6kV ~ 81.5kV  

 

FEATURES

 

http://www.sew.com.tw/images/d.gif Telescopic, compact, light-weight.

http://www.sew.com.tw/images/d.gif Light weight easy to sue and handy.

http://www.sew.com.tw/images/d.gif High-voltage detectable. The equipment, whether in stretched state is available for voltage detection in high-tension.

http://www.sew.com.tw/images/d.gif Easy to recognize indication. Intermittent lighting in red of a high intensity light emitting diode and intermittent audible sound of an electronic buzzer are easy recognizable at a full daylight, noisy location.

http://www.sew.com.tw/images/d.gif Water proof. The detecting head, being tightly enclosed, is free from any trouble due to dust, water.

http://www.sew.com.tw/images/d.gif IEC/EN 61243-1, 60068-2-6, 60068-2-32, 60068-2-14

 

http://www.sew.com.tw/images/d.gif The detector detects high and extra high voltage in AC lines. An elongate insulation rod permits checking of high tension circuits at a safe distance for voltage. Also it is telescopic compact, light-weight, easy to sue and handy.
