Spiral vibration dampers, also known as helical vibration dampers, are used in the overhead transmission line industry to reduce the vibrations that occur on the conductor due to wind or other external factors. These dampers are typically made of a spiral-shaped metallic wire, which is wrapped around the conductor at regular intervals along its length.
The application of spiral vibration dampers on transmission lines helps to reduce the amplitude of conductor vibrations, which in turn reduces the stress on the line, and prevents damage and failure of the transmission system. These dampers can be installed on overhead transmission lines for both AC and DC systems.
In addition to reducing conductor vibration, spiral vibration dampers also provide protection against galloping, which is a large-amplitude, low-frequency vibration that can occur when the wind blows across the conductor. This phenomenon can cause significant damage to the transmission line and is a major concern for power companies.

FYH Anti-corona Ring
Corona rings are annular metal rings that are fixed to the ends of bushings and insulator strings. They are also referred to as anti-corona rings. Corona rings are used to prevent corona discharges that occur in high voltage transmission lines.
Corona Ring
Corona rings are annular metal rings that are fixed to the ends of bushings and insulator strings. They are also referred to as anti-corona rings. Corona rings are used to prevent corona discharges that occur in high voltage transmission lines. Corona discharge or corona loss is a major problem in EHV transmission lines that cause power loss. One way to reduce corona discharge is to use corona rings.
How do corona rings work?
Corona discharge occurs when the electric field (potential gradient) on the surface of a conductor exceeds a critical value, called the critical destruction voltage. The value of the critical destruction voltage varies with atmospheric conditions. The value is about 30 kV/cm. The electric field is greatest where the curvature is sharpest. Therefore, corona discharges occur first at the points of greatest curvature - i.e., suspension points, corners and edges. Corona rings are installed at these points to prevent corona formation.
Corona rings are electrically connected to conductors around points where corona discharges may occur. Thus, due to its smooth circular shape, the corona ring distributes the electric field (or charge) over a wider area. As a result, it reduces the potential gradient below the critical damage value.
Manufacturers typically recommend installing aluminum corona rings at the conductor end of string insulators for lines above 230 kV and at both ends of insulators for 500 kV.

OPGW Hardware Fittings features.
1. The unique spiral cable clamp is designed to wrap securely around the cable. In this way, it not only disperses the stress on the connector cable points, but also protects the cable from damage in the event of rain, snow or wind.
2. Huaneng OPGW hardware fittings are easier to install. No special tools or guidance from an experienced engineer are required. Installation can be done manually.
3.Huaneng OPGW hardware fittings are highly resistant to corrosion. Most OPGW fittings are hot-dipped galvanised or made of aluminium. They do not rust easily.
ADSS Cable Accessories
ADSS cable accessories are used to secure ADSS cables to utility poles. The integration test between the fitting and the cable is approved according to the "NESC Heavy Duty" standard. The correct ADSS cable accessories is determined by the outside diameter of the cable and the length of the span to be covered.
What is an ADSS cable?
ADSS (All Dielectric Self-Supporting) cables are ideal for installation in power distribution and transmission environments, even when a live installation is required. As the name implies, no supports or slings are required, so a single installation is all that is needed, making ADSS an economical and simple way to.
