Iintambo ngokohlobo

Eguquguqukayo Frequency Drive Cable

Iintambo ze-Variable Frequency Drive (VFD) ziintambo zombane ezikhethekileyo eziyilelwe ukudibanisa iisistim ze-VFD kwiimotor, ziqinisekisa ukuhanjiswa kwamandla okusebenzayo nokuthembekileyo kunye nokuphazamiseka okuncinci kwe-electromagnetic (EMI). Ezi ntambo zenzelwe ukujongana neempawu ze-high-frequency kunye ne-voltage spikes eziveliswa yi-VFDs, ezilawula isantya kunye ne-torque yee-AC motors. Iintambo ze-VFD zibalulekile ekugcineni ukusebenza kunye nokuphila ixesha elide kokubini i-drive kunye nemoto, ukunciphisa ingxolo yombane, kunye nokuphucula ukusebenza kakuhle kwenkqubo.

Iintambo ze-VFD ziyaziwa ngokwakhiwa kwazo olomeleleyo, ukhuseleko oluphezulu lwe-EMI, kunye nokuxhathisa okuphezulu kwe-thermal. Zingamacandelo abalulekileyo kwi-automation ye-industrial automation kunye nezicelo zokulawula iimoto, ziqinisekisa ukusebenza okuzinzile kunye nokuphazamiseka.
