The preformed top tie is mainly used for binding between insulators and overhead insulated wires and bare wires in overhead lines of 10 kV and below.
The power distribution top tie can be used to fix bare or insulated wires in the top grooves of pin insulators and post insulators of the power distribution system. The binding wire can fix the wire in the top groove and the side groove.
According to different binding positions and methods, it can be divided into:
1. top tie preformed
2. Single side tie preformed
3. Double side tie preformed
4. Double top tie line

Technical characteristics
◆High strength; tensile strength is 8-18 times that of aluminum binding wire and 3 times that of copper binding wire;
◆High grip strength; low can easily exceed 350kg, so the disconnection can be limited within one span; and the load can be reduced before the pole and the structure are damaged;
◆High pull-off strength; sufficient material strength and ring structure provide the necessary resistance to side pull and uplift, thereby effectively preventing the wire from leaving the insulator groove;
◆It has good resilience; under additional loads such as tree impact, wire dancing and ice removal, due to its good resilience, the wire can maintain normal sag and tension;
◆Radio interference level is low; does not exceed the interference level of insulators;
◆Easy installation and improved construction efficiency; the power distribution tying line can be installed with bare hands in 30 seconds, and the installation time with a live insulating pole will not exceed 3 minutes; while the traditional manual tying needs at least 10 minutes.
