ODM Choose Durable MNS Series Insulators from Leading China Suppliers and Factory for Reliable Power Distribution Solutions Factories, Products

The MNS series busbar insulators are designed with a classic cylindrical structure, without a clamping wrench area, necessitating manual installation by skilled workers. With a height range of 20mm to 80mm, these insulators are specifically engineered for medium and low-voltage traditional power distribution cabinets. They are widely used in applications across China, particularly within installations affiliated with the State Grid Corporation of China. As a trusted supplier and factory of high-quality electrical components, we ensure that our busbar insulators meet the rigorous demands of the power distribution industry

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.
