CSPs, uas tau qhia thawj zaug thaum xyoo 1980s, muaj cov tub ntxhais uas muaj fiber ntau-reinforced polymeric (FRP) core thiab cov vaj tsev elastomeric. Txoj kab uas hla ntawm FRP core yog li ntawm 45 mus rau 100 hli, nrog qhov siab tshaj plaws ntawm qhov tsis tshua muaj siab tshaj 130 hli. Daim ntawv thov ntawm CSPs nyob rau hauv substations stemmed los ntawm yav dhau los siv ntawm composite kab post (CLP) insulators, feem ntau nyob rau hauv lub tebchaws United States. CSPs nrog cov cores khoom yog feem ntau ua hauj lwm nyob rau hauv voltages txog 245 (420) kV. Txawm li cas los xij, rau cov chav kawm hluav taws xob ntau dua, lawv daim ntawv thov dav dav yog txwv vim muaj kev cuam tshuam cov neeg kho tshuab siab. Tus qauv xeem rau cov khoom no yog IEC 62231, thaum lub tshuab thiab hluav taws xob cov yam ntxwv tau txhais hauv IEC 62231-1, uas kuj suav nrog ANSI hom siv hauv North America. Tus qauv tsim nyog rau hom ANSI yog C29.19.

At voltage classes higher than 245 kV, the height and bending moment of station posts both increase. Consequently, meeting application requirements using solid core CSP designs (i.e., with core diameters >170 mm) xav tau kev siv zog loj. Qhov no ua rau cov thev naus laus zis no tsis tshua muaj nqi sib tw piv rau hom porcelain. Tib lub sijhawm, cov khoom sib xyaw hollow core chaw nres tsheb (CHSP) thiab hybrid chaw nres tsheb ncej (HSP) insulators tau pib tshwm sim hauv daim ntawv thov no. Piv txwv li, CHSPs twb tau siv nyob rau hauv 800 kV HVDC thiab 1100 kV UHV daim ntawv thov, featuring txuas ntev ntawm tshaj 10 m thiab raj diameters li ntawm 500 mus rau 1000 mm. Khoov lub sijhawm tshaj 1000 kNm yog ua tiav nrog cov thev naus laus zis no. Lub hollow ntim nyob rau hauv cov ncej no yuav tsum tau sau nrog ib tug hluav taws xob inert nruab nrab xws li insulating gas ua npuas ncauj. Cov qauv xeem siv tau rau cov no yog IEC 62772.

| Kev tu | Nws tuaj yeem txo cov nqi kev ua haujlwm ntawm txoj kab, txo hluav taws xob poob, thiab kev siv zog ntawm kev siv. |
| Qhov loj thiab qhov hnyav | Qhov loj me me thiab lub teeb yuag (kwv yees li 1/7 txog 1/10 qhov loj ntawm qhov sib npaug porcelain insulator hlua), lub kaus tiab nthuav tawm cov elasticity zoo heev, tiv taus kev tawg, ua kom yooj yim kev thauj mus los thiab kev teeb tsa, thiab raug nqi zoo. |
| Mechanical Load | Lub fiberglass tub ntxhais pas nrig muaj lub zog tensile siab, uas yog 5 mus rau 10 npaug ntawm cov ntaub ntawv ceramic. Vim yog qhov me me ntawm tus pas nrig, cov khoom muaj qhov me me thiab lub teeb yuag, siab khoov lub zog, thiab yooj yim los tsim cov khoom loj tonnage ntau tshaj 300kN. |
| Lub sij hawm xa tuaj | Cov txheej txheem tsim khoom yog yooj yim, thiab lub sijhawm xa khoom luv luv. |
