Introduction

YB-PRE Compact substations series(European box variable) Product Introduction
YB type compact substations and says Europe type box change,GB17467-1998 product conforms to the high and low voltage substation "and IEC1330 preinstalled type,such as a new standard for power distribution equipment,it than conventional civil substation has many advantages.Because of its small volume,cover an area of an area small,compact structure,easy to move,thus greatly shorten the construction period and covers an area of,also reduced the infrastructure expenses.Meanwhile,the box-type convering stations on site installation is simple,rapid,equipment maintenance simple power substation,without special,especially it can further load centers,to improve the quality of power supply reduce power loss,enhance the reliability and power of distribution network re-election are improtant.Complete electricty transformation change box,the distribution,transmission,measurement,compensation,system control,protection and communications function.

By high-voltage switchgear YBengineering-type substation,low-voltage distribution screen,distribution transformer and shell with a combination of four section,high-pressure air load switch,transformer for dry type transformer or oil-immersed transformer.Cabinet adopted good insulation ventilation structure,appearance beautiful generous,heat insulation performance is good,and the upper body sets,outdoor ventilated for every shot ducts and high or low voltage transformer room temperature can reduce the room caused to a minimum.The cabinet to furnish temperature control forced ventilation device and automatic temperature control device sun.Each independent units installed perfect control,protection,charged display and lighting system.

YB-PRE Compact Substations Series(European Box Variable)Application Scope
Applicable to below 35KV voltage,etc,the main transofrmer capacity 5000KVA and below small substations,widely used in substation halling city industry substation,consumers 10KV ring net system,rural 35KV substation and so on.

YB-PRE Compact Substations Series(European Box Variable)Main Function
Complete electricity transformation,distribute,transmit,measurement,compensation,the system of control,protection and communications functions.

YB-PRE Compact Substations Series(European Box Variable)Main Features
Will the primary and secondary equipment installed a protable sealed,temperature control,anticorrosive moistureproof antirust the cabinet,arriving at the just installed in cement basis.Has less investment,construction period is short,covers an area of less,easy and harmontous environment etc.Characteristics.
