Customized Primary Wire Shunt
Customized Primary Wire Shunt

The multi strand wires can brazed with manganin shunts, and enlarge the applications. We can also assemble them with toroidal current transformers and provide the whole set. With more than 15 years’ experience, we can design and manufacture customized wire shunts of different complicated structures, while multi strand wires’ gauge and length can be specified by end users. We can also provide EBW shunts,  the main parts which have the calibration function, as semi-products to customers.
