Electrical Three Phase Dry Type Transformer Insulation Class High
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:
|Net distance (mm)||40||60||90||120||160||250|
