In recent years, with the strengthening of my country's economic strength and the significant improvement of people's living standards, the power load has continued to rise, and the people's requirements for power quality and power outage time have become increasingly strict. The necessary process for inspection, at present, rubber-plastic copper or aluminum binding wires with a width of 2.0~2.5mm are used for fixed binding in China. From the perspective of long-term operation, there are many problems in this process. How to solve these problems is a difficult problem in front of live working technicians. There are mainly the following problems in the fixed binding process of rubber-plastic copper or aluminum binding wires:

1. The rubber-plastic copper or aluminum binding wire has a circular cross-section. When fixing and binding the porcelain bottle, due to the convex contact, the contact area is small, the friction coefficient is small, and the fixing is not firm.

2. Rubber-plastic copper or aluminum-bound wires age quickly in the natural environment. During long-term operation, surface friction occurs due to wire vibration, which damages the outer insulation layer of insulated wires, causes discharge, and generates heat that burns and breaks the porcelain bottle due to discharge. If not in time It is found that the ground short circuit fault has occurred.

In order to solve this problem, the existing technology uses the anti-corrosion properties of stainless steel to replace rubber-plastic copper or aluminum binding wires. For example, the utility model patent named "Stainless Steel Cable Tie" with Chinese Patent No. 200720195240.7 provides a stainless steel cable tie. Belongs to strapping. It includes a belt body, a buckle, and a steel ball installed in the buckle. The lock buckle has a belt inlet, a belt outlet, and a steel ball raceway. There is an empty groove on the ball raceway. There are convex points on the inner wall of the bending surface of the belt body. After the belt body described in this solution is inserted from its belt inlet, it is only pressed by steel balls at last. Since the belt body inserted into the buckle and the belt body originally arranged in the buckle are in contact with smooth surfaces, The friction between them is very small, and they will slide during long-term use, so the binding is not particularly firm, and accidents may occur in some special cases.
