电缆层结构
中心导体:中心导体是纯铜线或铜包铝、铜包钢。
中心导体的粘合剂:一种专利产品聚合物粘合剂。该种粘合剂能确保将电介质与中心导体粘结在一起,杜绝水分和潮气的入侵。
电介质(绝缘体)泡沫:该种电介质泡沫是一种氮气膨化、封闭的聚乙烯泡沫。
第一屏蔽层:由延压成薄片的铝和聚乙烯组成的屏蔽带,给该电介质提供100%的覆盖率。这个屏蔽层同轴于中心导体与电介质并且屏蔽带边至少有18%的交叠,使得电介质被紧紧罩住,使其具有长期稳定的最小的信号泄露。
第二屏蔽层:是用直径位0.12或0.15mm的铝镁合金丝(镀锡铜线)编织而成,既提供了一个辅助的屏蔽层,又改进了机械强度。
第三屏蔽层:位在某些高频干扰环境中,提供一个特殊的屏蔽需要。其组成为一个未粘合的铝箔--聚乙烯--铝箔带。
第四屏蔽层:直径为0.12或0.15mm的铝镁合金丝(镀锡铜线)编织而成。
防潮增补胶
护套层:用PE或PVC护套料挤塑在编织层上而成。
电缆吊挂索:这种电缆是单或多根绞线镀锌钢丝,外面包裹护套,并且用一个易于分离的连接层附着在电缆护套上。
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.
