large-scale construction projects, and other
fields. QUNENG SCB10-630 SCB10 series resin dry-type
transformerDry-type transformer: relies on air convection for
cooling, generally used for local lighting and electronic circuits.
Transformers such as mechanical equipment, in the power system,
general steam turbine transformers, boiler transformers, ash
removal transformers, dust removal transformers, desulfurization
transformers, etc. are all dry-type transformers, the
transformation ratio is 6000V/400V and 10KV/400V, used for rated
voltage 380V load. Simply put, a dry-type transformer refers to a
transformer in which the iron core and winding are not immersed in
insulating oil. SCB10 series dry-type transformer

features of dry-type isolation transformers:iron coreThe
high-quality cold-rolled grain-oriented silicon steel sheet is
used, and the iron core silicon steel sheet adopts a 45-degree full
oblique joint so that the magnetic flux passes along the joint
direction of the silicon steel sheet.Winding form1, winding2, Epoxy
resin plus quartz sand filling and pouring3, Glass fiber reinforced
epoxy resin casting (i.e. thin insulation structure)4 multi-strand
glass fiber impregnated with epoxy resin winding type (generally 3
is used because it can effectively prevent the poured resin from
cracking and improve the reliability of the
equipment) Technical parameters of dry-type transformers1.
Frequency of use: 50 / 60HZ;2. No-load current: < 4%;3.
Dielectric strength: 2000V/min without breakdown; test instrument:
YZ1802 pressure tester (20mA);4. Insulation grade: F grade (special
grade can be customized);5. Insulation resistance: ≥2M ohm test
instrument: ZC25B-4 type megger
