CE Certification Choose MNS Series Insulators for Lasting Durability Exporters, Products

The busbar insulators of the MNS series feature a traditional insulator design. The column body is cylindrical, and there is no area suitable for a clamping wrench. During the installation process, manual installation by workers is required. Generally, the designed height of the product is between 20mm and 80mm. This product is mainly applied in medium and low-voltage traditional power distribution cabinets, such as those of the State Grid Corporation of China.

Product Description

MNS Series Low-Medium Voltage Electrical Insulators Introduction

Shape: 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.

Dimensions: 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.

Installation Characteristics: 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.
