Product Details

MNS series Low-medium voltage electrical insulators introduction

Shape & Design

The column body is cylindrical, which is a relatively traditional design shape for insulators. This simple shape structure, while ensuring insulation performance, is conducive to layout and installation within the power distribution cabinet, providing stable support and insulation for the busbar.

Dimensions & Space

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 sufficient insulation distance and space between the busbar and cabinet body or other components.

Installation Characteristics

There is no place 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.
