MNS Series Insulators from China Factory: Durable Solutions by Reliable Suppliers for Power Distribution
MNS series Low-medium voltage electrical insulators introduction
The column body is cylindrical, which is a relatively traditional design shape for insulators. This simple shape structure, while ensuring the insulation performance, is conducive to the layout and installation within the power distribution cabinet, providing stable support and insulation for the busbar.
The general designed height of the product is between 20mm and 80mm. According to the space of different power distribution cabinets and the layout requirements of the busbar, insulators with appropriate heights can be selected to ensure that there is sufficient insulation distance and space between the busbar and the cabinet body or other components.
There is no place that can be adapted to a clamping wrench, and manual operation is required during installation. This requires installers to have certain operation skills and experience to ensure the accuracy and firmness of the installation.

Frequently Asked Questions (FAQ)
MNS series support insulators support an AC operating voltage range of 800V to 3200V and a DC working voltage range of 1100V to 4500V, making them well-suited for low to medium voltage applications.
The body is molded from high-grade unsaturated resin (BMC/DMC), and the threaded inserts are made from robust brass or steel to guarantee mechanical and electrical durability.
They have a wide working temperature range of -40℃ to 140℃, a flame retardant grade of UL94 V0 (3mm), and can withstand a hot wire temperature of up to 960℃.
Yes. While standard heights range from 20mm to 80mm, diameters from 20mm to 60mm, and thread sizes from M5 to M12, custom colors, insert types, and material formulations are fully supported.
The MOQ is 100 pcs. The products comply with ROHS 2.0 and are certified under CE, REACH, ELV, SGS, UL, and PSCR, produced in facilities certified to ISO9001, ISO14001, and IATF16949.
Due to the cylindrical column body design without flat wrench clamping slots, manual installation is utilized to ensure precise alignment, secure fastening, and optimal support for the busbars within power distribution cabinets.
