Shantou Hi-Tech Zone Arrow Power Mfg.Ltd., established
in Shantou, China in November 2000 with its headquarter
Hong Kong, specializes in the development and manufacture
of R-Core and R-Core Transformer. Our annual production
capacity for R-Core and R-Transformer are 24 million pcs.
and 8 million pcs. respectively. The majority of our
equipments are imported from Japan and U.S.A., and our
Know How Technology is originated from Japan.
Most of our products have achieved UL, C-UL, VDE and CCEE
Approvals . We also dedicate our efforts to tailor made
products for various applications. To make sure that customer
needs are being met, we interact closely with our customers
to understand and satisfy their different needs and requirements.
Our major markets are China, Europe and U.S.A currently.
Nowadays, many famous branded hi-end products make use of
our R-Transformer to upgrade their performances and efficiencies.
Besides, some hi-end products dealers also apply our R-Core
and R-Transformer to new development in technology. It is
evident that the efficiencies and accuracies of our products
are highly regarded in the market; and our products become
more and more popular in the industry.
R-Core transformer is a revolutionary breakthrough in transformer
structure which employs grain-oriented steel material for
cutless circular cross section R-core. The best performance
of R-core transformer can be specified as following:
Small Power Consumption
The R-core transformer, with its rational design, features
low iron loss, low heat generation, little exciting current
and small power consumption. These are limitation of no-load
for application in adapters under long-time stand-by power
Against Leakage Flux
The R-core has only very small leakage flux because the
steel core has no magnetic gaps and the wire is wound with
good balance. It is the reason why there is no need to devise
any countermeasure against leakage flux.
Since there is no cutting, magnetostriction stress is absorbed
easily. It assures that there is practically no noise.
By using high grade Hi-B Grain-oriented silicon steel and
constructing the R-core Transformer with minimum distance
between core and winding, efficiency of the R-Core is usually
more than 90%, and its performance in the instantaneous
power is good enough.
