In December 2018, during the expansion project of DEH power plant, KNTECH provided 180 sets of waterproof telephone knsp-18 and waterproof acousto-optic bell ringing device D13. The waterproof telephone and waterproof acousto-optic bell ringing device successfully solved the poor communication caused by the damp, rain and other conditions of the power plant.
