Product Structure Features
◆ change the basic structure of the box is divided into "head" shape and "goods" shaped, box frames are made of high-quality channels and angles welded, high mechanical strength, making the box with aluminum profiles, with better corrosion resistance, the overall aesthetic appearance by painting coloring can harmonize with the surrounding environment, the bottom of the lifting device designed to transport mobile installation provides great convenience.
There are separate high-pressure chamber, transformer chamber and the low ◆ box changes within each room lighting automatically opens with the open door. When equipped with a high-pressure high-voltage indoor ring network equipment, according to user need to use compressed air type / vacuum load switch, and has the "Five Anti" feature, when a high-voltage current-limiting fuses with a fuse with a fuse, load switch automatic gates, avoiding the run phase and cause malfunction.
◆ transformer room with natural ventilation and cooling automatically controlled forced air cooling system with temperature-dependent and automatic control of the exhaust system, which can effectively reduce the inside temperature control to meet operational requirements, according to user requirements can also be used to prevent condensation device, according to the user's requirements, it may be convenient access from both sides of the door from the transformer compartment along the track. Box material to prevent rain and dirt, with the conditions of long-term outdoor use, ensure that the preservative waterproof, dustproof performance, long life, easy maintenance, beautiful appearance.
◆ transformer can be dry or oil-immersed transformers, oil-immersed transformers can be used in two oil and oil-free pillow pillow completely sealed.
◆ low pressure chamber has the overall functionality and low voltage switchgear, for the user to select any combination.
◆ Housing material: shell material has a composite plate, stainless steel composite panels, aluminum coated zinc plate, stainless steel, metal carved panels.
◆ structural features: High reasonable and compact structure, the choice of SF6, FZN57, VHC RMU, all with five parties interlock function.
Transformers natural ventilation and automatic ventilation cooling system applied dry and oil-immersed transformers.
◆ low-pressure chamber: You can adopt a variety of structures of power distribution scheme according to user requirements, power distribution, lighting, power distribution, automatic reactive power compensation, energy metering and other various functions, equipped with automatic lighting system.

Base map
◆ base plane should be looking for a flat place;
The number and orientation of embedded steel base within
◆ determined by the user according to the number and position out of the cable;
◆ cable infrastructure within the proper bracket, embedded iron and support should be grounded;
◆ ground rod is determined by the number of soil conditions, we must ensure that the grounding resistance is less than 4Ω;
◆ grounding wire and grounding connections shall be welded and brushed asphalt preservative;
Location of the user
◆ stepping stairs custom box changes according to the position of the door; (see layout)
◆ pit depth and the other to determine the size of the visual installation conditions;
◆ basis for reference only, the user can modify the actual situation.
