Szczegółowy opis produktu

 Silicon Carbide Varistor / Block Varistor MOV 6.8KV For Surge Arresters

 


Quick Detail:

 

1.Good non-liner speciality
2.No redundant current
3.Large galvanization
4.Smart response

5.Low clamping voltage , good protection performance
 
 
Description:
 
Metal Oxide Varistor is a ceramic semiconductor component made of zinc oxide as the main material.Its resistance value varies with applied voltage and it is the core components of metal oxide arrester.Its quality directly determines the performance of surge arrester.Our company's metal oxide varistor is characterized by strong galvanization capacity,high protective performance,good nonlinear characteristic,fine appearance,varisos specifications and so on.The common voltage gradient range is 200~230V/mm.Its diameter and height can be determined neatly according to the customer's requirements.The varistor's maximum diameter can reach 138mm and the maximum height can reach 41mm.
 
 
Applications:

 

1.Components for surge arresters in electrical system

2.Absorbing surge of the switch tank and over voltage protection

3.Absorbing surge of the energy and over voltage protection

4.Electrical railway surge protection
