|Description:||Traction motor are divided into:Traction motor,Traction generator,Auxiliary motor which are mainly used in railway electric locomotive,Industrial and mining electric locomotive,Electric power transmission diesel locomotive and so on.
GPO-3 sheet,FR-4 sheet is mainly used as insulating structurs in motor,movable cover plate,slot wedge which will greatly improve the safety and stability of motor ,and simplify the structure ,minimize the the volume and weight.It is more applicable to satisfy the commends of the space and weight.
GPO-3 and FR-4 can promote the power output ,enhanced overload capacity,reduce noise,extent the rang of speed,save the power 20%-30%.
Main famous cooperative enterprises:CRRC Zhuzhou electric motor Co.,Ltd and its subordinate processors,Alstom Equipment Co. Ltd
Our company is located in Xiang’an manufacture base of Xiamen Special Economic Zone.It is a national hi-tech enterprise with the ability to R&D,production,sale and further processing,we has became the solver of electric insulation technology project .We have more than one hundred machines including CNC and Digital controlled lathe.every kinds of Bending machine,Punching machine,have establish the completely production chain of design and precision further processing .We are the only modernization company in the country which is totally operated by Numerical control in respect of material production and the process for non-metallic insulating spare parts.All of the products have gained the UL certification of the USA,The French national standard certification,CEMT,RoHS,Reach and many national& international authoritative organization certification.
