1. Main purposes: concrete-type current limiting reactor, commonly known as cement reactors for large capacity power distribution device, installed in the bus or feeder outlet, as the current limiting short-circuit current can also be used for rectifier device As the filter reactor or motor start to do when the current limiting reactor.
2. Structural features: concrete column current limiting reactor with two terminals per phase, respectively, and the current and load connection, the use of PVC flame-retardant insulation aluminum cable winding between the layers and turn the air gap, the turns evenly Fixed to the concrete column, the bottom of each concrete column are equipped with support porcelain seat.
3. Arrangement combination: three-phase vertical, two-phase vertical one phase parallel flow, three-phase level.
4. Conditions of Use: Ambient temperature does not exceed 40℃, temperature limit does not exceed 80℃, less than 1000 meters above sea level, indoor use.
