从China供应商批量进口400v-40.5kv Switch Element

The 400V-40.5kV switch element from Ningbo Huayuan Electric And Machine Industry Co.,Ltd. is a medium-voltage switching device designed for electrical distribution systems. It operates across a voltage range of 6kV to 40.5kV, with variants including the Fn26 series SF6 on-load switch and vacuum on-load switch, both built for reliable performance in industrial and utility applications. The unit is engineered for outdoor use, with a focus on durability and ease of installation.

Switch elements in this voltage class typically use SF6 gas or vacuum as the switching medium, offering high dielectric strength and low maintenance requirements. The Fn26 series SF6 switch is a common design for outdoor installations, with standard features such as manual or motorised operation, visible break contacts, and interlocking mechanisms for safety. Vacuum switches, on the other hand, are often preferred for their compact design and long electrical life, with typical ratings up to 40.5kV and 630A continuous current.

This switch element is used in substations, power plants, and industrial facilities where medium-voltage switching is required for load management or fault isolation. It is sourced from Ningbo, Zhejiang, a key manufacturing hub for electrical components in China. Buyers should confirm the specific switching medium, rated current, and whether the unit includes auxiliary contacts or remote operation capabilities. Packaging is typically designed to protect the switch from mechanical damage and moisture during transit.

Ningbo Huayuan Electric And Machine Industry Co.,Ltd. is located at 323 Ningchun Road in Ningbo, Zhejiang, a city with a strong industrial base for electrical and machinery products. The company specialises in electrical components, including switchgear and switching elements, catering to both domestic and international markets. Its harbor trust tier indicates a baseline level of export verification, though the profile does not provide details on production scale or certifications.

The supplier’s current response rate and average response hours are recorded at zero, which may indicate limited online engagement. Buyers are advised to use alternative communication methods, such as direct email or phone, to confirm technical specifications, lead times, and trade terms. The company does not list specific certifications or client references in the provided data, so these should be requested directly to assess reliability.
