MHYBV cable yog ib qho classic thiab tseem ceeb cable hom rau mine kev sib txuas lus systems, dav deployed nyob rau hauv thee mines, hlau mines thiab lwm yam underground qhov chaw nrog explosive gas cua.
Tus qauv ua raws li lub teb chaws tus qauv naming cov cai:
MH:Mine kev sib txuas lus cable
Y:Polyethylene rwb thaiv tsev
B / V:PVC hnab
Nyob rau hauv luv luv, MHYBV hais txog mine kev sib txuas lus cable nrog PE rwb thaiv tsev thiab PVC sheath.Cov nram qab no yog cov ncauj lus kom ntxaws qhia txog cov yam ntxwv nta, kev specifications thiab daim ntawv thov cov txheej txheem.
Specifications thiab cov qauv nta
MHYBV cable yog cov kws tshaj lij tsim los hloov mus rau qhov hnyav hauv av mine nrog cov qauv tsim thiab kev ua haujlwm.
Tus coj
Annealed saj zawg zog tooj liab conductor yog saws, featuring zoo heev conductivity thiab yooj yooj yim nteg thiab routing nyob rau hauv complex underground roadways.Common cross-sectional ntau thiab tsawg: 0.5 mm², 0.75 mm², 1.0 mm², xaiv raws li kis tau tus mob nrug thiab teeb liab attenuation.
Rwb thaiv tsev txheej
Ua los ntawm HDPE (High Density Polyethylene) thiab cov khoom siv polymer siab.
Cov qauv kab hluav taws xob
Ntau cov insulated cores (5 khub, 10 khub, 20 khub lossis ntau dua) raug tso tseg rau hauv cov tub ntxhais cable.Twisted khub qauv yog tus qauv tsim, uas zoo txo cov kev cuam tshuam ntawm cov hlua hlau thiab txhim kho kev sib txuas lus zoo.
Txheej txheej
Lub tsho sab nrauv txais yuav cov khoom siv PVC, nrog lub zog txhua yam, ua kom tsis muaj zog, tiv thaiv corrosion thiab nplaim retardancy.Flame retardant kev ua tau zoo yog qhov tseem ceeb ntawm kev nyab xeeb rau kuv cov cables: nws tuaj yeem ua tus kheej - tua sai sai tom qab tawm hauv qhov hluav taws kub thiab tiv thaiv hluav taws sib kis raws kab kab.
Main Electrical & Environmental Specifications
- Nominal ua hauj lwm capacitance: Tsawg tshaj los yog sib npaug rau 0.06 μF / km, tsawg capacitance txo cov teeb liab attenuation thiab ncua kev sib kis deb
- Rwb thaiv tsev tsis kam (20 degree): Ntau dua lossis sib npaug rau 10000 MΩ·km ib tus tub ntxhais rau lwm cov cores thiab cov ntaub thaiv npog
- Kev khiav hauj lwm kub: -10℃~ +50 degree
- Yam tsawg kawg nkaus tso cai bending vojvoog: Ntau dua lossis sib npaug li 15 npaug ntawm kab kab sab nraud
Main Application Scenarios
MHYBV yog tsim los rau kev ruaj khov nyob rau hauv underground coal mines:
- Mine dispatch kev sib txuas lus: Txuas qhov chaw xa khoom nrog cov chaw ua haujlwm hauv av, xws li lub ntsej muag mining, tunneling heading thiab substation, ua haujlwm tseem ceeb hauv kev sib txuas lus rau kev ruaj ntseg cov lus txib.
- Kev tshaj tawm hauv av: Siv rau kev tso tawm cov lus qhia kev nyab xeeb, suab paj nruag keeb kwm yav dhau thiab ceeb toom ceeb toom xwm txheej ceev hauv kuv qhov chaw.
