NI-CD SRM BATTERIES

SRM batteries are suitable for numerous rail applications.
They are used for type M discharges (see IEC 60623) i.e. they provide
optimal power for at least one hour.
SRM Ni-Cd batteries use sintered/plastic bonded technology plates.


Benefits

Used by numerous rail equipment manufacturers, Saft's SRM range features many advantages.

• Long battery life
• Two years without water replenishment
• Reduced weight and volume
• Excellent chargeability
• High reliability

Because of these characteristics - especially their long life-time, low maintenance requirement and high reliability - the operational costs of SRM batteries are considerably reduced.

Capacity range of 25 Ah to 440 Ah.

Various configurations available :
• Containers :
steel or stainless steel or polypropylene or FR plastic containers and are ideally suited to the requirements of rail transport.
The stainless steel container is specifically designed for railway rolling stock applications, providing a high resistance to chemical and physical impact.
• Crates :
the steel containers are assembled in wooden crates
the plastic containers are assembled in compact steel crates

Standards
Conforming to international mechanical and electrical standards IEC 60623, IEC 77, NFF 64018, NFF 16101, DIN 40771, and BS 6260.

Plate technology :
SRM Ni-Cd batteries use sintered/plastic bonded technology plates. This technology, developed for rail applications, brings together a sintered positive electrode and a plastic bonded negative electrode (pbe): the very strong positive plate provides very high performance thanks to a perforated steel strip on which nickel powder is sintered. The plates are insulated by means of microporous separators allowing the electrolyte to circulate. This design provides numerous advantages in terms of power, volume, weight and cyclability.
