When the above normal service conditions cannot meet the usage requirements, the user shall negotiate with the manufacturer.
Product characteristics
The basic structure of the substation is classified into “目” and “品” shapes. The box framework is welded with high-quality channel steel and angle steel, with high mechanical strength. The box is made of aluminum alloy profiles, which have good anti-corrosion ability. The overall beautiful appearance can be coordinated with the surrounding environment through painting and coloring. The carefully designed bottom lifting device provides great convenience for installation, transportation and movement.
There are independent high-voltage room, transformer room and low-voltage room inside the substation, and the lighting in each room automatically opens with the opening of the door. The high-voltage room is equipped with high-voltage ring main unit, which can be selected as compressed air type or vacuum load switch according to user needs, and it also has the "five prevention" function. When current-limiting high-voltage fuse is used, if a phase fuse is blown, the load switch will automatically open, avoiding faults caused by phase loss operation.
The transformer room adopts natural ventilation and automatic control forced cooling device, with exhaust system that automatically controls with temperature changes, which can effectively control and reduce the temperature inside the box to meet operational requirement. According to user requirements, anti-condensation device can also be used, which can be easily accessed from both sides of the transformer room through the door along the track. The box material can prevent rainwater and dirt from entering, and has the conditions for long-term outdoor use, ensuring anti-corrosion, waterproof and dustproof performance, long service life, simple maintenance, as well as beautiful appearance.
① Transformers can be dry-type or oil immersed type.
② The low voltage room has the overall function of low-voltage switchgear, which can be selected and combined by users at will.
③ Outer shell material: including composite plate, stainless steel composite plate, aluminum zinc plated plate, stainless steel plate and metal carved plate.
④ Structural feature: The high-voltage structure is reasonable and compact, and HXGN17 and XGN15 ring main units can be selected, all of which have five prevention interlocking functions. The natural ventilation and automatic ventilation cooling system for transformer can be applied to dry-type and oil-type transformers.
⑤ Low voltage room: Multiple structural distribution solutions can be adopted according to user requirements, including power distribution, lighting distribution, reactive power automatic compensation, energy metering and other functions, and it's equipped with an automatic lighting system.

Frequently Asked Questions (FAQ)
What are the normal environmental conditions required for installing this substation?
The substation should be installed at an altitude of ≤1000m, within an ambient temperature range of -15℃ to +40℃. Daily average relative humidity must not exceed 95% (monthly average ≤90%). The installation site must be free from fire, explosion hazards, conductive dust, chemical corrosive gas, and severe vibration.
What types of transformers can be used in this substation?
The substation is highly flexible and can accommodate both dry-type and oil-immersed type transformers depending on the user's specific operational needs.
What materials are available for the outer shell of the substation?
The outer shell is available in several durable materials, including composite plates, stainless steel composite plates, aluminum-zinc plated plates, stainless steel plates, and metal carved plates.
How does the substation handle temperature control and cooling inside the transformer room?
The transformer room is equipped with a natural ventilation design combined with an automatic control forced cooling system. The exhaust system automatically triggers and adjusts based on temperature changes to effectively control and reduce the internal heat.
What protective and safety features are integrated into the high-voltage room?
The high-voltage room features a compact structure with "five prevention" interlocking functions. It uses high-voltage ring main units (compressed air or vacuum load switches) and current-limiting high-voltage fuses. If a phase fuse blows, the load switch automatically opens to prevent faults caused by phase loss.
What is the protection level and noise level of this substation?
The conventional substation product has a protection level rating of IP33D and maintains a low noise level of ≤50 db during operation.
