Product Overview
Outdoors integrated distribution cabinet series is suitable for AC 50 Hz, rated voltage up to 0.4 kV power transmission and distribution system. This series of product is a combination of automatic compensation and power distribution. And it is an innovative indoors and outdoors pressure distribution cabinet of electrical leakage protection, energy metering over-current, over-pressure open phase protection. It has benefits of small volume, easy installation, low cost, electricity-stolen prevention, strong adaptability, resistance to aging, accurate rotor, no compensation error, etc. Therefore it is the ideal and preferred product for electric grid reformation.
Product Shell
The product is made of bending and welding of high quality stainless steel. Compared with other distribution boxes made of cold steel, its tensile ability, oxidation resistance, corrosion resistance has been greatly strengthened, and it extends the service life of the equipment. Novel design shows scientific innovation and achievements. On the other hand, v-type box is equipped with sealing rubber strip, which can prevent the dust, and it is fitted with floor at the same time. It can be installed electrical equipment. The open angle is greater than 90 degrees. It is adopted the new design: waterproof, anti-theft, anti-dust. And organic glass has been adopted to increase safety, easily installation and operation.

Technical Requirement
For dimensions, please refer to the actual dimensions of American style substations. The concrete foundation should have a flat surface, and American style substations should be fixed on the foundation using pressure plates;
The form of grounding bars and cable fixing brackets can be determined according to the actual situation. Cable fixing brackets and grounding bars should be pre-embedded; The position of cable holes for incoming and outgoing lines depends on the specific situation. After the installation of American style substations, there must be a gap of no less than 1.5m on the front of the switch for easy operation;
The grounding grid can be made of 12 galvanized round steel or 40x4 galvanized flat copper, and the grounding resistance should meet the requirements of the power department.
