The annular iron core is made of amorphous, nanocrystalline, silicon steel and permalloy materials, and is made by spraying and cutting in half.
The open iron core is used in reactors and open current transformers. It has the characteristics of excellent inductance characteristics and anti-superimposed DC bias ability, high saturation magnetic induction intensity, high permeability, high inductance, low loss, small size and weight. Light. Easy to install and other excellent features.
Open current transformers are mainly used in power distribution system renovation projects. They are easy to install, do not need to remove the busbar once, and can also be operated with electricity, which does not affect the normal electricity consumption of customers, saves manpower, material resources and financial resources for user renovation projects and improves efficiency. This series of current transformers can be used with relay protection, measurement and metering devices.
