Method does not meet the technical issues of code requirement.
2, the interim traction connector of steel strand wires in the present invention is simple in structure, and stress is clear, ensures that steel twists by intermediate plate
Line traction is safe and reliable.
3, the interim traction connector cost of manufacture of steel strand wires in the present invention is cheap, with good economic efficiency and practical
Property.
4, install that a interim traction connector only needs 30 seconds in application method in the present invention, installation and dismounting
Process is convenient and efficient, and work efficiency is high, and the interim traction connector of steel strand wires is repeated and is used in turn.
5, by field demonstration, the interim traction connector of steel strand wires draws installation for steel strand wires in the present invention
It is solid and reliable, substantially increase steel strand wires installation efficiency.
