Exothermic Welding Connections
Comprehensive range of precision-engineered exothermic connection joints including Cable-to-Cable (SICC), Cable-to-Rod (SICR), Tape-to-Tape (SITT), Cable-to-Tape (SICT), Rod-to-Tape (SIRT), and Rod-to-Rod (SIRR) configurations for permanent molecular grounding bonds.
- Complete configurations: Horizontal Cross, Tee, L, Parallel, and Vertical joints.
- Joint code designations: SICC (Cable-to-Cable), SICR (Cable-to-Rod), SITT (Tape-to-Tape), SICT (Cable-to-Tape), SIRT (Rod-to-Tape), SIRR (Rod-to-Rod).
- Forms irreversible molecular copper bonds with electrical conductivity exceeding the conductors.
- Permanent connection eliminates mechanical loosening, corrosion, and resistance degradation.
- Withstands repeated high fault currents and heavy lightning strike discharges.
- Suitable for copper cable, copper tape, solid copper rod, copper bonded rod, GI strip, and steel rebar.
- Designed and tested in compliance with IEEE 837, IEC 62561-1, and IS 3043.

Real-World Finished Weld Quality
Sprexo exothermic welding creates a continuous molecular metallurgical bond that never loosens, oxidizes, or suffers from high contact resistance over time.
Superior Electrical Conductivity
Cross-sectional area of the welded mass exceeds conductor area, ensuring current-carrying capacity > 100% IACS.
Withstands Repeated Fault Currents
Withstands extreme melting temperatures (up to 1083°C) without degradation, unlike mechanical bolted clamps.
Zero Corrosion & Maintenance Free
Completely sealed against moisture and soil chemicals; eliminates galvanic and electrochemical corrosion.
