Benefits Of JIS Type Countersunk Bolt Chain U-shaped Ring Pin

The JIS type countersunk bolt chain U-shaped ring pin (commonly used in power fittings as a connecting component of U-shaped hanging ring with countersunk bolt, pin chain, and ring pin) has the following core benefits in the connection of transmission lines and power fittings:
Reasonable force distribution and high load-bearing capacity
Uniform stress distribution: The bottom of the U-shaped hanging ring is an arc-shaped load-bearing surface, which, combined with the wire contact design of the "ring ring", can evenly transmit the tension of the wire, avoid local stress concentration, effectively absorb vibration and alternating stress, and improve the dynamic bearing capacity and service life of the fittings.
Distributed force distribution: In the double ring series installation mode, the tension of a single hanging ring is shared by two hanging rings, forming a "double safety" structure. Even if one link fails, the other link can still maintain basic force distribution, improving the safety of the overall connection.
Flexible connection and strong adaptability
Multi scenario adaptation: The U-shaped hanging ring can flexibly adapt to various hardware fittings (such as tension clamps, adjustment plates, hanging plates, etc.) through the bottom closed loop or double ear side holes, achieving "ring ring connection" or "double ear groove connection", and can adapt to multi-directional loads, effectively offsetting the torque generated by gentle wind vibration.
Size compatibility: JIS standards ensure precise matching of connection length, aperture, and bolt specifications, achieving "load matching+size compatibility" and ensuring connection reliability.
Anti loosening, high safety
Chain anti loosening: Used in conjunction with closed pins (such as ring pins), the closed-loop structure of the ring pin prevents it from rotating and falling off in the hole, and it is tightly attached to the hole through material elasticity, which can resist the slight wind vibration and strong wind dance on the tower, prevent bolt loosening, and avoid disconnection accidents caused by loosening.
Anti corona and anti scratch: The circular pin without a pointed end design effectively reduces the harm of corona discharge, while avoiding the risk of scratches on maintenance personnel caused by traditional open-end pin tips, improving the safety of high-altitude operations.
Easy installation and efficient operation and maintenance
High installation efficiency: The anti loosening design of the ring pin and other components makes installation convenient (can be completed with one hand, without the need for complex opening operations), reducing the difficulty and time of installation for high-altitude operations.
Convenient for inspection and acceptance: There are no visual blind spots, making it easy for unmanned aerial vehicle inspection image recognition and manual acceptance, which improves the operation and maintenance efficiency of the line.
