Product Parameters
1.Brief Introduction:
The YB series preinstalled substation is a compact complete distribution device that combines high-voltage electrical equipment,transformers,low-voltage electrical equipment,etc.It is used in urban high-rise buildings,urban and rural buildings,luxury villas,square parks,residential areas,high-tech development zones, small and medium-sized factories,mines,oil fields,and temporary construction sites to receive and distribute electricity in the distribution system.This product meets the standards of GB/T17467 "High Voltage/Low Voltage Prefabricated Substation"and SD320 "Technical Conditions for Box Substation".
2.Product description:
The YB series preinstalled substation is a series of products designed and developed by our company to meet the needs of urban network construction.This series of products is a combination of medium voltage switchgear and transformer complete set of power distribution equipment consisting of a certain wiring scheme and low-voltage distribution equipment.
This series of preinstalled substations is suitable for three-phase systems with a rated frequency of 50HZ and a capacity of 1600KVA or less in residential communities,commercial hotels,large construction sites,high-rise buildings, industrial and mining enterprises,and temporary construction sites.They are suitable for ring network power supply and also for radial terminal power supply.
This series of prefabricated substations has the advantages of compact structure,strong completeness,safe and reliable operation,convenient maintenance,and beautiful appearance.It has the advantages of small volume,small flour area,large selectivity,small on-site installation volume,short installation and debugging cycle,and moving with the load center.

◆ The air humidity shall not exceed 90%(+25℃);
◆Gas places without conductive dust,explosion hazards,corrosive metals and electrical components;
◆ Outdoor wind speed shall not exceed 35m/s.
5.Product design features:
◆The shell is designed based on advanced foreign technology and actual situations.It is sturdy,insulated and ventilated,with good performance,dust prevention,small animal prevention,beautiful appearance,and easy maintenance Characteristics such as defecation.There are multiple options for shell materials.For example, aluminum alloy plates,steel plates,load plates,stainless steel plates,non-metallic materials(glass fiber cement),etc.
◆The high-voltage side generally adopts load switches or vacuum circuit breakers,and has complete anti miss operation functions.If optional:XGN20-12L sulfur hexafluoride ring network Cabinet,HXGN15A,HXGN17 and other ring network switchgear.Transformers can be oil immersed,fully sealed,or dry type.Low voltage room equipment can Select GGD type.
◆The substation has complete protection performance,convenient operation,and high and low voltage metering options.It can be equipped with automatic no power compensation devices according to user requirements.
◆The top cover of the box is designed as a double-layer structure,and the interlayer is filled with foam plastic, which has a good thermal insulation effect.The high and low voltage rooms are designed with independent top plates inside,which can transform the pressure Anti condensation and automatic temperature control monitoring, heating,and cooling devices are installed in the equipment room.
◆The box adopts natural ventilation or can be equipped with forced ventilation equipment.Dust prevention devices are installed at the positions corresponding to the louvers on the outer side of the door panels and side panels.
6. Installation,use,maintenance,order:
◆After the product is suspended on the foundation,tighten the anchor bolts,and then install the inlet and outlet wires.After comprehensive inspection,power can be transmitted;
◆To replace the high-voltage fuse,the load switch should be disconnected first before opening the door for operation and maintenance;
◆When checking,the power should be cut off first and carried out according to the instructions.
◆When ordering,it is necessary to indicate the model,specification,quantity,electrical component model, specification,and shell paint color;
◆If the user has any other requirements,they can contact each other during the ordering process.
