 |
Detector insulator has one or several ceramic capacitors connected in series built-in according to customer's use.
Hitherto,detector insulator is used to check the cable connected to the electric system " Live or Dead " by lighting neon lamp.
Nowadays, is also used as a sensor to detect zero phase voltage. |

■Line ups |
Since ceramic capacitors are molded with epoxy resin, RISHOCAST detector insulators have excellent insulation reliability in spite of being compact.
Items with capacity of from 7.2kV to 36kV are available as standard.
Customized items to meet customer's specifications are also available. |
