Products

UP TO 145 kV -
Electrical Connectors

Electrical connectors for medium to high voltage systems up to 145 kV provide reliable power distribution for substations, industrial facilities, railways, and renewable energy projects. These precision-engineered aluminum connectors feature weather-resistant design and comply with IS/IEC standards for maintenance-free operation. The complete range includes TEE connectors, parallel connectors, terminal connectors, bus couplers, insulator clamps, spacers, and grounding solutions designed for superior performance in critical transmission applications.

UP TO 500 kV -
High Voltage
Electrical Connectors

Extra high voltage connectors for 500kV transmission networks deliver uncompromising performance in national grids, major substations, inter-state corridors, industrial complexes, and HVDC stations. These heavy-duty aluminum connectors feature enhanced current capacity, superior corona resistance, and precision manufacturing to withstand extreme electrical, environmental, and mechanical stresses. The specialized EHV range includes TEE connectors, heavy-duty parallel connectors, reinforced terminal connectors, expansion-capable bus couplers, rigid post insulator systems, precision spacers for bundle conductors, and comprehensive grounding solutions – all meeting stringent performance and safety requirements of critical transmission infrastructure.
