Cable description
GYFTA
ADSS cable is used for high-voltage transmission lines, using the power system transmission tower rod, the
whole cable is non-metallic medium, self-bearing suspension on the power tower electric field intensity of
the smallest position. It is applicable to the established high-voltage transmission lines, because of its
savings in comprehensive investment, reduce the artificial damage of optical cable, high security, no
electromagnetic/strong electric interference, long span, deeply favored by the majority of power system
users. It is widely used in the communication construction of power system urban network reconstruction
and rural network reconstruction.
