Explosion-Proof Bushing MBs Series

Description

The Explosion-Proof Bushing MBs Series is designed for safe and reliable connection between steel pipes and turning points during the installation of electrical wiring systems in hazardous environments. It is widely used in chemical plants, oil refineries, oil exploitation fields, offshore oil platforms, oil tankers, military facilities, and other explosive-risk industrial areas.

This series is engineered to ensure secure cable protection and mechanical stability where electrical lines pass through steel conduit systems. It provides a safe transition point for wiring installations, helping to maintain system integrity in demanding and high-risk environments.

Explosion Protection and Certification

The MBs Series Explosion-Proof Bushing is designed in compliance with international explosion protection standards:

• Ex marking: Ex eb IIC Gb

• Ex tb IIIC Db

These ratings ensure suitability for both gas and dust explosive atmospheres, providing reliable safety performance in Zone 1 and Zone 21 hazardous areas.

Material and Construction

The enclosure is manufactured from high-strength ZL102 copper-free aluminum alloy, offering excellent corrosion resistance, mechanical durability, and long service life. This material is suitable for harsh industrial environments including offshore and chemical exposure conditions.
