Product Description

 

General

JBK3 / 5 series machine tool control transformer is the latest transformer series introduced by Germany in the mid-1990s. Based

on domestic JBK3 series machine tool control transformers, it has further absorbed similar foreign products over the years, and

has optimized the terminal structure of advanced foreign methods. The terminals and the skeleton are combined together to

increase the protection level to IP2LX to prevent accidental contact with the circuit. Using domestic IT cold-pressed terminal

blocks, the wiring method can make the wiring denser.

The connection between the silicon steel sheet and the silicon steel sheet of the transformer, and the silicon steel sheet and the

bottom plate are all welded by argon arc welding to form a whole, which is simple and clear. In particular, the bottom plate is formed

at one time and the installation size is more accurate than the JBK3 series. The use of high-quality corrosion-resistant alloy

materials greatly improves the reliability of grounding performance and comprehensively improves the product quality. The product

complies with VDE0550, IEC204-1, IEC439, JB / T9446-1999, GB5226 and other relevant international and national standards,

and won the European Community "CE" certification, the United States "UL" certification. Interchangeable with foreign products.
