From China to the world

Whether it’s the rapid­ly grow­ing demand for elec­tric­i­ty, the ener­gy tran­si­tion or digitalization—the com­plex­i­ty of the require­ments placed on trans­former man­u­fac­tur­ers is increas­ing. Nan­tong Hyosung Co. Ltd. from Chi­na has there­fore entered into a strate­gic part­ner­ship with MR and can now offer lean sys­tem solu­tions to a glob­al clien­tele.

Trans­form­ers from Nan­tong Hyosung Co. Ltd. are already hum­ming in over 70 coun­tries, ensur­ing a reli­able pow­er sup­ply. The trans­former man­u­fac­tur­er, which belongs to the Kore­an con­glom­er­ate Hyosung, pro­duces in the megac­i­ty of Nan­tong in Chi­na for pow­er gen­er­a­tors as well as pub­lic and indus­tri­al net­work oper­a­tors world­wide. Three-quar­ters of its pro­duc­tion goes abroad.

Nan­tong Hyosung faces sim­i­lar chal­lenges like many oth­er trans­former man­u­fac­tur­ers: Grid devel­op­ment is very dynam­ic around the globe. Every­where, the demand for elec­tric­i­ty will rise sharply in the com­ing years—due to the grow­ing pop­u­la­tion, but also because of new loads brought about by the elec­tri­fi­ca­tion of the mobil­i­ty and heat­ing sec­tors. Added to this are the fluc­tu­a­tions caused by the inte­gra­tion of renew­able ener­gies. In order to be able to con­trol these devel­op­ments, dig­i­tal solu­tions and thus intel­li­gent resources are increas­ing­ly in demand. And any­one who sup­plies the whole world, like Nan­tong Hyosung, must also com­ply with numer­ous dif­fer­ent nation­al reg­u­la­tions. In short, the trans­former busi­ness is becom­ing more com­plex. And also more demand­ing. On the oth­er hand, cus­tomers are demand­ing low­er costs, short deliv­ery times, and pro­fes­sion­al ser­vice.

Strategic partnership with MR

So how can this com­plex­i­ty be man­aged? Jae Seong Jang, Gen­er­al Man­ag­er of Nan­tong Xiaox­ing Trans­former Co. says, “Robust tech­nolo­gies, cus­tomized designs and excel­lent project exe­cu­tion are part of our busi­ness phi­los­o­phy. In order for us to deliv­er on this promise in the future, we need cost-effec­tive com­plete solu­tions.” So the Chi­nese trans­former man­u­fac­tur­er entered into a strate­gic part­ner­ship with MR. “MR is the world mar­ket leader and offers a com­pre­hen­sive range of trans­former-relat­ed solu­tions that are already spec­i­fied for glob­al use and meet inter­na­tion­al stan­dards,” says Jang.

In addi­tion to on-load tap-chang­ers, sen­sors and pro­tec­tion devices, it is pri­mar­i­ly the ETOS® sys­tem solu­tion for dig­i­tiz­ing pow­er trans­form­ers that helps Nan­tong Hyosung serve its demand­ing cus­tomer require­ments. Since it works on the plug-and-play prin­ci­ple, it not only reduces pro­duc­tion costs. It also elim­i­nates the need for many cables and on-site assem­bly work. Since all com­po­nents come from a sin­gle source, order­ing process­es are also more effi­cient. And the part­ner­ship offers yet anoth­er advan­tage: Since MR has a world­wide ser­vice net­work, oper­a­tors who use trans­form­ers from the Chi­nese man­u­fac­tur­er also ben­e­fit. Jang is con­vinced: “All in all, the coop­er­a­tion is a clas­sic win-win sit­u­a­tion for all par­ties involved.” 

Spanish solar power

The project:

An inter­na­tion­al plan­ning office real­ized a solar park in the Extremadu­ra region of Spain in 2022. Four trans­form­ers were ordered from Nan­tong Hyosung for the sub­sta­tion that feeds the solar pow­er into the trans­mis­sion grid.

The requirement:

Nan­tong Hyosung was look­ing for a com­plete solu­tion that includ­ed on-load tap-chang­ers as well as oth­er trans­former acces­sories and a dig­i­tal mon­i­tor­ing sys­tem.

The solution:

MR was able to pro­vide a com­pre­hen­sive solu­tion con­sist­ing of on-load tap-chang­ers, MSENSE® intel­li­gent sen­sors, ETOS® trans­former oper­at­ing sys­tem, and MESSKO® acces­sories. The com­plete pack­age can also be offered as a stan­dard pack­age for future projects.

Grid expansion in Mozambique

The project:

The state-owned ener­gy com­pa­ny Elec­t­ri­ci­dade de Moçam­bique (EDM), is expand­ing its net­work and need­ed trans­form­ers for five new sub­sta­tions.

The requirement:

EDM pre­ferred a glob­al renowned man­u­fac­tur­er for the trans­former acces­sories, pro­vid­ing reli­able prod­ucts with local avail­abil­i­ty and ser­vices.

The solution:

MESSKO® MTRAB® 2.5 main­te­nance-free dehy­drat­ing breather and the online oil analy­sis device MESSKO® DGA 9 are used in the trans­form­ers, thus increas­ing oper­a­tional reli­a­bil­i­ty.

Digital in Texas

The project:

560 GWh of elec­tric­i­ty will be pro­duced annu­al­ly by a solar farm in Fayette Coun­ty, Texas, when it goes online in late 2023. Nan­tong Hyosung was con­tract­ed to sup­ply trans­form­ers for the sub­sta­tion at the facil­i­ty.

The requirement:

The plan­ning office was look­ing for a dig­i­tal solu­tion to mon­i­tor the trans­form­ers.

The solution:

The open sys­tem solu­tion ETOS® is con­fig­ured in a way that it can also be used as a stan­dard solu­tion in fol­low-up projects of the end cus­tomer.
