Cast Resin Dry-Type Power Transformer has high performance of
energy- saving, small dimension, low weight, damp-proof, flame
retardant, strong over-load competency and automatic
temperature controlling ability. It can be widely used in power
transmission systems, hotels, restaurants, high-rise buildings,
commercial centers, gymnasiums, petrochemical plants, the
underground railway stations, airports, offshore drilling
platforms and other places. Its performances will be more
prominent if applying in the limited places where installation
must be closed to load center and special fire prevention
occasions. The product technical specifications fully comply
with standard GB******6, IEC**6. GB/T*********7 and DlN
****3.
Highlights
High voltage winding is filled with grade F insulation
material. Its surface is enclosed by Cast resin under vacuum,
curing to form a solid whole body with high mechanism strength,
no part electricity discharge, high reliability.
Resistance of fire, explosion-proof, no air- pollution,
environmental protection, can be installed in the load
center.
The coil does not absorb moisture. Iron core and clamping piece
can run in the 9% relative humidity and other harsh
environment, no need dehumidify under intermittent operation
after special process.
Strong ability of circuit shorting resistance, anti-lightning
impulsion and overload.
Thin resin insulating layer of inside and surface of coil, good
heat dissipation. The cooling mode commonly used natural air
cooling (AN). For any protection grade transformer, it can be
equipped with air-cooled system (AF).
Small dimension and occupation, light weight, easy installation
and free maintenance.
