Top Quality Hotline Clamps from India
Bronze Hotline Clamps, Hotline Clamps for Liveline Applications
We are one of the leading manufacturers and exporters of Bronze Hotline Clamps from India. We have been supplying Hotline Clamps and other live-line hardware accessories to the world market for many decades. Our Hotline Clamps are engineered for superior conductivity, corrosion resistance, and mechanical integrity in live-line working environments. Used extensively by utility companies, OEMs, and maintenance teams, these clamps allow for temporary or permanent connections to energized lines without interrupting service. Our product range adheres to ASTM B584, IS 319, and ANSI C119 standards, ensuring compliance with international performance norms. Each clamp is precision cast from high-conductivity Bronze alloys and machined using CNC lathes and milling centers. We provide full flexibility in bolt configuration, eye fitting styles, and tongue designs, supported by a 4–6 week turnaround time and reliable customer service.
Product Overview Bronze Hotline Clamps are high-strength, corrosion-resistant mechanical connectors used to join conductors during live-line operations. These are commonly used with hot sticks for temporary grounding, bypassing, or tapping. Each clamp features a swiveling eye bolt and serrated or smooth jaws for conductor engagement. Our models are suitable for conductors from 8 AWG up to 2/0 AWG or custom sizes upon request.
