Description:
1, Arrester is a kind of overvoltage protector mainly applied for the protection of various electrical applicance in the power system.
2, The core elements of metal oxide arrester applies an advanced formulate with zinc oxide as the main material and has an outstanding nonlinear properties.
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.
