NF-360        

Brief introduction

VRLA Battery(NF-360)for internal-combustion locomotive is researched and developed by Shuangdeng Grouptogether with Locomotive Research Institute of Development Academy of Ministry of Railway.The post seal of the product adopts the patent technology and has quite high assembly and open valve pressure which can reduce water loss to a great extent. Compared with traditional VRLA Battery, NM-360 has a lot of advantage, such as good start-up ability under low temperature, high specific energy, safer and longercycle life. It can be the most ideal power source asinternal-combustion locomotive start-up, illumination and other standby power source system.

    The product is executed in accordancewith the industry standards issued by Ministry of Railway of P.R. China GB/T 7404.2—2013“Valve-regulated Lead-acid Accumulator for Diesel Locomotive”.  

Structure Characteristics

     Perfect seal of post: unique structure of triple seal(patent: ZL 02 2 20024.X) to totally prevent the acid leakage.
