STS (Cov Qauv Hloov Hloov Kho) yog los ua cov duab qhib qhib hauv South Africa hauv xyoo 1993, pib rau hluav taws xob them nyiaj. Tom qab ntawd, nws tau tso tawm los ntawm IEC (International Electrotechnical Commission) raws li International Standign) raws li tam sim no nws tseem muaj dav siv hauv dej thiab roj meters. Sts Smart them ua ntej ntsuas dej sib txuas ua ke rau kev siv thev naus laus zis los muab cov dej dej khov kho thiab txhim khu kev daws teeb meem.

Cov ntsiab lus zoo
Ntxiv nrog rau cov haujlwm yooj yim ntawm cov khoom them ua ntej dej, cov copper cov yeeb nkab them ua ntej ntsuas dej muaj cov laj thawj hauv qab no.
Kev sib haum:Pom kev cuam tshuam ntawm cov khoom sib txawv uas tsim los ntawm cov chaw tsim khoom sib txawv ntawm cov khoom ua ntej, tawg cov teeb meem ntawm hom - tsis sib thooj.
Cov ntaub ntawv yooj yim hloov:Kev hloov chaw hauv dej / ntim ntawm ib qho 20 - tus lej token hloov cov ntaub ntawv sab nraud (token-tsawg), uas ua kom yooj yim cov ntaub ntawv xa cov txheej txheem.
Kev Siv Dej Yooj Yim:Txhawb kev hloov pauv ntawm kev them ua ntej thiab cov qauv xa rov qab. Cov neeg yuav khoom tuaj yeem yuav cov dej los ntawm cov chaw tsim khoom ntawm POS lossis nyiaj ntsuab} {{{- kev them nyiaj, rooj sib tham tau kev ua haujlwm ntau yam.
Vim li cas xaiv cov kav dej tooj liab
Piv nrog yas - dej yeeb nkab metres, tooj yeeb nkab them ua ntej ntsuas dej yog qhov zoo hauv qab no.
Lub zog siab kuj, haum rau khaub thuas & dej kub:Nrog kev kub siab (feem ntau 2.0MPA), ua haujlwm rau ob qho tib si txias thiab dej kub}}}}} sawv dej dej.
Cuam Tshuam - istable & ruaj:Tooj liab yog tawv thiab muaj zog, tsis yooj yim tawg thaum ntaus thaum ntaus thaum lub sijhawm thauj mus los lossis siv, ua kom muaj kev pabcuam ntev dua.
Kub - istant thiab fireproof:Tsis muaj kev cuam tshuam los yog tawg ntawm qhov kub thiab txias, me me thermal expansion / consaction, zoo hluav taws kub tsis kam txo cov hluav taws kub.
Ntev - lub sij hawm stability:Tsis yooj yim rau xeb nyob rau hauv feem ntau cov dej zoo; Txawm hais tias "tooj liab ntsuab dej" yuav tshwm sim nyob rau hauv dej tshwj xeeb, nws tseem ntau ruaj dua li qee cov yas metres tom qab kev kho mob tom qab kev kho mob.
