 6.7KV Block Metal Oxide Varistor MOV For Surge Arresters , ZNR Varistor

Quick Detail:


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

5.Low clamping voltage , good protection performance
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.
