Product Description
This DC jumper is a robust power connector cable designed for negative bus and grounding applications in photovoltaic, battery and industrial DC systems. A flexible stranded copper wire provides low electrical resistance and stable current transmission, while high-quality insulation ensures reliable performance under continuous load.
One end is fitted with a tinned copper ring terminal connector for secure bolted connection to busbars, battery posts or chassis ground points. The opposite end uses a matching tinned copper fork terminal connector, allowing quick installation to screw terminals or distribution blocks without removing the screw completely. Yellow insulated sleeves and clear “DC PV-” marking help installers distinguish polarity and connection position on site.
By combining controlled crimping, strain relief and 100% electrical testing, this harness offers dependable performance for demanding DC applications where safety, low contact resistance and long service life are essential.

Applications
DC battery pack connection and negative busbar jumpers in energy storage cabinets
Photovoltaic inverters, combiner boxes and DC PV strings for grounding and return lines
Automotive and commercial vehicles: power distribution, auxiliary battery links and chassis grounding wires
Telecom and server rack power systems, DC distribution units and UPS cabinets
Industrial control panels, power supplies and other electronic equipment requiring reliable ring-to-fork terminal wiring
Precautions
Select appropriate wire gauge and terminal size according to system voltage, current and allowed temperature rise.
Ensure that mating studs and screws match the ring and fork opening dimensions; tighten to the recommended torque to avoid loose electrical connections.
Route the cable to avoid sharp bending, abrasion, hot surfaces or moving parts that could damage the insulation.
Do not exceed the rated voltage or current; apply derating in high ambient temperature or enclosed spaces.
Inspect insulation and terminals regularly; replace the harness if there is visible damage, discoloration or corrosion to maintain safe power transmission.
