66 ~ 110kV Sab nraum zoov Composite Porcelain Insulator Terminal

66-110kV sab nraum zoov Composite Plhaub insulator davhlau ya nyob twg yog ib qho kev txiav tawm cable siv los txuas siab -voltage cables (feem ntau cross-linked polyethylene, XLPE insulated cables) ntsuas ntawm 66kV lossis 110kV los ntawm hauv av los yog hauv cov txee rau cov khoom siv hluav taws xob sab nraud lossis cov khoom siv hluav taws xob sab nraum zoov ntev ntev, nrog rau cov khoom siv hluav taws xob sab nraum zoov.

Nws cov yam ntxwv tseem ceeb yog kev siv "cov ntaub ntawv sib xyaw" (High -Temperature Vulcanized Silicone Rubber, HTV) tsim los ntawm kev txhaj tshuaj molding txheej txheem los tsim cov rwb thaiv tsev sab nraud bushing thiab sheds, hloov cov tsoos porcelain bushing.

Yam ntxwv	Composite Plhaub Sab nraum zoov Termination	Tsoos Porcelain Plhaub Termination
Khoom siv & Luj	Silicone rubber composite khoom, hnav (~ 1/10th qhov hnyav ntawm cov plooj (porcelain), yooj yim thauj thiab nruab.	Cov khoom siv ceramic, hnyav thiab tsis yooj yim, tsis yooj yim rau kev tswj thiab teeb tsa.
Pollution Flashover Resistance	Zoo heev. Silicone roj hmab yog hydrophobic, tiv thaiv cov kab mob los ntawm kev tsim cov yeeb yaj kiab dej tsis tu ncua, ua kom muaj zog flashover zoo heev. Haum rau Chav Kawm IV uas muaj kuab paug hnyav heev.	pluag. Porcelain nto yog hydrophilic, yooj yim tsim ib tug nruam conductive zaj duab xis thaum muaj kuab paug thiab ntub dej, ua rau flashover; yuav tsum tau ntxuav tas li.
Kev tawg -Cov pov thawj & Kev nyab xeeb	Superior. Cov ntaub ntawv sib xyaw yog hloov tau; txawm nyob rau hauv cov teeb meem sab hauv, lawv feem ntau tawg es tsis tawg, ua kom cov khib nyiab tsawg, ua kom muaj kev nyab xeeb dua.	Qhov qis dua. Porcelain vaj huam sib luag tuaj yeem tawg vim muaj kev ua txhaum sab hauv, tsim cov khoom puas tsuaj, cov cuab yeej tsim kev puas tsuaj thiab cov neeg ua haujlwm.
Seismic Performance	Zoo. Cov khoom siv elastic tuaj yeem nqus tau kev co, haum rau thaj tsam seismic lossis siab -ib puag ncig kev co.	pluag. Ceramic yog nkig thiab muaj zog seismic tsis kam.
Huab cua Resistance	Zoo heev. Resistant UV, ozone, thiab huab cua kub / qis (-50℃rau +50℃+).	Zoo, tab sis huab cua thermal cycling tuaj yeem ua rau glaze tawg.
Installation & Kho	Feem ntau prefabricated, yooj yim installation, siab standardization. Maintenance-dawb lossis tsawg-kev tu.	Kev teeb tsa nyuaj, tej zaum yuav xav tau ntawm -site pouring. Yuav tsum tau ntxuav kom huv.
Manufacturing & Tsim	Ua kom muaj kev sib xyaw ua ke; saj zawg zog optimization ntawm shed puab thiab creepage nrug.	Constrained los ntawm ceramic firing txheej txheem; txwv kev hloov pauv.
