Duk kungiyar IEC a cikin fanni na insulator da aka sanya ta hankali na ƙasashen China sun fito.

A kan wanda, wasu IEC standards da dama masu muhimmanci game da insulators, wadanda China ta fi shugabancin haka a lokacin farko, suka fitar da kwaikwayen. Wannan standards suna cikakken bayanin coupling markings, dimensions, da kuma tests na end fittings na insulators, musamman IEC 60120:2020, IEC 60372:2020, da IEC 60471:2020. Wasu standards masu uku suka samun amfani da 'yan sana'a da tarihi masu National Technical Committee on Insulators of China (SAC/TC80). Fitar da wannan standards yana nuna abubuwan da ya faru a cikin tashar da mafi girma a cikin insulator manufacturers na China da ke yi aiki a tashar international standardization, wanda ya zama da tasirin a gaba-gaban ilimi da takardun technology da international influence a fagen insulators.

Wannan lokaci, a cikin gidajen da ke yi waɗanda ke kusa da ultra-high-voltage (UHV) da extra-high-voltage (EHV) power transmission da transformation projects, rating da mechanical strength na insulators na 530 kN na baya ba zai iya tabbatar da magance aiki ba. A cikin gyaran national standards GB/T 7253 da GB/T 4056, an san ratings da mechanical strength na 700 kN da 840 kN zuwa levels masu standard don insulators, wadda suke nuna ball-and-socket coupling structures, dimensions, da kuma gauges na amsa da suka buƙata. Daga ma'ana haka, SAC/TC80 ta yi rashin tsarin da interchangeability na hardware na insulators a cikin national standards na China, wanda ya ci gaba da rashin tsarin da SAC/TC80 ta son yi a cikin development da gyaran standards na IEC don in iya amfani da ilimin advanced da practical experience na China a wannan fagen.

A Oktoba 2016, a cikin IEC/TC36 annual meeting da aka yi a Frankfurt, proposal na China ta shahara, wanda ya haɗa shi a matsayin process da Working Group IEC/TC36 MT21. 'Yan committee masu SAC/TC80 suna yi aiki a matsayin conveners na working group. Don in taimaka wa conveners, SAC/TC80 ta koordinationi a yi establishment na domestic counterpart working group don IEC/TC36 MT21, wanda ya ba conveners da members na international working group da taimaka mai kyau a cikin ilimi. A Afrilu 2017, MT21 working group, wanda an yi a matsayin experts daga China, France, Japan, Spain, Switzerland, da wasu orin, ta fitar da kwaikwayen da ke yi aiki.

Daga ma'ana haka, a cikin joint efforts na Chinese expert team, bayan five domestic working group meetings da three international working group meetings da ke yi aiki a matsayin discussions, China ta yi amfani da multiple innovative achievements da operational experiences na UHV insulator technologies na China zuwa clauses na IEC standards. Wannan sun hada da practical engineering experience daga UHV projects na China game da two new coupling markings—designated as “36” and “40”—da ke nuna higher mechanical strength ratings.

Manufacturers na insulators na China suna daidaita da ita da technological innovation da leadership a fagen industry, suna yi aiki don in zama reliable builders na national key projects da pioneers a fagen power transmission da transformation technology innovation. Suna zama backbone na China's power transmission da distribution equipment manufacturing industry da ya rubuta chapter mai kyau a cikin journey na China's power equipment manufacturing sector—from catching up to surpassing to achieving world-class status. A cikin leading industry development, manufacturers na insulators na China suna da authority mai kyau a cikin formulating da gyaran standards.

Sunana primary drivers behind technical product standards na high-voltage electrical apparatus, capacitors, insulators, surge arresters, da kuma major contributors zuwa transformer-related standards. Suna undertake domestic secretariat responsibilities don multiple IEC technical committees (and subcommittees), suna host IEC/TC28 international secretariat, da kuma chair IEC/SC22F, representing China a cikin international standard-setting activities. A lokacin da 2019 ta kammala, suna participate da kuma lead formulation da gyaran 460 standards (including international, national, and industry standards), among which 31 were international standards. Fitar da standards na IEC insulators masu uku yana nuna first-time leadership na China a fagen insulators, kuma yana nuna global outreach na Chinese standards.
