Overhead Line Lightning Protection (LOPT) for 35kV-6kV: Reliable Solution by China Suppliers & Factory

For overhead transmission lines operating at 35kV to 6kV, the installation of ZnO arrestors is common to prevent faults that can lead to tripping, line failures, and blackouts. Introducing the New Lightning Protection for Overhead Transmission Lines (LOPT), developed in China, which utilizes advanced near cathode effect technology alongside a multi-level short gap arc blowing and extinguishing system. This innovative solution overcomes the limitations of traditional ZnO arresters by employing a unique structural design that elongates the arc path, effectively suppressing overvoltage and ensuring efficient arc extinguishing.

As a leading supplier and factory of lightning protection solutions, LOPT offers numerous advantages, including enhanced safety, superior reliability, extended lifespan, and reduced maintenance requirements. It swiftly dissipates lightning energy, preventing breakage and tripping due to lightning strikes. Additionally, LOPT features a maintenance-free design with self-cleaning capabilities, making it the optimal choice for overhead transmission line protection.
