Box-type transformer is an economical, reasonable, safe and scientific distribution device in the current distribution system. The high-voltage side of box-type transformer is 10 (6) kV, and the low-voltage side is 0.4kV three-phase AC 50Hz outdoor complete set of equipment. It is a pre-installed and movable distribution device integrating high-voltage switch, transformer low-voltage switch and intelligent control.

• Product Introduction:

       XB - 10 series of metal boxes change summary over the years my company for the manufacture of the box-type substation, on-site service and operation maintenance experience, on the basis of the domestic use of advanced electrical equipment and technology, design and develop new box products, in addition to a common box of features, such as economy, safety, compact, can meet the needs of the frequent lifting movement, external force damage prevention.

This kind of box has compact structure, small floor space, low investment, short station construction period and light weight. Portable, less waste, strong set, easy to install and use, can be used for many times.
The outer shell is made of aluminum-zinc steel plate or stainless steel plate imported from Luxembourg, with strong mechanical bending, impact resistance and tensile strength. Good corrosion resistance, anti - corrosion for more than 20 years. Anti-sun, anti-low temperature, with a strong heat insulation, moisture-proof and flame retardant ability.
Long service life, filled with fire and heat insulation material lined with heat insulation material, can prevent solar radiation; The box is equipped with cooling, heat preservation and anti-condensation equipment. Various communication equipment, integrated automatic equipment, image monitoring equipment, load control equipment can be arbitrarily configured.
The case was a change to adapt to the harsh island, beach, beach, gobi and desert areas, can be widely used and some municipal construction, residential quarters, factories, hotels, parks, oil field, the airport terminal, railway, shops, street lighting power supply and other outdoor projects and poor transportation condition in the region as accept, transformation and distribution of electric energy, is a kind of beautiful, economic flow, affordable, easy to transport and fixed installation of new type of substation.

Service environment:
 

1、Ambient temperature: -25℃~+40℃;

2、Altitude: ≤1000m, 3000m if special ordered transformer and low-voltage components are used;

3、Vertical tilt: ≤3°;

4、Relative humidity: ≤90% (+25℃);

5、Household pressure: ≤700 Pa;

6、No conductive dust, corrosive gas, explosion, fire and violent shaking place.
