YBH-40.51.14-10000 Huash式 Box-type Substation
The box transformer is divided into three parts: the high-voltage chamber, the low-voltage chamber, and the transformer itself, arranged in a "目" shape. Except for the transformer heat sink and the body that protrude outside the box, all other live compartments are sealed within independent chambers. Each chamber is isolated into independent compartments with partitions, and there is a lower manhole in the box for easy installation and maintenance.

Product Overview
The box transformer is divided into three parts: high voltage chamber, low voltage chamber, and transformer, arranged in a "目" shape. Except for the transformer heat sink and the body exposed outside the box, all other live intervals are sealed in independent compartments. Each chamber is isolated into independent intervals with partitions, and there is a lower manhole in the box for easy installation and maintenance.
The inner and outer surfaces of the box are smooth, with no rust, coating peeling, or collision damage. The coating layer is firm and uniform, with no obvious contrast or reflection.
The base of the box and all exposed metal parts are treated for corrosion and rust prevention, and a durable protective layer is sprayed.
The top cover of the box is equipped with a rainproof sealing cover and a rain eave, and the double-layer structure of the top cover can prevent thermal radiation.
The design dimensions of the box door match the size of the installed equipment. The box door uses internal hinges, and all doors on the box open outward with an opening angle greater than 90°.
The box is made of stainless steel, and the paint is imported automotive paint, all using baking paint method, which is smoke-proof, moisture-proof, mildew-proof, and has strong outdoor weather resistance. The area where the photovoltaic power station is located has low temperatures, large temperature differences, high humidity, and strong winds and sand. The box transformer has a reasonable protective structure, dust-proof structure, and low-temperature resistance, meeting the requirements for normal and safe operation under harsh environmental conditions.
