Product Discription of ADSS Fiber Cable 12 Core B1.3:
The fiber is made of quartz glass (silicon dioxide), which is generally divided into three layers: the core is a 9 micron high refractive index glass core, the second layer is a 125 micron low refractive index cladding, and the outer layer is a protective resin coating with a diameter of 245 micron.
This product has excellent mechanical stability and environmental performance; there is no metallic material in the ADSS cable, it has excellent performances such as resistance to lightning stroke and electromagnetic interference. This ADSS cable is light weight, high tensile strength and lng-span erection crossing the river and canyons.This product has produced in enormous quantities, it has mature and stable production engineering, strict requirements of quality control, scheduled validation product performance to ensure the product reliability.
This specification is applicable to high voltage transmission system, also applies to long-span erection of ADSS cable communication lines in high-elevation thunderstrom area. This standard stipulates ADSS cable product classifications, type, model, structure, cable fiber technical parameters and text method, and the requirements of packing and storage.
This specification covers the classification,type,construction,technical parameter,packaging and storage requirements.
