Description

All Dielectric Self-Supporting Optical Fiber Cable (ADSS) Application:


All Dielectric Self-Supporting Optical Fiber Cable (ADSS) is a kind of nonmetal optical cable made of dielectric material, it can bear the load and 

directly hang on the power tower, and it is mainly used for communication route in overhead high voltage transmission system.


All Dielectric Self-Supporting Optical Fiber Cable (ADSS) Contruction:


ADSS has the following features


♦ All insulated dielectric self-supporting aerial optical cable; no metal material; mainly used in power system.


♦ Large number of cores; light weight; can be erected on the same tower with the power line; saving resources.


♦ Construction and maintenance are convenient, power cut is not needed in most of the time.


♦ Aramid material with high tensile strength to bear the tension is used to prevent bird and gun shot.


♦ The thermal expansion coefficient is small, and the radian of optical cable line varies little as the temperature changes greatly.


♦ No lightning protection problem, it can be used in thunderstorm areas.
