HT/LT Panels

HT Panel

“Sudhir is a leading Panel manufacturer in North India and an Alliance partner of Schneider.Our range offer state of art switchgear for 11 & 33kV with cutting edge technologies in VCB & SF6 upto 1500MVA fault levels.”

HVX is the latest range of vacuum circuit breakers. It offers proven state-of-the-art design to meet to specification for power switching devices in air-insulated switchgear upto 36 kV. HVX brings a valuable solution to your project

“We have brought together the combined experience of our partner Schneider Electric to bring you the latest technology with time – tested and proven reliable design.

This latest addition to our range of vacuum interrupters reinforces our technological position as vacuum switching market leader. Thanks to the improved contact design, our interrupters provide unrivalled performance for their reduced size. Operating mechanisms have been simplified to increase reliability and give extended life with very low maintenance. Instead of the traditional spring operating mechanism, HVX decreed a singIe-shaft system and only one torsion spring, reducing the number of parts an increasing the reliability. The HVX panel meets the latest requirements of IS and ANSI standards

Technical Specifications

LT Panel

Ranging from 11 - 33 kV

Foremost in quality of workmanship and investment in “state of art” technology to manufacture world class LT Switchboards, we have established ourselves as a symbol of quality and innovation in this field.

In recognition of its world-class quality standards we have been awarded with the ISO 9001-2000 certification.

The Panels have been successfully tested at CPRI to withstand short circuit levels of 50/70 & 100 KA with ACB, IP 54, 55 & 65 degree of protection & Temperature rise as per international standards.

The Design and Engineering department is well equipped with Computer Aided Design (CAD) systems and drafting facilities for accurate and quick preparation of design & execution.
