For customers' urgent requirement, we stock various Grade of oriented electrical steel.

◆   Our high efficient slitting machine equipped with

tungsten blade can slit oriented electrical steel coils

(almost burr free) for wound core processing.

◆   Use the best automatic core winding machine to process cores and the most efficient Bell type furnace to anneal cores. Implement accumulated 30 years technical experience to manufacture high quality step lap cores.

◆ Characteristics of cores are as follows:

1. Excellent magnetic properties, low core loss and low exciting current

2. Low noise level

3. Easy of core/coil assembling, high efficiency

4. Reliable in dimensions accuracy

◆   Step lap cores manufactured by our company are suitable for arge and small capacity single phase, three phases, core form and shell form, oil immersed, dry type, cast resin molded distribution transformers, and such as pole type, pad mounted and underground transformers.

◆   Core joints are assembled from a plurality of groups. Each group repeats the same pattern of the step lap configuration with others. The location of the joints, which depends upon the size of the core (either core form or shell form), can be at the top of the core or at the core leg. The customer can specify the joint location.

◆  A standard core width is identical from inside to outside. the same width. However if there is a need in changing the widths, (either inside wraps or outer wraps of the core), the customer can specify width dimensions.

When placing an order, please provide the following information below：

◆   Core design drawing (dimensions, weight, built up thickness and joint location)

◆   Magnetic characteristic (guarantee value and calculated value)

◆   Test conditions (Test voltage per turn and Frequency)
