Line Fittings | TY Series Compression Aluminium T-Connector Clamp (Hydraulic Crimp T-Junction) is a hydraulic compression (crimp) type aluminium T-connector clamp designed for permanent, high-current branch connection on high-voltage and extra-high-voltage overhead transmission lines. Manufactured from high-purity seamless extruded electrical aluminium tube, ensuring seamless electrical conductivity, minimal resistance and superior thermal withstand capability.
The T-connector provides dependable mechanical holding force and low-resistance electrical current transfer across demanding outdoor overhead line environments. The contact grooves are precisely contoured to match conductor curvature, ensuring uniform pressure distribution, preventing strand damage, and maintaining minimal temperature rise under full rated operating currents and heavy short-circuit fault conditions.
Key Design & Performance Highlights:
Applications: Widely installed for 110kV to 500kV transmission line mainline tee-branching, substation busbar takeoffs, heavy-current jumper loops and permanent non-tension conductor taps in 110 kV to 500 kV transmission lines and power grid substations.
