Product Specifications:

Nanocrystalline magnetic cores for instrument current transformers are widely used in low-voltage, medium-voltage and high-voltage instrument current transformers. Magnetic cores include annular, rectangular, and racetrack types. The packaging methods are divided into: stainless steel + PCB shell, DMC plastic shell, epoxy resin packaging, crepe paper packaging, etc. Please download standard core specifications.

The magnetic core can be customized according to the customer's specifications and drawings. The parameters required for customization include:

1. Core size, case size

2. Current transformer turns ratio

3. Capacity (VA)

4. Accuracy



The main purpose:

Nanocrystalline alloy transformer cores are widely used in precision current transformers with precision levels of 0.2, 0.2s, and 0.1 because of their excellent magnetic properties such as high magnetic permeability, high saturation magnetic induction, and low cost. Transformer, gas-insulated or oil-immersed switchgear, low-voltage, medium-voltage, high-voltage switchgear, power system, power system, relay protection, power monitoring device, etc.
