The product is fully enclosed and equipped with complete structure without requiring insulation clearance to ensure personal safety.It is suitable for both looped and terminal network and can be changed conveniently for an enhanced reliability of power supply.Outstanding performance of transformer: low noise, low loss, low temperature rise, strong capability to withstand overload , short circuit and lighting.The cable connector can be operated at load current of 200A and operated as load switch under emergency circum-stances. It also has features similar to isolating switch.Adopt double fuse protection to reduce operating cost, and the plug fuse is fuse of double sensitivity (temperature and current).Due to use of oil with high ignition point (R-TEMP oil, the igniton point is up to 312ºC), it can be used in building and eliminate risk of fire.Adpot Dyn11 connection and three-phases and five-poles structure with advantages such as high quality of voltage, no displacement of neutral point, low noise and good lightning protection.Main technical dataNumberItemUnitTechnical parameters1Rated voltagePrimary sideKV6~10Secondary sideKV0.42Highest working voltageKV123Rated frequencyHZ504Rated capacityKVA100~125051-min power frequency withstand voltageKV356Lightning impulse withstand voltageKV9572 second short time withstan currentA128Interrupting capacity of back up high voltage current limiting fuseKVA509no-load tap changer(6~10)±2×2.5%10Ambient temperatureºC-20 ~ +4011Allowable temperature riseK55
