Tender Overview

Rashtriya Chemicals And Fertilizers Limited (RCF), under the Department Of Fertilizers, seeks a service provider for the complete rewinding and testing of a 1900KW, 11KV Mitsubishi vertical induction motor. The motor must be dismantled, rewound with copper conductors, and tested across multiple electrical and mechanical checks. Work includes transportation to the vendor workshop, replacement of bearings with SKF-certified units, stator winding varnish as per standard, and witnessing by an RCF representative. The project specifies rigorous acceptance tests and coordination for stator re-staggering with quality control witnessed during commissioning.
