Metal Oxide Varistor By Cedicom Electronics

We are eminent manufacturer and supplier of Metal Oxide Varistor in Shoranur, Kerala, India. We manufacture a wide range of Metal Oxide Varistors (MOV'S) for Surge Protection Application. The AC power line environment contains electrical high voltage transients/surges due to lighting, line to ground faults, short circuits fuse blow, switching on and off heavy electrical machinery and many more causes. These voltage surges could be high as 6KV and can last for a few micro seconds to milliseconds, further more, the frequency of these surges often could be at least four times a day. These transients, inspite of their normally short duration, are extremely damaging to the modern electronic equipments where in advanced IC's and other components are used and are very sensitive to such high voltage surges. Major failure in these sophisticated electronic systems are attributed to these transients. Besides failure in electronic systems these transients can also cause damage to electrical systems by damaging transformers, contractors and similar components by causing insulation break-down, spark over, etc.

To overcome the problems associated with the transients, often surge suppressor devices are used. Amongst the suppressor devices that are available "Metal Oxide Varistor' (MOV's) are the latest type of electronic devices used for surge suppression.
