【Function
and Purpose】
Without
excavation, Shengli SL-206B cable failure locator is able to find out the
running direction, buried depth and failure points of underground
communications and electricity cables in a convenient and accurate way, so it is
the indispensable equipment and a quite helpful assistant for electricity,
communications and industrial enterprises.

【Detecting
Principles and Methodology】
By
sending a specified electrical signal to underground cables, the cable failure
locator determines the running direction and the depth of buried cables based
on the principle that the received signal is the smallest (almost zero) when
the probe is vertically tangent to the magnetic horizon.
