Contact Box is a key insulation component used in power equipment to protect dynamic and static contacts and ensure stable electrical connections. It is mainly used in medium and high voltage distribution systems such as switchgear and ring main units. Its core characteristics include: using high-strength insulating materials such as epoxy resin or silicone rubber, which are integrally molded by injection molding or molding process, and have the advantages of arc resistance (withstand short circuit current of more than 31.5kA), aging resistance, high insulation strength (power frequency withstand voltage of 42kV/1min), which can effectively isolate the contact from the external environment and prevent poor contact or discharge failure caused by dust and moisture invasion; In structural design, shielding covers are usually built in to optimize electric field distribution, reduce local discharge, and improve equipment operation safety.

We provide full process services: customizing contact boxes of different sizes and voltage levels (10-35kV) according to customer contact specifications and installation requirements, supporting graphic processing and rapid prototyping development; Strictly follow standards such as GB 3906 and IEC 62271, and ensure product performance meets standards through multiple tests such as partial discharge testing and temperature rise testing; Provide installation guidance and technical consultation to assist customers in improving equipment assembly efficiency and reliability. The company relies on advanced mold development capabilities, automated production lines, and over 10 years of industry experience to provide high-precision and long-life contact box products for customers such as power equipment manufacturers and grid operation and maintenance units, ensuring the safe and stable operation of the power system.
