4 Polymeric
Housed MOA of Pole Type
This product can be used to overvoltage protection.of equipments
and not only has protection fuction, but also can be used for pole
insulator. It can simplify the installation of transformer and cable
, reduce components of telegraph pole and save cost. Technical datum
meet with national standard JB/T8952-1999 and GB11032-2000. The
technical parameters are given in Tab 3.

5 Polymeric
Housed MOA with Disconnect Device
This product can be used to overvoltage protection, especially
in neutral-point unearthing system. After long period operation
or under long time overvoltage because of single-phase earthing,
varistors will quickly deteriorate. Then Disconnect device will
act and MOA will exit operation. After they come away, they have
obvious sign and it benefits to maintain conveniently.
Technical datum meet with national standard JB/T8952-1999 and GB11032-2000.
The technical parameters are given in Tab 4.
