Surge Arresters MOV Metal Oxide Varistor For Semiconductor Component , IEC60099-4
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
