RF cable hi high-frequency signal transmission atana medium pawimawh tak a ni a, an molding process hian an electrical performance leh mechanical reliability chu direct-in a nghawng a ni. Molding process hian signal integrity leh application environment complex tak takah adaptability a awm theih nan material property, structural design, leh manufacturing precision te a balance tur a ni.
Moulding atan hian material thlan leh pretreatment hi a pawimawh ber a ni. RF cable-ah hian a tlangpuiin inner conductor (copper wire emaw silver-plated copper wire ang chi), insulation layer (polytetrafluoroethylene (PTFE) emaw polyethylene (PE ang chi), shielding layer (braided copper mesh emaw aluminum foil ang chi), leh pawn lam jacket (PVC emaw polyurethane ang chi) te a awm thin.Insulation material hian low a nei tur a ni dielectric constant leh loss tangent a ni signal attenuation tih tlem a, shielding layer erawh chuan electromagnetic interference tihtawp nan coverage sang tak a neih a ngai thung. Pretreatment stage chhung hian conductor chu tihfai leh annealed a ngai a, chu chuan stress tihziaawmna leh ductility tihchangtlun a ngai a, chu chuan a hnua moulding neih hunah dimensional stability a tichiang a ni.
Extrusion leh insulation molding te hi a pawimawh ber a ni. Insulation layer hi conductor chung lamah precision extruder hmangin an hnawih a. Nitrogen assist emaw high-temperature mold emaw hmangin PTFE ang chi material te expansion coefficient control a ni a, chu chuan bubble leh eccentricity a veng thei a ni. Multi-layer structure tan chuan insulation leh shielding te hi extrusion process hrang hrang hmangin layer khat hnu laminated a ni a, online capacitance tester hmangin thickness uniformity chu real time-ah enfiah a ni.
Braid leh shield inzawmkhawm hian anti-interference theihna a nghawng nghal vek a ni. Shielding layer hi a tlangpuiin high-speed braiding machine hmanga braid a ni a, copper emaw tinned copper wire emaw chu angle bik (eg, 45℃-60 degree)-ah wrapping a ni. Faraday cage effect siam tur chuan density 90% aia tam a ni tur a ni. High-end cable thenkhat chu aluminum-plastic composite tape longitudinal wrapping hmangin a tichak zual hle. He step hian conductor a inthlak emaw insulation a chhiat loh nan tension control khauh tak a mamawh a ni.
Outer sheath molding leh post-processing hian venhimna hnuhnung ber chu a zo ta a ni. Sheath material chu extruder-ah temperature sang takah an melt a, chu chu shielding layer-ah an hnawih a ni. Chumi hnuah chuan cooling water tank kal tlangin a set nghal vat a, roundness a vawng reng bawk. Special application (aerospace ang chi) atan chuan temperature leh abrasion resistance tihchangtlun nan radiation cross-linking process dang a ngai thei bawk. Cable siam zawh tawh chu industry standard zawm a nih theih nan high-frequency testing (VSWR vector network analysis ang chi) leh mechanical performance verification (flex life testing ang chi) a paltlang a ni.
RF cable siam dan hi materials science, mechanical control leh electromagnetic theory inzawmna hmunah a awm a ni. A level of sophistication hian communication system rintlakzia a hril nghal vek a ni. 5G leh satellite communications hmasawnna avang hian ultra-low-loss, highly flexible cables mamawhna hian process innovation a tichak chhunzawm zel dawn a ni.
