Flexible multi-strand tinned copper lead wire engineered for string jumpers and solar array junction box connections.
Sumati Photovoltaic Wire is purposefully engineered for demanding intra-module string jumpers, cross-module interconnect bridges, and high-reliability junction box termination in modern commercial and utility-scale solar installations. Constructed from Class 5 flexible multi-strand electrolytic copper conductors (TU1/C11000 grade), our PV wires combine maximum electrical conductivity (> 100% IACS) with superior bend fatigue endurance and vibration damping under high-velocity wind loads.
To ensure zero atmospheric oxidation and galvanic corrosion over multi-decade operating horizons, each individual copper strand receives a continuous hot-dip tin plating layer (1.5–5.0 µm). This uniform tin coating creates a robust diffusion barrier that prevents atmospheric oxygen, moisture, and sulfur from forming non-conductive copper oxides, maintaining ultra-low contact resistance even in aggressive marine and industrial environments.
Insulated with electron-beam cross-linked polyolefin (XLPO) copolymer compounds, Sumati PV wires withstand continuous operating temperatures from $-40^\circ\text{C}$ to $+120^\circ\text{C}$ and short-circuit temperatures up to $+250^\circ\text{C}$. The insulation matrix exhibits exceptional resistance to intense ultraviolet radiation, ozone cracking, micro-tearing, and hydrolysis over a 25-year service lifetime.
With wetting balance test zero-cross times under 1.0 second and excellent solder alloy compatibility, our PV wire ensures rapid, void-free soldering to junction box terminal lugs and busbar cross-connects, dramatically reducing production cycle times in automated solar module assembly plants.
