Product features

The common mode interference and other neutral lines in the power grid can be relieved by setting up a new neutral grounding line in the 800kVA dry-type transformer. The 800kVA dry-type transformer transforms the three line delta connection into the four wire yo system, and the shielding further eliminates the high-frequency pulse interference and noise coupled by the transformer. Although the shielded isolation transformer has the interference (pulse and high-frequency noise) from various N-G sources However, 800kVA dry-type transformer must be correctly and properly grounded, which is very strict, otherwise anti common mode interference will not be effective. Our company can design and produce high quality 800kVA dry-type transformer for customers.

Scope of application

800kVA dry-type transformer is mainly used in the power supply circuit with AC 50-60Hz and voltage below 2000V. It can be widely used in mining enterprises in remote mountainous areas and tunnel construction units (such as conveying pump, shotcrete machine, air compressor, blower, ball mill crusher, winch, water pump) and other high current starting electromechanical equipment. Since it was put into the market, it has been highly praised by mining enterprises and tunnel construction units.

When purchasing products, please clarify the following points:
