AL-covered Stainless Steel Tube OPGW

Optical fibers are placed in a hermetically sealed stainless steel tube covered with aluminum layer. The central aluminum-clad stainless steel tube is surrounded by single layer or double layer metal wires. Good anti-corrosion performance, suitable for highly corrosive environment, no need to use anti-corrosion grease.

Characteristics:

Al-covered stainless steel tube design increases the cross section ofAL, to reach a better short-circuit current and lightning resistance performance;
Good anti-corrosion performance;well suited for highly corrosive environments no need to use anti-corrosion grease;
Applied to the transmission line which requires small diameter and largeshort-circuit current;
Offers greater crush and mechanical protection to the fibers from environmental effects.

Standards：

IEC 60794-4-10	Aerial optical cables along electrical power lines – Family specification for OPGW
IEEE1138-2009	IEEE Standard for testing and performance for optical ground wire (OPGW) for use on electric utility power lines
