Railway applications. Mounted parts of the traction transformer and cooling system - Pump for insulating liquid for traction transformers and reactors not-for-sale It aims to ensure quality1 Scope This Technical Specification covers requirements for electric pumps which generate the circulation of insulation liquid in traction transformers and reactors of rail vehicles and their associated cooling system. The pumps covered by this Technical Specification are rotodynamic pumps driven by a squirrel cage induction motor which is immersed in the insulating liquid. CLC TS 50537 2 gives consideration to both technical and normative
