Force according to the condition by yourself
5) appropriate flexibility and rigidity, great power
6) we can drill through hard objects such as wooden, plastic and cement and
Push them out
Features:
1) this device can reach perfect effect to electromotor for oil field and clothing.
This device can be applied to all kinds of three-phase electrical equipment
Especially some complicated equipment with heavy load
2) usage: try to install it in front of electrical equipment and at the back of
Ammeter. As all the engineering products have been installed in the box, it is
Very convenient to install. After installing, all the indicator lights turned
Bright, the device begins to effect on electricity-saving
3) work load: each j.S.D three-phase electronic power saving engineering
Contains six sets of three-phase electronic electricity saving devices. Its work
Load is 60kw, 380v, 50-60hz, three-phase
4) life span: six to eight years
5) remark: the effect is distinct after a month, the longer time you use it, the
