Features & Advantages

 


Core


The core is manufactured with high quality cold rolled grain-oriented silicon steel of high magnetic conductivity. 45° mitring and 5-steps overlapping structure is adopted for the core design, thus to greatly reduce no-load loss and no-load current.

 

To precisely calculate resonance frequency and intensity and avoid cavity resonance generated by the core structure during operation, simulation analysis is carried out for core mould design. Flexible connections are made between core and coils, core and bogie. With these measures adopted, the noise level is reduced by 10~15dB compared with the international standard.

HV winding


HV winding is manufactured with high quality copper wire, reinforced with glass fiber and being casted with epoxy resin at vacuum state with pressure, having the resin fully impregnated into the coils in the most professional imported equipment. Therefore, product's partial discharge is especially low, for example, transformer of 10kV-level has a partial discharge less than 5 pC.

 

During the HV winding design, rational structure is adopted to improve the electric distribution. With the lighting impulse wave simulation calculation and analysis being carried out with special auxiliary software, product's anti-lightning impulse capacity is greatly improved.

LV winding


LVwinding (with the rated power equal to or higher than 400kVA) is manufactured with high quality foil conductor, resulting in excellent ampere-turn balance, low transverse magnetic flux leakage and higher anti-short circuit capability. By designing reasonable air conduit in the windings to increase the heat-dispersion surface, transformer's temperature rise is effectively controlled and the overload capacity is greatly improved.

Transportation


 For product without special package or with only simple package, attentions should be
paid during transportation to avoid any rain, snow or other foreign subjects falling into
the product.

 

 During transportation, product inclination should not be larger than 15°.

 For product equipped with carriage, please dismantle the roller to avoid product
displacement during the transportation.

 

 During product lifting, please lift the product by using the four padding block under the
four corners of the package bottom. If there is no package for the product or when lifting
the product from the package, please use the lifting lugs on the main body. Please be
noted that the angle between the wire rope should not be larger than 30°.
Inspection and Acceptance
After the product arrives at customer’s site, please inspect the product for acceptance.

nameplate conform to those written in the contract, for example, product model, rated
power, rated voltage, rated current and etc..

 Check the document accompanied with the product.
With reference to the packing list, check the components and accessories.
 Check whether there is nay damage on the product and displacement of the component
of components. Check the cables to know whether there is any loosing, crack, insulation
damage or polluted.
After the inspection for acceptance and if the product will not be put into service immediately,
please re-pack the product and store it in a safe place, thus to equipment safety.
