產(chǎn)品特點(diǎn)及用途
Properties and purpose of produc
本產(chǎn)品具有低電容和低電感，并具有根好的屏蔽性能和抗干擾性能，因而防爆性能優(yōu)于一般計(jì)算機(jī)電纜和控纜，它適用于有防爆要求場合的集散系統(tǒng)和自動(dòng)化檢測控制系統(tǒng)等電路中作傳輸線。
This category of products boasting low capacitance,lowinductance,excellent shielding properties and distur-bancereisting property,so it its explosion protection performance isbetter than ordinary type computer cable and control cable.Thiscategory of products,as transmission cable,is applicable fordistributed control system and automatic control system.
