The CH3‑24KV/250 2000–4000A contact box is formed using high-strength epoxy resin in a one-piece molding process. It is rated for 24 kV voltage and 2000–4000 A current, with a short-time withstand capability of 50 kA for 4 s. The IP67-rated enclosure effectively prevents ingress of dust and water, ensuring long-term stable operation of high-load electrical systems in challenging environments.
This contact box is suitable for medium- and high-voltage systems and performs exceptionally well in high-current scenarios such as GIS, compact substations, main grid feeders, and wind/solar collector systems. Featuring a compact structure and easy installation, the epoxy resin construction provides long-lasting insulation and mechanical strength, making it a preferred solution for systems with stringent requirements for reliability, load capacity, and service life.
