Ocingweni lwe-poly wire, sasebenzisa insimbi engagqwali engu- #304A ukwenza i-poly wire, intambo yensimbi engenasici yocingo lwe-poly kufanele ibe nokusebenza okuqinile kokugqwala kanye nokuhamba kahle, ngakho-ke izinga locingo noma i-poly wire yethu: GB4240-2007 , okuqukethwe kwe-nickel okungengaphansi kuka-8%, okuqukethwe kwe-chromium okungengaphansi kuka-15%, ngaphandle kwalokho, intambo yensimbi engagqwali yocingo lwe-poly izogqwala kalula futhi ibe ne-conductivity ephansi. ngaphandle kwalokho, intambo yensimbi engagqwali yocingo lwe-poly kumele kube inqubo ye-hydride (inqubo yentukuthelo), ngaphandle kwalokho, ucingo lwensimbi engagqwali luzogoba kalula.

i-diameter yensimbi engagqwali etholakalayo ye-poly wire kanje:

Φ0.16mm intambo yensimbi engagqwali, ngokuvamile ithathelwa indawo Φ0.15mm
Ku-Φ0.15mm, ukubekezelela ngu-0.005mm, okungukuthi Φ0.145~Φ0.155mm

Φ0.20mm intambo yensimbi engagqwali, ukubekezelela kungu-0.01mm, okungukuthi Φ0.19mm~Φ0.21mm,

Φ0.40mm insimbi engagqwali, indawo yayo Φ0.35mm, Φ0.37mm

Φ0.38mm intambo yensimbi engagqwali, lena ayitholakali, ngokuvamile ithathelwa indawo Φ0.32mm
