Tube-type Big Sevent-polar Trolley Wire
1.Instruction
SL-HFP multi-polar(phase) tube-type trolley wire ,is a kind of safe, economical, reliable device that can be widely used. Meanwhile, it is a reliable alternative of cable shell-off coil cylinder. According to different structure, they can be divided into engineering plastic housing body and aluminum alloy housing body. From the 3rd term, the phase no. can be up to 16 terms. The housing can protect and support traveling rail of electricity-concentrator. The material of generating line is cold-drawing bronze.
