Zhejiang Longgao Electrical Co., Ltd. is a high-tech enterprise specializing in the research, development, and manufacturing of precision‑formed components for high‑voltage load switches. Our main products include Schneider‑type contacts, 36 kV load switch contacts, and ABB‑type gas‑insulated switchgear contacts. We are equipped with state-of-the-art production facilities both domestically and internationally, supported by substantial manufacturing capacity. Our core business focuses on cold forming of custom metal parts. Components produced via cold‑forming processes exhibit a denser microstructure, superior surface finish, and a hardness exceeding HB 110. These parts require no further mechanical machining, achieving a surface roughness of Ra 1.6 or better, thereby significantly extending their service life.
