1500KVA 480V Dry Type isolation Transformer
Engineered by Guangbian, this Energy-Efficient 1500KVA 480V Dry Type isolation Transformer is suitable for converting the standard three-phase 480V grid voltage to the 380V rated voltage required for industrial equipment under applicable operating conditions.
Capacity:1500KVA
input voltage: 480V
output voltage：380V
Frequency: 50/60Hz
Connection: Dyn11
Phase: Three
Cooling method:AF/AN
Winding material: Aluminum / Copper
Impedance voltage:5.5%
No load:≤1.8KW-≤2.2KW(customizable)
Load:≤18.5KW-≤19.2KW(customizable)
This 1500KVA 480V Dry Type isolation Transformer produced by GUANGBIAN is mainly used for voltage matching and electrical isolation protection. Its primary application scenario covers large-scale industrial equipment systems requiring 480V input voltage and 380V output voltage.
The 1500KVA isolationTransformer can accurately convert 480V grid voltage to 380V operating voltage, while providing electrical isolation to isolate and block surge voltages, harmonic interferences and ground fault currents from the primary-side power grid from propagating to the secondary-side circuitry of industrial equipment, thereby protecting large industrial equipment. It also prevents grid instability induced by malfunctions of large industrial equipment and reduces the overall fault risk of the power supply system.
This transformer is widely used in:
● Industrial manufacturing plants
● Commercial buildings
● Data centers
● Hospitals
● Renewable energy projects
● Automation systems
● Mining operations
● HVAC power systems
Its advanced insulation system and vacuum pressure impregnation technology help improve dielectric strength, reduce partial discharge, and extend service life.
