1. The use of tube strands can make economical and convenient cables such as stainless steel central tube fiber optic devices or wire strands. The wire of the tube strand is released from the inner wire frame, so the strand of the wire still uses the stranding method of the ordinary tube strand. The core wire is sent out from the outer core wire frame and will not rotate under the action, so the core wire is less bent and worn, and the core wire runs completely straight. Prevent twisting of the core wire.
2. In order to avoid mutual contact before the core wire and the steel wire are kinked, Guanci passes the steel wire through the kink on the side of the core wire frame. That is to say, it fully combines the characteristics of the tube and the bow strand, and can withstand the use of economical and practical tube strands to twist cables such as stainless steel central tube fiber optic devices or steel strands.
