Product Description

BMC SB 14-20 Series Insulators: The Smart Choice for Power Systems Introduction

In terms of application fields, the SB series standoff insulators are mainly applied in cutting-edge areas such as battery packs of new-energy vehicles, energy storage systems, and photovoltaic inverters. In the battery packs of new-energy vehicles, they play a crucial role in ensuring the safe isolation of circuits. The SB series electrical insulators can effectively prevent current leakage, thus guaranteeing the stable operation of the entire battery system. With their excellent insulation performance, the SB series busbar insulators can operate stably in complex electrical environments and provide solid support for the normal operation of energy storage systems. As the core equipment of solar power generation systems, photovoltaic inverters need to convert direct current into alternating current, which generates a large amount of current and heat during the process. The SB series low-medium voltage insulators can effectively isolate circuits, prevent current interference and leakage, and at the same time withstand a certain high-temperature environment, ensuring the efficient conversion and stable operation of photovoltaic inverters.

However, different customers face a variety of complex installation environments when using these devices. Some customers may install the devices in outdoor environments with high temperature and high humidity, such as photovoltaic power stations in desert areas, where the temperature is extremely high during the day and the air may also contain a certain amount of sand and moisture. Customers have extremely high expectations for the high-temperature resistance, moisture resistance, and durability of the insulators. They hope that the insulators will not age or be damaged in extreme environments.

To meet these strict requirements of customers, a comprehensive and scientific quality inspection system has been established. When questions or requirements arise regarding the reliability of the insulators, a series of targeted reliability tests are conducted according to specific needs. These tests include long-term operation tests in simulated high-temperature environments. By placing the insulators in a high-temperature test chamber and setting different temperature gradients and time periods, changes in performance indicators such as insulation resistance and dielectric constant of the insulators under high-temperature conditions are detected. There are also tests in simulated humid environments, where professional humidity test equipment is used to control environmental humidity and observe surface conditions and electrical performance under different humidity conditions. At the same time, durability tests are conducted by simulating current shocks and mechanical vibrations in actual use to evaluate performance stability during long-term use. Detailed and accurate reliability test reports are issued after completion.
