GDJW-40B Wireless Live Insulator Distributed Voltage Tester
I. General information
GDJW-40B wireless insulator tester is used for testing distributed voltage of live suspended insulators and suspended insulators in the laboratory. It can effectively find hidden faults inside the insulators, improve the reliability of power grid system operation, and improve the working efficiency of line staff in carrying out live testing.
This product adopts wireless transmission technology. The communication distance between detector and hand-held terminal can reach over 100m, making the measurement process safe, reliable, fast and accurate. In addition, its strong anti-interference ability fully meets the EMC standard, suitable for various electromagnetic interference occasions.
II. Features
With multiple mode, more applicable, more safe and convenient;
Universal joint design, measurement direction can be adjusted flexibly according to the hanging position of insulator string;
Double-shielding, strong anti-interference ability fully meets EMC standard;
Unique man-machine interface, simple to operate.
