Qhov Zoo Ntawm Cov Hluav Taws Xob Hluav Taws Xob?

Dec 31, 2017

Cov kwj deg hluav taws xob muaj ntau lub qauv, xws li cov roj, KV, KVZ thiab cov khoom siv hluav taws xob ntxig khoom, thiab lwm yam zoo rau ntau lub tsev ntawm lub tsev, cov cuab yeej, tus choj, qhov av, teeb pom kev zoo thiab kom zoo dua. Lub "flexible electrical conduit" txais tau tus qauv tsim, tsim thiab tsim kho ntawm JG / T3053-1998 "flexible hlau xaim tiv thaiv casing". Kev pom zoo ntawm "China Engineering Engineering Standardization Association Standard CECS87: 96" cov cuab yeej hlau nplaum hluav taws xob "thawj cov qauv" rau thawj lub sijhawm hauv Suav teb los ua "cov hlau nplaum hluavtaws" yog xyoo 1992, vim tias nws qhov tshwj xeeb zoo, yuav sai sai no rau ntau lub teb, tau txais kev qhuas thiab qhuas. Sib piv nrog cov "flexible fais conduit", tag nrho cov kub-dip galvanized steel strips yog ua los ntawm kev sib tw, sab hauv txheej yog nplaim hluav taws kub txheej, uas ua rau lub nplhaib retardancy, dej tsis kam, corrosion kuj thiab tensile thiab compressive zog.
