8字型层绞式光缆(GYTC8A)
Figure 8 Cable
产品描述 Description
GVTC8A光维的结构是将250μm光纤套入高模量材料制成的榴套管中，松套管内填充防水化合物。缆芯的中心是一根金属加强芯，松套管(和填充绳)围绕中心加强芯绞合成紧凑和圆形的缆芯。缆芯用一层涂塑铝带(APL)纵包后，和钢丝绞线集成一个8字型的聚乙烯护套内。
本公司还可以提供Y护套或S护套的8字形光缆GYTCBY、GYTC8S,等，此类产品多应用于自承式架空敷设。
The ftbers 250 u m,are posttoned in a loose tube made of a high moculus plastte.The tubers are flled with a water-resistant filingcompound.A steel wire locates in the center of core as a metallic strength member.The tubes(and fillers)are stranded around thestrength member into a compact and clrclar cable core.Atter an Aluminum Polyethylene Laminate (APL)moisture barfier is appliedaround the cable core this part of cable accompanied with the stranded wires as the supporting part are completed with a polyethylene (PE)sheath to be figure 8 structure.
Figuro 8 cable GYTC8Y,GYTC8S are also available on request.This type of cable is speclically applled for soll-supporting aerial instalationl
