underground distribution transformer

1. product introduction
s (b) underground distribution transformer is a kind of transformer which combines the transformer and the corresponding auxiliary equipment, and is installed under the outdoor reference plane which has no direct contact with the public, and can operate in water in a certain period of time. underground transformer has the function of power transformation and distribution, and can also be equipped with high and low voltage cabinets on the ground, which can replace the traditional substation.

2. product parameters

◆ totally enclosed outgoing line structure, with overall protection grade of ip68, which can be immersed in water for safe operation
◆ surface anti-corrosion treatment, never rust
the oil tank can be made of 304 stainless steel or anti-corrosion treatment by hot galvanizing process, and the surface is covered with marine paint to strengthen anti-corrosion, with long service life, safety and reliability.
