The disadvantage of corona discharge is that it will cause targeted damage and performance loss to equipment in different scenarios. In high-voltage transmission lines, the tip structure of wire joints, insulators, fittings and other parts can easily cause corona. The local high temperature and acidic substances generated by the discharge will accelerate the aging and cracking of the wire insulation layer, resulting in the risk of leakage in advance of the line. In the scenarios of communication transmission and optical cable laying, the hazards of corona discharge are more specific. The high-frequency signals transmitted by the communication line are susceptible to interference by electromagnetic radiation generated by the corona, resulting in signal attenuation, increased noise, and even call interruption or data transmission errors in severe cases. Although the optical cable does not transmit current, if the outer sheath is exposed to the corona environment for a long time, it will also be eroded by ozone and ultraviolet radiation generated by the discharge, cracking and aging will occur, thereby affecting the mechanical strength and transmission stability of the internal optical fiber.
Corona discharge can also cause cross-scenario health and compliance risks, posing multiple pressures on buyers. Whether it is in the inspection of transmission lines, the maintenance of communication base stations, or the laying of optical cables, if the concentration of ozone generated by the discharge exceeds 0.1mg/m3, it will irritate the respiratory tract of operation and maintenance personnel, and long-term exposure may induce chronic bronchitis. Although the high-frequency electromagnetic radiation generated by corona discharge is low in intensity in a single scene, superimposed exposure in multiple scenes can interfere with the human nervous system, resulting in inattention and fatigue. In the European and American markets, the "EU Workplace Health and Safety Directive" and "U.S. Occupational Safety and Health Act" have strict limits on ozone concentration and electromagnetic radiation in different scenarios. If the purchased equipment exceeds the standard due to corona discharge, the company not only needs to bear the cost of equipment rectification, but may also face fines of up to millions of euros, and even be suspended from project operations.
However, it is very simple to solve these shortcomings caused by corona discharge. Our vibration damper corona ring is your best choice. Vibration damper corona ring is made of high-strength alloy material, and the surface is treated with a special insulating coating, which can not only optimize the electric field distribution on the surface of the equipment, reduce the corona discharge intensity of the transmission line, but also reduce the electromagnetic radiation interference of the communication line, and reduce the aging rate of the outer sheath of the optical cable. And our vibration damper corona ring is easy to install, does not require disassembly of equipment, and can shorten the time of power outages and communication outages. At present, our vibration damper corona ring has served more than 30 multinational projects such as European power grid upgrade projects, Southeast Asian communication base station construction, and Australian optical cable laying projects, and has won long-term orders from a number of companies. For B-terminal buyers, choosing our vibration damper corona ring can not only solve the pain points of corona discharge, but also ensure the long-term stability of transmission, communication, and optical cable systems and reduce operating costs.
