    Explosion-proof flexible reinforced cable elements of the MGM, MGMA series

    Explosion-proof flexible reinforced cable elements of the MGM, MGMA series Explosion-proof flexible reinforced cable elements of the MGM, MGMA series - image 2

    Product Description

    MGM/MGMA are explosion-proof, flexible, reinforced metal conduits made of highly corrosion-resistant stainless steel. They are used for laying cable routes between vibration-prone areas (electric motors, pumps, fans, etc.), as well as for protecting weak cable systems and fiber optics in hazardous areas. The metal conduit with metal braiding provides reliable protection and flexibility, while rotating fittings simplify installation and compensate for thermal and seismic movements.

    Advantages

    • Rotating fittings facilitate installation, prevent cable twisting and compensate for axial displacement.
    • Extended operating temperature range (–60 °C…+150 °C), suitable for use in aggressive environments.
    • Effective dust- and moisture-proof design (up to IP66–IP68) with electromagnetic shielding (55 dB/1 MHz)
