Durable MNS Series Busbar Insulators for Medium and Low-Voltage Applications | China Suppliers & Factory
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)
What materials are MNS series support insulators made of?
They are manufactured using high-quality unsaturated resin (BMC/DMC) combined with brass or steel inserts, which ensures superior electrical insulation and mechanical strength.
What is the working temperature range for these insulators?
MNS series electrical insulators are designed to operate reliably in harsh environments, with a working temperature range of -40℃ to 140℃.
Are these products compliant with environmental and safety standards?
Yes, our low-medium voltage electrical insulators meet ROHS 2.0 environmental requirements and are certified with CE, REACH, ELV, and SGS.
Can I customize the dimensions and thread sizes?
Absolutely. We offer customization options for colors, insert materials, and dimensions (heights ranging from 20-80mm and thread sizes from M5-M12) to match your specific cabinet layouts.
What are the flame retardant properties of the MNS series insulators?
The insulators achieve a UL94 V0 flame retardant grade (at 3mm thickness) and can withstand hot wire temperatures up to 960℃, ensuring optimal safety in power distribution cabinets.
