Casing Spacer
Khoom Description
Cov ntaub ntawv dav dav
Hauv ntau lub teb chaws, cov kav dej hla los yog khiav mus rau txoj kev loj thiab kev tsheb ciav hlau raug tiv thaiv los ntawm casing. Casing Insulators yog siv los cais cov kav xa dej los ntawm cov kav dej, nws tsim nyog rau dej thiab roj & roj cov kav dej.
Khoom nta / Cov txiaj ntsig:
* High hluav taws xob insulating tus nqi thiab tsis tshua muaj dej nqus, yog li tiv thaiv kom tsis txhob muaj hluav taws xob sib cais ntawm cov cab kuj thiab casing.
* Ribbed puab nto tiv thaiv slippages thiab tiv thaiv cov txheej puas.
* Siab compressive zog los txhawb nqa cov yeeb nkab hnyav.
* Tiv thaiv kev puas tsuaj thaum raug rub mus rau hauv lub casing.
* Resistant rau txhua yam thiab thermal shocks thiab kev ntxhov siab, tshwj xeeb tshaj yog tshwm sim thaum lub sij hawm installation thiab inserting ua hauj lwm.
