Product Description

BMC SB 25-60 Series Insulators: Introduction

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.
New-Energy Vehicle Battery Packs
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.
Energy Storage Systems
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 in practical applications—such as outdoor settings with high temperatures and humidity, like photovoltaic power stations in desert regions—there is a critical need for insulators that offer exceptional high-temperature resistance, moisture resistance, and durability.
Comprehensive Quality Inspection System
To meet these stringent requirements, a comprehensive and scientific quality inspection system is utilized. Targeted reliability tests tailored to specific operational needs 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 closely monitored under high-temperature conditions.
  • 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 under different humidity conditions.
  • Durability Tests: Simulating current shocks and mechanical vibrations encountered during actual use, the performance stability of the insulators over extended periods is rigorously evaluated.
Upon completion of these tests, detailed and accurate reliability test reports are generated, ensuring insulators meet the highest standards of performance and durability.
