The NORATEL is a big company that make toroidal core transformer in Sri Lanka, they find out our company from my customer in China.
NORATEL send us their requirement of toroidal core before order, and we make the mandrel and do the sample according to their requirements, then send sample to Sri Lanka for checking and confirming.
Due to their transfomers is specical, and the toroidal core should be very tight, so we must modify our machine, we changed the design of machine frame which make the machine more strong,
and then we changed the winding driver/motor with big power instead of the previous driver/motors. and we also make the change for the brake system on the decoiler.
Customer visit our company to inspect the RC150-50 machine after we finsh the machine, and they feel happy to see the tight toroidal core by the making of modified machine.
At last, we packed and shipped the RC150-50 automatic toroidal core winder to NORATEL COMPANY in May.2019.
