The new device has a composite MOA with pillars function,surge arrester function,power function,examine the electrical gronding function of the four function together as a whole,has the form of a multi-purpose sturcture.Adopt this such devices can be reduced while a lightning cross arm;reduce sagging wire fixing three insulators;that is to reduce the sevenpeeling point,reduce construction wor,while reducing the six points of failure,it is able to simplify wiring devices,further increasing operational safety and reliability purpose,the line is more simple and beautiful.Furthermore,this device intergrates a variety of funcitonsthe need seven pointsof the original insulation stripping and insulation in one place,and the insulating cover design is reasonable,can truly full insulation,creating favorable condictions for the safe operation and charged.


The product characteristic:


1. Arrester core and jacket,by molding,making it non-dense whole cavity,eliminating moisture absorption caused by respiration,to prevent accidents caused by lightning chip damp fundamentally.

2. The surge arrester with a special internal reinforcement structure,it has a good mechanical function,can seve as insulators.

3. Arrester synthetic jacket with silicone rubber material to the anti-filthy strong performance and good proof performance,in additon,light weight,long life.

4. Arrester are III class heavy contamination by resistance design and production,and the insulation jacket minimum creepage distance of 31m/kv,creepage distance of 372mm.

5. Arrester overall structure optimized design,with a comvination of features.

  a.Both ground stms meet electrical inspection,the ground needs to simplify the tower unit.

  b.A special reinforcing structure,it has good mechanical properties,can doublepost insulators.

  c.The connection terminal blocks can be segmented cable fault,reduce the power range,with a knife breaking features.

  d.The arrester with full insulation design,can effectively prevent external damage and other accidents.


User Notice:


1. Before installation,the arresters shall be stored in clean and dry rooms and kept away form the corrosions by corrosive gas or liquid.

2. Before put into operation,preventative testing shall be made on the arrester.And after the arrester has been put into operation,regular testing shall be made as follows and follows and comparison shall be made with the data before the operation according to the attached table.(Every 5 years for arrester of 10kV or under,and every 2 year for arrester of 35kV and above)

a. Measure the insulation resistance of the arrester;

b. Measure the reference voltage of the arrester under direct current of 1mA

c. Meausre the leak age current under the reference voltage of 0.75 time direct current of 1mA


Used in:

1. Distribution networks
2. Transmission line
3. Substation
4. Railway power station
5. Alternator and electromotor
