Aerial optical cables along electrical power lines-Family specification for ADSS(All Dielectric Self Supported) Optical cables.
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 andtext method,
and the requirements of packing and storage. This specification covers the classification,type,construction,technical parameter,packaging and storage requirements.
Description
This product has excellent mechanical stability and environmental performance; there is no metallic material in the ADSS cable,
it has excellentperformances 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.
