Medium-Voltage And High-Voltage Power Line Metal Oxide Arresters
Our Power Line Lightning Arrester offers merchants a high-quality, reliable, and cost-effective solution for protecting electrical infrastructure against lightning strikes. With our five-year warranty, easy installation, and superior design, our lightning arrester can provide consistent protection for years to come.
Power line lightning arrester for MV and HV type
● Type: MV and HV
● Application: Power line lightning arrester for MV and HV type
● MATERIAL: Polymer housing
● Color: Grey
● High quality MOV discs/ blocks
● 100% routine tested
● KEMA, CEPRI, XIHARI test report and ISO 9001 quality certification
● Comply with GB, IEC, IEEE and other standards
Installation of power line lightning arresters at recommended locations along the line in accordance with our line simulation ensures anhanced overvoltage protection. Selecting the optimum line lightning arresters, especially in terms of their quantity and installation locations, significantly improves the reliability of the overall line system and the quality of power that it supplies
Beneficial applications
• Improve lightning protection performance
• Reduce outages caused by poor grounding and high lightning activity
• Reduce double-circuit outage rates / protect underbuild distribution lines
• Provide switching surge control - structural optimization and lower clearances
• Improve safety - prevents personal injuries and damage to equipment
• For line upgrading and compaction - reduced insulation levels
• For live work on the line -temporarily reduce minimum approach distance
• Achieve lower installation costs and losses in line system (outages)
Two different power line lightning arrester designs are available
1. Non-Gapped Line Arrester (NGLA)
Non-gapped line surge arresters (NGLA) offer a high degree of mounting flexibility and operational reliability. Depending on the tower design and the arrangement of insulators and lines, these arresters can either be installed directly on the insulators or on the tower. NGLAs limit overvoltages to value levels below the insulator withstand voltage.
Advantages of NGLA
• Most flexible solution (installation at conductor, tower, insulator etc.)
• A disconnector is installed in series that disconnects the arrester in case of thermal overload
This ensures further operation of the overhead line until a replacement can be scheduled
• Offer a very high level of protection against lightning and switching overvoltages thanks to their high energy absorption capacity
• Designed and tested to comply with the latest IEC 60099-4 standard
2. Externally Gapped Line Arrester (EGLA)
Uchi Electric EGLA line surge arresters have an external spark gap placed in series that galvanically isolates the active part of the line surge arrester from the line voltage under normal conditions.
In case of lightning, the spark gap flashes over and the arrester limits the ground fault current from several kA to a few amperes, and extinguishes the arc within 10 ms such that no circuit breaker operation at both line ends is needed, i.e. no reclosing operation.
Advantages of EGLA
• No leakage current, since the series gap disconnects the arrester part of the EGLA - metal-oxide varistor (MOV) blocks - from the system voltage under normal service conditions
• Lower arrester rated voltage required
• No disconnector and no ground lead are needed
• Suitable for multiple-circuit towers with short clearances - the highly compact design of the EGLA and the absence of a ground lead allow installation and lightning protection even on towers with very small cross-arm clearances
• Better suited for live installation
• Complete EGLA solutions with polymer insulators also available
