Choose Durable MNS Series Insulators from Leading China Suppliers and Factory for Reliable Power Distribution Solutions
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.
