NAME：LZW32-10/60 on column switch current transformer

Detailed introduction:

Detailed introduction:
LZW series current transformers are suitable for installation on the three-phase outlet of 10Kv on-column switches. They can measure and protect zero-sequence and three-phase currents. According to user requirements, products with different levels of different ratios can be provided.

The core of the zero sequence and measuring winding uses a new magnetically permeable material (ultra-microcrystalline material), which has high magnetic permeability, low magnetic induction and excellent stability, ensuring high measurement accuracy of the transformer. The core of the protective winding is processed by advanced technology using high-quality imported silicon steel sheets to ensure a high accuracy limit coefficient. Silicone rubber is used as the main insulation material, which has excellent insulation, water repellency and aging resistance; high-quality epoxy resin is used between the winding and the main insulation, and between the winding and the winding to ensure high insulation between different windings, stable product performance and maintenance free product.

The series of transformers are divided into two models, type A and type B:

Type A is an arc-shaped interface that can be docked with a column switch;

Type B is a flat interface.
