Using the environment
◆ Altitude: ≤2000m(more than 2000m need to reduce capacity for use, manufacturing contact with the factory);
◆ ambient temperature: -40℃~+55℃;
◆ Temperature: maximum monthly average temperature +30℃, maximum annual average temperature +35℃;
◆ Relative humidity: daily average ≤95%, monthly average ≤90%;
◆ Shockproof level: horizontal acceleration 0.4m/s², vertical acceleration 0.15m/s²;
◆ Installation location: no violent impact, serious pollution and chemical corrosion, no conductive dust and explosion danger places.
◆ When can not meet the normal use conditions, please consult with our company to solve.
Features of product structure drawing
Pieces change the basic structure of the box is divided into "eye" and "product" glyph, glyph skeleton box body is made of high quality channel steel and Angle steel welded together, has high mechanical strength, the box body made of aluminum alloy profile has good anticorrosion ability, beautiful appearance after spray paint color can be in harmony with the surrounding environment, designed at the bottom of the lifting device, to install mobile provides great convenience of transportation.
◆ The box transformer has an independent high voltage room, transformer room and low voltage room, each room lighting automatically open with the door opening.High voltage room is equipped with high voltage ring network switch equipment, according to user needs to choose pressure/vacuum type load switch, and has the function of "five prevention", when the current limiting high voltage fuse is used, when a phase fuse is broken, the load switch automatically split, to avoid the fault caused by the lack of phase operation.
Pieces transformer chamber adopts natural ventilation and automatic control of forced cooling air cooling device, varies with changes in temperature and exhaust system of automatic control, control can effectively reduce the temperature in the cabinet, to meet operation requirements, according to user requirements can also adopt the condensation prevention device, according to the requirements of users, is along the track can be conveniently from the pressure chamber between the both sides from the gate in and out.The box material can prevent rainwater and dirt from entering, with long-term outdoor use conditions, ensure anti-corrosion and waterproof, dustproof performance, long service life, simple maintenance, beautiful appearance.
◆ Transformer can be used dry type or oil-immersed transformer, oil-immersed transformer can choose two kinds of oil pillow and oil-free pillow fully sealed.
◆ Low voltage chamber has the overall function of low voltage switchgear, for users to choose, any combination.
◆ Shell material: shell materials are composite plate, stainless steel composite plate, aluminum zinc plate, stainless steel plate, metal carved plate.
◆ Structure features: high pressure structure reasonable and compact, can choose SF6, FZN57, VHC.KYN28 center cabinet and ring network cabinet all have five-way interlocking function.
Transformer natural ventilation and automatic ventilation cooling system can be applied to dry and oil immersed transformers.

◆ Low voltage room: according to user requirements using a variety of structure of power distribution scheme, power distribution, lighting distribution, automatic compensation of reactive power, electric energy metering and other functions, equipped with automatic lighting system.
