high, electrician in a secondary schools and vocational technical college typical experiments.
