YB□-12 type combined substation, is based on the actual operation status of the domestic distribution network of China Science and Technology Corporation.It summarizes the years of experience in field service and design and construction of the distribution network, digests and absorbs advanced domestic and foreign Technology and design concepts, new products developed independently. It has excellent performances such as reasonable design, reliable power supply, compact thread structure, convenient installation and flexible operation.It is mainly aimed at the ring network system and urban power grid with a voltage level of 10K.It is suitable for industrial and mining enterprises, airports, stations, ports, highways, Subway, residential area and other public places.

1、GRC cabinet ★ The cabinet is based on advanced GRC (glass fiber reinforced cement material) construction technology, using cement glass fiber and quartz sand as the main raw materials, and adopts mold-based integral molding to produce branches, which has many in terms of wood formulation and production process. Technical know-how, no dust vaporization in the production process, in line with environmental protection and labor insurance standards;
★ This product can successfully solve the problem of the corrosion of the outer shell caused by the falling of the paint layer and the condensation of the surface of the electrical equipment in the box due to the change of the ambient temperature. With unique ventilation design, the temperature rise grade of natural ventilation can reach 10K;
★ The production process of moulded integral ring type pre-mixed casting is adopted, which meets the current energy saving and environmental protection requirements. Short production cycle has the characteristics of high overall mechanical strength, light weight, exposure to sunlight, noise reduction, beautiful shape, easy coordination with the environment, etc;
★ Solved the problem of the external remote meter reading antenna of the metal box.

2、Shell of cold-rolled steel plate ★ The shell is composed of high-quality channel steel, angle steel and steel plate, combined with advanced heat insulation principle and air duct design and implementation of the quasi-generation processing mode, which not only has strong resistance to sunlight radiation, but also solves the problem of non-powered exhaust box variable ventilation The contradiction between heat dissipation and dust prevention to avoid harmful condensation, and provide safe and reliable external protection for internal electrical components, the protection level reaches P43;
★ The top of the box adopts double-layer structure, which has functions of heat insulation, heat preservation and anti-supply dew drip. At the same time, the top of the box can be easily lifted, and the transformer and high and low voltage equipment can be placed from top to bottom.

3、Outer layer of curved plate type spraying ★ The whole structure adopts cold-rolled steel plate and channel steel;
★ The double-layer structure of the top and door guards is used to effectively prevent the appearance of condensation and the excessively high internal temperature caused by sun exposure;
★ The door plate of the transformer room adopts the curved plate labyrinth ventilation hole, the ventilation volume is increased and it is used in combination with the blind window ventilation hole, which enhances the visual effect.

4、Jinbang board shell ★ It is mainly based on cement, fly ash, silica fume, and perlite, added with composite fiber reinforcement, extruded by vacuum high pressure, and cured by high temperature steam pressure, fine processing and multi-layer coating. to make. It has many advantages such as green environmental protection, light weight and high strength, sound insulation and heat insulation, water and fire resistance, cold resistance and frost resistance.
★ The whole cabinet adopts the skeleton composed of high-strength steel (I-beam) to form a basic load-bearing frame to ensure that the cabinet has excellent seismic and wind resistance.

★ Altitude: ≤1000m;

★ Ambient temperature: -25℃~40℃, the highest average daily temperature does not exceed 35℃;

★ Relative temperature: daily average value ≤95%; monthly average value ≤90%;

★ Outdoor wind speed: ≤35m/s;

★ Ground tilt: ≤3°;

★ Installation location: No explosion hazard, fire, chemical corrosion and vibration.
