Terminal Connectors - Rigid type, Expansion type, T-Connectors, P G Clamps, Inter Connector, Corona Bell, Welding Sleeve, Rigid Spacers, Flexible Spacers, Elbow Connector, Junction Connector, Support Connector. Terminal Connectors used in sub-stations can be mounted on different equipment like Isolator (Disconnector), Transformer, CT, CVT, BPI, LA, etc.. for different IPS Alu. Tube sizes and conductor configrations (Single/Twin/Triple/Quad/Hexa/Octa). The connectors are tested as per IS: 5561 and Spacers as per IS: 10162 Standards. Clamps and Connectors are made of Aluminium Casting (LM6/LM25 as per BS 1490 or Gr 4600 as per IS: 617) suitable for different voltage ratings upto 1200kV for conductor configuration in Single/Twin/Triple/Quad/Hexa of all conductor / IPS tube sizes and sub-conductor spacings.
