Overhead line coupling fitting

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.

The OPGW Hardware Fittings are instrument used for surge protection of communication and transmission lines. It replaces the earlier PLCC (using waves as the transport medium) with an optical signal which is faster and distortion free. a professional manufacturer of OPGW & ADSS cable prefabricated parts with many years of experience. With a factory area of 26,593 square meters, we can produce and transport about 1,000,000 PCS of prefabricated parts (OPGW & ADSS) per year. We have world class certificates such as ISO 9001:2015 certification and are trusted by several companies. More than 15 professional R&D engineers and timely technical support ensure to provide high quality and competitively priced solutions to make customers more profitable in this industry.

The unique design of the lightweight HuaNeng Fitting mechanical suspension supports spans of optical ground wire (OPGW) cables through a wide range of line angle variations. HuaNeng Fitting's mechanical suspension is easy to install while supporting vertical, lateral, and longitudinal unbalanced loads and angular tension without damaging cable strands or affecting fiber performance. Separate bolts Composition inner twisted wire, Outer twisted wire, Rubber block and cast aluminum shell. Uses To play a supportive role, the optical fiber composite overhead ground wire (OPGW) are hung on a straight line on the tower.

ADSS fittings 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 fitting 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. About us design and construction makes ADSS mounting and threading accessories inherently rugged and rigid, and compliant with various international and TEC codes. These fittings are available in a variety of designs to meet the requirements of different pole/tower spans and different types of pole/tower members.
