● replace the existing ground wire, and transform the power of communication lines
● the new overhead power line shall be constructed along with the ground wire.
● provide the best protection for transmission unit of stainless steel fiber.
● conduct the short-circuit current and provide protection against lightning

● cable’s diameter is small, the weight is light, and the additional load on the tower is low.
● stainless steel wire’s diameter is greater than the diameter of aluminum-coated steel wire and aluminum alloy wire
● stainless steel fiber units located in the center of twist level, so it can be protected better.
● get the maximize fiber excess length in the smallest steel tube 
● the single armored cable has lower anti-twist , lower anti-side pressure and lower anti-stretch ability 
● operating temperature: -40 ℃ ~ +80 ℃
