Applications:

?

1. Small in size,light in weight,durable in collision,clash and break age free in transportation,easy in installation,suitable for application in the switchboard.

2. Special structure,integrated extruding shaping,without air gap,good sealing performance,damp prevention and explosion prevention.

3. Long creepage distance,good hydrophobicity performance,strong pollution resistance abilities,and stable performance,reducible in operating maintenance.

4. Zinc oxide resistor disc in special formula,small leak age current,slow aging speed,long service life.

5. The actual DC reference voltage,square wave discharge capacity and heavy current tolerance value are all higher than the state standards.
