SANS 1507 SNE Concentric Cable
SANS 1507 SNE concentric cables yog cov cables sib txuas hluav taws xob qis uas tsim tawm raws li South African National Standard (SANS) 1507-6.
Cov xov hluav taws xob SNE Tongxin ua raws li cov lus qhia ntawm SANS 1507, uas npog XLPE (cross-linked polyethylene) insulated cables nrog polyethylene sheathing.
Cov cables no yog siv rau cov khoom siv fais fab nrog Protective Multiple Earthing (PME) systems, qhov twg ib qho Protective Earth (PE) thiab Neutral (N) ua ke - ua ke hu ua PEN - txuas qhov neutral-thiab-av ua ke rau lub ntiaj teb tiag tiag ntawm ntau qhov chaw kom txo qhov kev pheej hmoo ntawm hluav taws xob poob siab thaum muaj PEN tawg. -
SANS 1507 CNE Concentric Cable
SANS 1507 CNE concentric cables ua raws li cov qauv South Africa thiab tau tsim tshwj xeeb rau kev sib txuas lus hauv tsev txhim khu kev qha.
Tus xov tooj cua tooj liab uas muaj hlua khi ua voj voog, XLPE rwb thaiv tsev nrog cov xov hlau av liab qab uas tau teeb tsa ua ke. Cov xov hlau txuas hauv tsev 600/1000V uas muaj polyethylene sheathed. Cov xov hlau nylon ripcord muab tso rau hauv qab sheath. Tsim los ntawm SANS 1507-6. -
ASTM/ICEA-S-95-658 Tus Qauv Aluminium Concentric Cable
ASTM/ICEA-S-95-658 qhia meej txog cov kev cai tsim kho rau cov xov hlau tsis muaj zog tsawg uas ua raws li National Electrical Code (NEC).
Hom neeg xyuas pib no siv tau rau hauv qhov chaw qhuav thiab ntub dej, faus ncaj qha lossis sab nraum zoov; Nws qhov kub siab tshaj plaws ntawm kev ua haujlwm yog 90 ºC thiab nws qhov hluav taws xob ntawm kev pabcuam rau txhua daim ntawv thov yog 600V. -
ASTM/ICEA-S-95-658 Tus Qauv Tooj Liab Concentric Cable
Tus qauv no yog hais txog hom cable uas tau txhais los ntawm ASTM thiab ICEA (Insulated Cable Engineers Association) tus qauv sib koom ua ke.
Tus qauv ASTM/ICEA-S-95-658 piav qhia txog cov xov tooj liab concentric uas muaj lub hauv paus tooj liab, lub tooj liab lossis txhuas concentric neutral concentric, thiab lub hnab tiv thaiv.
Tooj Liab Core Concentric Cable yog ua los ntawm ib lossis ob lub xov hlau hauv nruab nrab lossis cov tooj liab mos mos, nrog PVC lossis XLPE rwb thaiv tsev, cov xov hlau sab nraud ua los ntawm ntau lub xov tooj liab mos mos uas khi rau hauv lub kauv thiab cov hnab dub sab nraud uas tuaj yeem ua los ntawm PVC, thermoplastic polyethylene lossis XLPE.
