Ncua clamps feem ntau yog siv rau cov kab hluav taws xob overhead.Cov hlau raug tshem tawm los ntawm cov insulators los yog xob laim hluav taws xob raug tshem tawm los ntawm cov ncej yees los ntawm kev sib txuas fittings.

Cov tsoos malleable cam khwb cia hlau clamps muaj qhov tsis zoo ntawm qhov loj hysteresis poob, qhov loj qhov tam sim no poob, thiab cov khoom loj.Aluminium alloy clamp muaj qhov zoo ntawm qhov tsis tshua muaj me me hysteresis poob thiab eddy tam sim no poob, lub teeb yuag, thiab kev tsim kho yooj yim.Nws ua tau raws li cov kev xav tau ntawm kev txuag hluav taws xob thiab kev txo qis hauv lub teb chaws fais fab kev hloov pauv thiab kev tsim kho.

Thaum lub ncua kev kawm ntawv clamp yog siv rau txhuas stranded hlau thiab steel tub ntxhais txhuas stranded hlau, nws yuav muab qhwv nrog txhuas sheathing los yog tiv thaiv hlau los tiv thaiv cov hlau.Qhov siv tau sab nraud ntawm cov hlau muaj xws li wrappings.

Cov khoom siv txuag hluav taws xob tsim los ntawm peb lub tuam txhab tau dhau los ntawm Kev Tshawb Fawb Kev Tshawb Fawb thiab Kev Tshawb Fawb Kev Tshawb Fawb ntawm Ministry of Electric Fais Fab Kev Lag Luam, ua tau raws li qhov yuav tsum tau ua ntawm GB2314 thiab cov qauv tsim, thiab tau dhau lub teb chaws kev txuag hluav taws xob.

Qhov feem pua ​​​​ntawm ncua kev kawm ntawv clamp gripping quab yuam rau ntsuas tensile quab yuam ntawm hlau:

Hlau Class		Hlau Structure (Aluminium Ratio)	Feem pua
	ACSR (Steel core aluminium stranded hlau)	> 1.7	12
		4.0-4.5	18
		5.0-6.5	20
		7.0-8.0 Nws	22
		11.0-20.20 Nws	24
	Hlau stranded hlau	Qhov kawg lub zog 1176-1274	14
	Aluminium stranded hlau		30
