Current-Graded Live Indication Device
Product Name: Current-Graded Live Indication Device
Product Model: TLKS-PDI
Product Remarks: Recommended New Product - Anti-External Damage Live Warning Device
for Three-Span Lines
Product Category: Anti-External Force Warning Series
1. Product Overview
The Current-Graded Live Indication Device adopts an equipotential design, featuring high-
voltage insulation and
anti-electromagnetic interference. With a small size, light weight, and high-brightness
LEDs, it is suitable for
hanging installation and operation on high-voltage grade overhead lines of power grids. It
works independently at
the same potential as the high-voltage lines, with no impact on the normal operation of the
lines.

The device is fully sealed and filled with insulating epoxy resin, which seals the main control
board and all
components. Its fully enclosed design ensures high pressure resistance, strong anti-
interference capability, and
stable and reliable operation.

This product is a prompt safety device that is directly hung and installed on high-voltage
overhead lines to
indicate whether the lines carry operating current. When the high-voltage conductors
carry operating current,
the device's LED lights flash to warn that the high-voltage lines are in live operation. It also
has a graded display
function: the greater the current on the line, the brighter the LED display intensity. The
product can play a role in
live safety warning, and at the same time, the approximate current magnitude on the line
can be judged based on
the number of illuminated LEDs.
