電纜層結(jié)構(gòu)

心導體:中心導體是純銅線或銅包鋁、銅包鋼。

中心導體的粘合劑:一種專利產(chǎn)品聚合物粘合劑。該種粘合劑能確保將電介質(zhì)與中心導體粘結(jié)在一起,杜絕水分和潮氣的入侵。

電介質(zhì)(絕緣體)泡沫:該種電介質(zhì)泡沫是一種氮氣膨化、封閉的聚乙烯泡沫。

第一屏蔽層:由延壓成薄片的鋁和聚乙烯組成的屏蔽帶,給該電介質(zhì)提供100%的覆蓋率。這個屏蔽層同軸于中心導體與電介質(zhì)并且屏蔽帶邊至少有18%的交疊,使得電介質(zhì)被緊緊罩住,使其具有長期穩(wěn)定的最小的信號泄露。

第二屏蔽層:是用直徑位0.120.15mm的鋁鎂合金絲(鍍錫銅線)編織而成,既提供了一個輔助的屏蔽層,又改進了機械強度。

第三屏蔽層:位在某些高頻干擾環(huán)境中,提供一個特殊的屏蔽需要。其組成為一個未粘合的鋁箔--聚乙烯--鋁箔帶。

第四屏蔽層:直徑為0.120.15mm的鋁鎂合金絲(鍍錫銅線)編織而成。

防潮增補膠

護套層:PEPVC護套料擠塑在編織層上而成。

電纜吊掛索:這種電纜是單或多根絞線鍍鋅鋼絲,外面包裹護套,并且用一個易于分離的連接層附著在電纜護套上。

The cable structure

Center conductor: The conductor is the center line of pure copper or copper clad Aluminum,

copper clad steel.

     The center conductor binder: a patented polymer adhesive products. The kind of adhesive

can ensure that the center conductor and dielectric bonded together, put an end to water and

moisture intrusion.

     Dielectric (insulation) foam: that the dielectric is a bubble of nitrogen extruded,

closed polyethylene foam.

     The first shield: the extension by the pressure into a sheet of aluminum and composed

of polyethylene shielding belt, the dielectric to provide 100 percent coverage. The coaxial

shielding layer in the center conductor and dielectric shield and side with at least 18%

overlap, making dielectric has been closely hooded, with its long-term stability of the

smallest signal leakage.

     The second shield: with a diameter of 0.12-0.15mm or the aluminum-magnesium alloy wire

(copper-tin) from weaving, both to provide a supportive shield, and improved mechanical

strength.

     The third layer shielding: in some high-frequency interference in the environment, with

a special need for shielding. As a component of its non-bonded aluminum foil - polyethylene

- with aluminum foil.

     Fourth shield: a diameter of 0.12 or 0.15mm of aluminum-magnesium alloy wire (copper-

tin) from weaving.

     The addition of moisture-proof plastic

     Sheath layer: PE or PVC sheathing layer extrusion in weaving together.

     Cables hanging cable: This cable is a single root or galvanized steel wire, wrapped the outside jacket, and an easy-to-separation connection layers attached In the cable jacket on.
