Khoom Ntawv

Daim ntawv thov

Tsim mus rau past530, cov cavalation yog qhov muaj kev nyab xeeb thiab tsim kom siv cov ntaub ntawv sib txuas lus thiab ib puag ncig cov txheej txheem kev xa khoom ntawm cov cim ntawm cov teeb tsa. Cov cim taw tes tuaj yeem yog qhov analogue lossis digital los ntawm ntau yam ntawm cov sensors thiab transducers.

Nta:

1. Tus neeg xyuas pib tus tub ceev xwm, qhov ntau thiab tsawg: 0.5 mm² khoom, 1.0 mm² khoom, 0.5 mm² hloov tau, 0.5mm allible

2. Rwb thaiv thaiv: Polyethylene PE, xim code: Dub / dawb / Liab; nrog cov kab xev rau hauv qab cov kab xev ntawm trarter screen

3.Thiab screen: 24 μm Aluminium / PetP cov kab xev tshaj tinned tooj liab ntws hlau, 0.5 mm², qhwv: tsawg kawg 1 txheej ntawm cov kab xev yas

4. Cov vijtsam sib xyaw: 24 μm aluminium / petp kab xev tshaj tinned tooj liab ntws hlau, 0.5 mm²

5. Lub txaj: xoom halogen nplaim retardant compound lszh, dub

6. Armor: Galvanized Hloov Hloov Hlau Xov Tooj

7. Sab nraud sheat: xoom halogen nplaim retardant compound teb lszh, dub lossis xiav rau kev nyab xeeb zoo nkauj

Daim Ntawv Qhia Ib Leeg Ib Leeg Kev Siv Khoom Siv Hluav Taws Xob Cable:

Insutrumention tus neeg & tag nrho cov screen xo hlau hlau tshuab ua paug / swa khub yog siv hauv cov ntaub ntawv kev ua lag luam thiab kev tswj cov txheej txheem. Haum rau kev ruaj ntseg sib sau hauv cov chaw noo thiab qhib qhov chaw. Lub tshuab hluav taws xob hluav taws xob tiv thaiv cov chaw muaj kev cuam tshuam sab nraud.

1. Desing:

LSZH (tsawg pa taws lub zog ntawm Halogen) Cable Cable muaj cov khub tooj liab lossis dawb, dawb thiab liab twisted triples nrog cov lej txuas ntxiv.

2. Voltage ntsuam xyuas:

Ntsuas hluav taws xob max. 300v AC; Nominal voltage ac / dC 110 / 150V, kev sim voltage hauv cov txheej txheem spark xeem - 4500v thiab ac withstand

Cov ntaub ntawv ntsuas - 1500v, cov ntaub ntawv cov ntaub ntawv 0.5 hli 1.5 hli

3.Maximag Caportance

Tus neeg xyuas coj los saib xyuas 145pf / m 200PF / M 200PF / M, CEAMOR rau SCREEN 240PF / M, siab tshaj plaws ntawm tus neeg saib xyuas @ 20 C 3.4ω / km,

Rwb thaiv tsev tsis kam @ 20mω / km 140mω / km, hla kev ua tib zoo sib tham ntawm khub @ 1kHz 300ω 150ω

Inductance @ 1kHz 1.00mh / km 0.95mh / km, l / r recio @ 1kHz 13.7hzh / ω

4. Pauv rau qhov kub

Yam tsawg kawg nkaus ua haujlwm ntsuas kub -25 ° C, 75 ° C, 90 ° C, tsawg kawg nkaus li luv hluav taws xob 160 ° C (rau 5 sec)

5. Dab tsi yog khoov hluav taws xob:

Cov hauv qab no tsawg kawg yog khoov hluav taws xob hluav taws xob yuav tsum tau pom kom ntseeg tau kev ntseeg siab ua haujlwm

Unarmoured: 9 x cab sab nraud ntawm lub taub (thaum installation) 6 x cable txheej ntawm lub taub (tom qab teeb tsa)

ArmORSED: 18 x cable txheej uas txoj kab uas hla (lub sijhawm installation) 12 x cable txheej txheej (tom qab teeb tsa)

6.Tensile lub zog

Cable feem ntau rub tawm nruj (kwv yees) yog txwv rau 65-70 n / mm² ntawm tag nrho cov chaw hla ntawm thaj chaw ntawm lub nroog ntawm lub nroog ntawm lub nroog ntawm cov cheeb tsam ofconductor.

7.example:

Lub 1.5 Tag nrho cov crossal thaj tsam 3x 2 × 1.5 = 9 hli 9mm² x 70nmm² = 630n (0.63kn)

Rau rub los ntawm armor, rub tawm nro yuav tsum tau txwv rau 130 n / mm² ntawm tag nrho cov cross-seem ntawm steel hlau.
