BMC SB 25-60 Series Insulators: The Smart Choice for Power Systems

The SB series standoff insulators are pivotal in cutting-edge energy sectors, including battery packs for new-energy vehicles, energy storage systems, and photovoltaic inverters.
In new-energy vehicle battery packs, these insulators ensure the safe isolation of circuits, effectively preventing current leakage and maintaining the stable operation of the entire battery system.
Within energy storage systems, the SB series busbar insulators provide robust support, enabling stable performance in complex electrical environments.
As core components of photovoltaic inverters, which convert direct current into alternating current, the SB series low-to-medium voltage insulators effectively isolate circuits, prevent current interference and leakage, and withstand high-temperature conditions. This ensures efficient conversion and stable operation of photovoltaic inverters.
Recognizing the diverse and challenging installation environments faced by our customers—such as outdoor settings with high temperatures and humidity, like photovoltaic power stations in desert regions—we understand the critical need for insulators that offer exceptional high-temperature resistance, moisture resistance, and durability.
To meet these stringent requirements, a comprehensive and scientific quality inspection system has been established. When customers have concerns or requirements regarding the reliability of our insulators, a series of targeted reliability tests tailored to specific needs are conducted.
Key Reliability Tests Include:
  • Long-Term Operation Tests in Simulated High-Temperature Environments: By placing the insulators in a high-temperature test chamber with varying temperature gradients and durations, performance indicators such as insulation resistance and dielectric constant are rigorously monitored.
  • Simulated Humidity Environment Tests: Utilizing professional humidity test equipment, environmental humidity levels are controlled to observe the surface conditions and electrical performance of the insulators.
  • Durability Tests: Simulating current shocks and mechanical vibrations encountered during actual use, evaluating the performance stability of the insulators over extended periods.
Upon completion of these tests, detailed and accurate reliability test reports are provided, ensuring insulators meet the highest standards of performance and durability.
