Sciath braidáilte sraithe singil: Is é an príomh-struchtúr ciseal de mhogalra braidithe, agus tá clúdach an mhogalra braidithe thart ar 70 faoin gcéad -95 faoin gcéad . Is é -50dB an cumas sciath, a úsáidtear go príomha i líonra sreangaithe 1GHz. Go ginearálta ní mholtar cábla comhaiseach sciath aon-chiseal braidáilte le húsáid i dtástáil RF. Is féidir le léamha méadar cumhachta neamhchothromaithe a bheith mar thoradh ar a struchtúr sciath aonair mar gheall ar sceitheadh leictreamaighnéadach. Má tá gá le tástáil RF, is fearr sciath nó sciath dhá chiseal a úsáid. Cábla comhaiseach níos cumasaí.
Double-layer braided shield: This type of coaxial cable shield is composed of two layers of braid, and the shielding strength is -75dB-85dB, usually up to 6GHz in application. Double shielded coaxial cables are widely used in RF testing.
Sciath trí chiseal: Cuir ciseal eile de chiseal sciath miotail scragall alúmanaim idir an dá shraith de sciath braidáilte, is é sin, sciath dúbailte-ciseal (foirceannadh móide braiding), cuirtear an ciseal istigh le créachta. téip copar, agus tá an ciseal seachtrach braided. Is é 100 faoin gcéad clúdach an struchtúir sciath, is féidir le feidhmíocht sciath na dtrí chiseal cábla comhaiseach sciath a bhaint amach -90-100dB. Is struchtúir sciath trí chiseal iad an chuid is mó de na cáblaí comhaiseacha a úsáidtear in iarratais tástála EMC agus micreathonnta.
Solid shielding: The shielding of the coaxial cable is made of aluminum tube or copper tube, and the coverage of the shielding structure reaches 100 percent . For example, semi-steel coaxial cables are all solid shielded coaxial cables, which are mainly used for internal interconnection of equipment. It can also be used in passive intermodulation measurement systems with very strict shielding requirements without considering the direct mutual interference of cables.
