metal oxide resistors main features:
metal oxide resistors is the core component of lightning arrester. Our company adopts the latest research formula materials and production process. The production of metal oxide resistors compared with domestic other products have 4 characteristics:
1)The flow capacity: 4/10μs large current impulse withstand, 2ms square-wave the flow capacity and line discharge rating index reached the domestic leading level.
2)Anti-ageing characteristic is excellent: Various types of resistors after in 115 °C, the 1000h corresponding chargeability aging test, aging coefficient Kct<1.0. ageing characteristic reached the domestic leading level.
3) Good protection features: Various types of resistors in the corresponding standards under the current shock residual pressure ratio reaches the leading domestic level.
4)Good homogeneity: Various types of resistors Reference Voltage at 1mA Dc and residual voltage parameters of uniformity index reached the leading domestic level
