Overvoltage Protection Distribution Surge Arrester Unique Polymeric
1, Overvoltage Protector
Overvoltage protector of universal and combined type(TBP),which
points at the characteristics of
overvoltage in power system at present,and draws experiences from
the operating of more than 10 types of overvoltage protectors, is a
new style with unique structure connection mode and available new
2, Competitive Advantages
Compared with others (various combined overvoltage protectors
including), there’re incomparable advantages that superior
performance and reasonable parameters.Due to the ferfect
functions,the protector imposes reliable and effective restrictions
to overvoltages,such as atmosphere, switching, interphase and the
overvoltage relative to the ground.And it’s available in accurate
action and split-phase count. For the large current capacity,it’s
more suitable for the places with higher requiements for the
restricted effect of the overvoltage.The accidents of thermal
breakdown, initiated by the cause that the capacity of overvoltage
exceeds protector,will be avoided.
The protector,what has been widely used in industries such as
power,metallurgy,chemical,coal,and light industry,is an ideal
equipment to protect the insulation of electrical equipments as
motors,generators, transformers, switchs, generatrices, capacitors,
cables, and arc furnaces.
3, Main Specifications and Technical Parameters
Overvoltage protector for motors,generators, transformers, switchs,
generatrices, and parallel
of the object
voltage of switching impulse
1.2/50 impulse discharge voltage & residual voltage
Residual voltage of lightning impulse (crest)
|Inter phase distance|
It is an advanced protection appliance that the overvoltage
protector restricts the lightning voltage and the switching voltage
,and protects the interphase overvoltage and the overvoltage
between the phase and the ground.It’s mainly applied to protect
electrical equipments from damages,such as generators,
transformers, vacuum switchs,generatrices, and motors.
