Lub resistivity coefficient ntau dua 10 rau lub zog ntawm 9 Ω.Cov khoom siv CM yog hu ua cov khoom siv hluav taws xob hauv cov cuab yeej hluav taws xob, nws lub luag haujlwm yog cais cov peev txheej ntawm cov ntsiab lus sib txawv hauv cov khoom siv hluav taws xob.Yog li ntawd, cov ntaub ntawv insulating yuav tsum muaj cov khoom siv hluav taws xob zoo, uas yog, cov rwb thaiv tsev siab thiab compressive zog, thiab tuaj yeem tiv thaiv kom tsis txhob tawg, creepage los yog tawg thiab lwm yam xwm txheej; Thib ob, lub tshav kub kuj yog qhov zoo, tshwj xeeb tshaj yog tsis yog vim lub sij hawm ntev thermal ua (thermal aging) thiab kev ua tau zoo hloov pauv yog qhov tseem ceeb tshaj plaws; Tsis tas li ntawd, nws muaj thermal conductivity zoo, noo noo tsis kam, siab mechanical. lub zog thiab yooj yim processing.etc.

1. Kev faib tawm ntawm cov ntaub ntawv insulating

Cov ntaub ntawv rwb thaiv tsev feem ntau siv hauv hluav taws xob engineering tuaj yeem muab faib ua cov ntaub ntawv inorganic insulating, organic insulating cov ntaub ntawv thiab cov ntaub ntawv sib xyaw insulating raws li lawv cov khoom sib txawv.

(1) inorganic insulating cov ntaub ntawv: mica, asbestos, marble, porcelain, iav, sulfur, thiab lwm yam, feem ntau yog rau lub cev muaj zog, hluav taws xob winding rwb thaiv tsev, hloov phaj phaj thiab insulator, thiab lwm yam.

(2) organic insulating cov ntaub ntawv: shellac, resin, roj hmab, paj rwb, ntawv, hemp, txhob lo lo ntxhuav, rayon, feem ntau yog siv nyob rau hauv lub tsim ntawm insulating xim, winding hlau coated rwb thaiv tsev, thiab lwm yam.

(3) cov ntaub ntawv rwb thaiv tsev sib xyaw: ua tiav los ntawm ob hom ntaub ntawv saum toj no ua los ntawm ntau yam molding rwb thaiv tsev cov ntaub ntawv, siv los ua lub hauv paus ntawm cov khoom siv hluav taws xob, lub plhaub, thiab lwm yam.(Cov ntaub ntawv rwb thaiv tsev tsim los ntawm peb lub tuam txhab-Jiujiang Xinxing rwb thaiv tsev khoombelongs rau cov khoom siv rwb thaiv tsev: iav ntaub + cob)

2. Thaum tshav kub kub tsis kam qib ntawm cov ntaub ntawv insulating

(1) Qib Y insulating cov ntaub ntawv: ntuj textiles xws li ntoo, paj rwb thiab fiber ntau, textiles raws li acetate fiber thiab polyamide, thiab cov ntaub ntawv tshiab uas tsis muaj decomposition thiab melting point.Limit kub khiav hauj lwm: 90 degrees.

(2) Qib A cov ntaub ntawv rwb thaiv tsev: qib Y cov ntaub ntawv uas ua haujlwm hauv cov roj ntxhia thiab impregnated nrog roj lossis oleoresin composite kua nplaum, rwb thaiv tsev thiab roj pleev xim rau enameled hlau, enameled daim ntaub thiab lacquer hlau.Asphalt xim, thiab lwm yam. Txwv kev khiav hauj lwm kub: 105 qib.

(3) Cov ntaub ntawv rwb thaiv tsev qib E: polyester zaj duab xis thiab A chav kawm cov khoom sib xyaw, iav ntaub, oily resin xim, polyvinyl acetal high-strength enameled hlau, vinyl acetate tshav kub-resistant enameled hlau. Txwv kev khiav hauj lwm kub: 120 degrees.

(4) Qib B insulating cov ntaub ntawv: polyester zaj duab xis, mica, iav fiber ntau, asbestos, thiab lwm yam., impregnated nrog tsim nyog resin bonding, polyester xim, polyester enameled hlau. Txwv kev khiav hauj lwm kub: 130 degrees.

Cov khoom tseem ceeb yog:3240 daj epoxy phenolic fiberglass ntawv , G10 lub teeb ntsuab epoxy fiberglass ntawv, thiabFR4 fireproof lub teeb ntsuab epoxy fiberglass ntawv

(5) Qib F rwb thaiv tsev: nyob rau hauv cov organic fiber reinforcement ntawm mica cov khoom, iav ntaub plaub thiab asbestos, iav ntaub, iav fiber ntau daim ntaub thiab asbestos fiber raws li laminated khoom nyob rau hauv cov ntaub ntawv inorganic li reinforcing thiab pob zeb nrog ntxiv dag zog rau mica hmoov khoom tshuaj thermal stability zoo. los yog alkyd polyester cov ntaub ntawv, composite thiab silicone polyester xim. Txwv kev khiav hauj lwm kub: 155 degrees.

Peb cov ntawv tseem ceeb Qib F rwb thaiv tsev yog3242 ib,ib 3248,G11,FR5thiab347F benzoxazine iav fiber ntau laminated ntawv

(6) Qib H insulating cov ntaub ntawv: mica cov khoom uas tsis muaj kev txhawb zog los yog ntxiv dag zog los ntawm inorganic cov ntaub ntawv, F-class thickened cov ntaub ntawv, composite mica, organosilicone mica khoom, silicone silicone roj hmab polyimide puas iav ntaub, composite film, polyimide xim, thiab lwm yam. Kub: 180 degrees.

Peb cov ntawv tseem ceeb qib H rwb thaiv tsev yog3 250

(7) Class C insulating cov ntaub ntawv: inorganic cov ntaub ntawv uas tsis muaj cov organic nplaum thiab tus neeg saib xyuas qib impregnants, xws li quartz, asbestos, mica, iav thiab porcelain cov ntaub ntawv, thiab lwm yam. Txwv kev khiav hauj lwm kub: saum toj no 180 degrees.
