for equipment can be up to 13.2 kV.Protects from Induced
OvervoltageNo maintenance is requiredNo special grounding
requiredThe outer air gap has been fixed before installation, and
the components have been pre-assembledProtection against: IOVOnly 1
product per pole is requiredProducts are installed with phase
alternation (А -> B -> C)Definitely great use and the highest
possible reliabilityLine Protection Device has been designed to
ensure the most effective protection from indirect strokes. This
device is able to perform as highly effective lightning protection
system, providing secure power network operation in 80% of such
issues.In order to protect sensitive equipment, such as
pole-mounted transformers (PMT), conventional metal oxide surge
arresters still must be usedOperational PrincipleEnsuring a high
ability to discharge excessive energy of an overvoltage in the
surrounding atmosphereThe induced overvoltage will create an
electrical power arc between the terminal electrode of a MLPD and
the conductor clamp on a line. First, the arc will be divided into
a series of small arcs by a series of discharge chambers, and then
quickly extinguished when the oscillating current of the grid
exceeds zero.Make full use of the grounding resistance between two
towers, each tower only needs to install one productIt is used for
the protection of overhead line induced lightning overvoltage,
which is more cost-effective than traditional
solutions.ParametersDescriptionUnitValueElectrical line
