MERSEN Isolator Porcelain

Mersen High-Voltage Feed-through Bushing Description This is a robust high-voltage bushing, likely manufactured by Mersen (via their HTM subsidiary). It is designed to provide a safe and reliable passage for electrical conductors through panels, enclosures, or transformer walls. The ceramic body offers excellent electrical insulation, while the heavy-duty stainless steel flange ensures a secure mechanical mount. Specifications Manufacturer: Mersen Product Type: High-Voltage Feed-through Bushing Body Material: Ceramic/Porcelain Flange Material: Stainless Steel Mounting: 4-bolt square flange Label Info No product label is visible on the unit itself. Identification is based on associated shipping documentation pointing to Mersen’s subsidiary. Application This component is suitable for use in high-voltage applications such as power transformers, switchgear, capacitor banks, and other power distribution equipment where reliable insulation is critical. Country of Origin Manufactured in France. CO2 Impact Opting for this pre-owned component avoids approximately 3.0 kg of CO2 emissions compared to producing a new one. This saving is equivalent to the emissions from a 15 km car journey. Availability This item is in stock and ready for immediate dispatch.

FAQ What is the typical application for a high-voltage bushing like this?These bushings are primarily used to safely carry high-voltage current through a grounded metal barrier, such as the casing of a power transformer or a switchgear cabinet, preventing electrical arcing to the enclosure. What are the key materials used in its construction and why are they important?It uses a ceramic (porcelain) insulator for its high dielectric strength and resistance to environmental factors, and a stainless steel flange for its corrosion resistance and strong, secure mounting capability. How can I determine the voltage and current rating without a visible part number?Without manufacturer specifications, the rating cannot be determined with certainty. However, a qualified electrical engineer can make an estimate based on physical dimensions, such as the length of the creepage distance on the insulator surface and the diameter of the central conductor. For critical applications, high-voltage testing is recommended. profideals is not an authorized distributor, reseller or representative of the products featured on this website.
