Electrical Three Phase Dry Type Transformer Insulation Class High 11-0.4kV

Three Phase Dry Type Transformer Introduction


Three Phase Dry Type Transformer , can be used as oil-immersed distribution transformer replacement products, all types of dry-type transformers in the best performance products, especially for urban power grids, high-rise buildings, business centers, theaters, hospitals, Hotels, tunnels, subways, underground power plants, laboratories, stations, docks, airports, combined substations and other important places.


Three Phase Dry Type Transformer Application


Dry type transformer is widely used in local lighting, high-rise buildings, airports, ports, CNC mechanical equipment and other places. We have different types of transformers, they have their own different USES.


Three Phase Dry Type Transformer Feature


Low noise, Low loss, Low temperature rise, better overload capacity, integrated intellectual interface.


Three Phase Dry Type Transformer Installation


1 Before equipment installation, please first refer to the following materials carefully: this manual, nameplate and overall dimensional drawings, thus to get familiar with the product’s total weight and installation methods and prepare corresponding lifting facility and special tools.


2 The transformer should be kept at least 300mm away from walls and other equipment during installation. Transformers installed side by side should have at least 300mm clearance.


3 The minimum safe distance between conductors and ground should conform to IEC76-3-1 POWER TRANSFORMERS-INSULATION LEVELS AND DIELECTRIC TEST-EXTERNAL CLEARANCES IN AIR.


4 The minimum safe distance between the HV coil and ground is listed as follows:


HV voltage £1kV 6kV 10kV 15kV 20kV 35kV
Net distance (mm) 40 60 90 120 160 250
