Frequency Conversion Resonance Test Device
Variable Frequency Resonant Device
Brief introduction
BPXZ-DL series portable variable frequency resonance boosting device for cable makes the reactor and the tested capacitor in resonance by adjusting the power supply, to get from the tested equipment. Now it is a new method and trand for high voltage test and widely used both at home and abroad.
Product features
◆Because of the number of 35KV and blow voltage cable used, test workload is heavy, withstand test device with small volume and light weight is needed.
◆Portable cable withstand test system was born.
◆This system is required that the weight of the part for a single man remove is not more than 30kg and for two men is not more than 60kg. Suitable for site handling.
◆Use 220v or 380v single phase power supply, convenient to take power on site.
◆Reactor use the method of epoxy resin casti with nice appearance and reliability, can meet the requirements of all kinds of cable.
◆Withstand test of 110kv and blow voltage cable use oil immersed reactor, when the unit weight is over 100kg, can choose to equip with the special small electric crane of our company.
