Bus ducts for high-voltage current transmission. 

These prefabricated and standardised busbars are designed to carry a current of 1000 to 4000 A at high voltage up to 36 kV. Its main areas of activity are supplying the primary side of HV/LV transformers in steelworks furnaces or connections in HV substations on electricity production sites or in industry.

• Modular ISPB bus ducts delivered ready to install;
• Space-saving;
• Copper or aluminium conductors;
• Double insulation with resin and outer sheath: touch protection;
• Precise routing for each project with 3D CAD drawing;
• High dynamic and thermal short-circuit resistance;
• No maintenance of the cast joints: no loosening of the screws possible;
• Suitable for severe installation conditions (climate, humidity, corrosive atmosphere)…
