Invention patents and utility model patents

Tianjin Xingda Electric prioritizes independent R&D and intellectual property protection. The company holds a series of invention patents and utility model patents covering core transformer accessories, including transformer bushings, desiccant breathers, oil‑level indicators and related power‑component structures．

With these patented designs, Xingda’s transformer accessories perform reliably under harsh working environments, including high temperature, heavy humidity and coastal salt‑fog conditions. The risk of oil leakage, insulation degradation and component failure is effectively reduced.
