Introduced 3 types of stamping dies for manufacturing of manganin shunts: simple dies, combination or compound dies, progressive dies.
By comparison with busbar type current transformer (CT), the structure of toroidal current transformer is simple. Usually, there is a through-hole of no less than 8mm diameter, which allows the primary wire or copper busbar come through. The through-hole may
Spot welding is an important manufacturing technique for our manganin shunt resistors. We use the manganin 6J13 or 6J12 as the calibration material, because of its low temperature coefficient and good thermal stability. However, the price is expensive, we rarely
Copper, Brass, Manganin are the most widely used materials for shunt resistors. As a professional shunt manufacturer, we devoted ourselves to these materials for more than 15 years, and here we introduce them as below. Basic Materials for Shunt Resistors
Current error (amplitude error or ratio error) and phase angle error (phase shift) are two important parameters for a mini current transformer. From the manufacturer’s view, the current error is usually caused by wrong turns number in coil winding process.
The mini current transformer which consists of a busbar and a coil is easy to assemble in an electricity meter or other devices. We can make such kind of component by integrated the ring shape current transformer with a U
For an amorphous core or a nanocrystalline core, mean magnetic path (Lm) and iron cross section (Ac) are two important parameters. Here we’ll introduce them and the calculation method for a finished soft magnetic core. Mean Magnetic Path and Iron
For silicon steel, it’s very easy to make the core by stacking thin stamp parts together. But for brittle amorphous or nanocrystalline, this in not suitable and tape winding is the basic manufacturing technical. Therefore, the height of a tape
Electron beam welding (EBW) plays an important role in the process of shunt manufacturing. In the welding machine, electrons are generated and then accelerated to very high speeds using electrical fields. This high-speed stream of electrons is then focused and
Magnetic latching relays are used to facilitate the remote disconnection and reconnection of power to the consumer premises. A latching relay is a two-position electrically actuated switch. Turning the relay on and off simply requires a momentary application of a
