Wire stripping machine for 70mm² electronic photovoltaic wire

　　When it comes to stripping 70mm² photovoltaic cable, it’s a completely different challenge compared to ordinary small wires. The cable is thick, packed with fine copper strands, and covered with tough insulation designed to withstand high temperatures and long-term UV exposure. Many photovoltaic cable jackets are extremely hard, so a standard wire stripping machine often struggles — too little pressure leaves the insulation unfinished, while too much pressure can easily damage the copper conductor.

　　What makes photovoltaic cable even more demanding is the delicate structure of the copper strands inside. Even slight compression can leave marks or scratches on the conductor surface. In the renewable energy industry, wire harness quality standards are becoming stricter every year. Damaged copper strands may later lead to overheating, unstable conductivity, or poor terminal connections.

　　That’s why processing 70mm² solar cable requires a heavy-duty automatic wire stripping machine designed specifically for large cross-section cables.

　　A good feeding system is critical. Machines built for 70mm² cable usually use a multi-belt feeding structure instead of traditional pressure rollers. This allows the cable to move smoothly without deformation, especially when processing photovoltaic cable, silicone cable, or other high-temperature wires.

　　Power and torque also matter. A 70mm² cable is stiff and heavy, and weak drive systems can easily slip during feeding. Reliable machines are typically equipped with 8-wheel or 12-wheel drive systems, sometimes with synchronized dual-side feeding control, ensuring stable wire movement and clean stripping results.

　　For manufacturers working with EV wiring harnesses and solar energy storage cables, data storage and program memory have become essential features. One day the operator may process 50mm² cable, and the next day 70mm² cable. Different cable sizes require different pressure settings, blade depths, and stripping lengths. Machines with touchscreen controls and programmable memory save a huge amount of setup time and reduce constant manual adjustments.

　　Rotary blade technology is another important feature, especially for shielded or multi-layer photovoltaic cables. High-end stripping machines can use rotary cutting systems and multi-layer stripping functions to process outer jackets, foil shielding, and braided shielding layers in a single operation.

　　To be honest, 70mm² photovoltaic cable is no longer considered a “light-duty” application. A machine capable of processing this type of cable consistently should deliver several key advantages:

　　• Strong feeding force without cable slippage

　　• Precise stripping without damaging copper strands

　　• Accurate cutting lengths with high batch consistency

　　• Clean stripping edges without tearing insulation

　　• Belt-driven feeding to protect cable shape

　　• Capability to process hard insulation and high-temperature cables

　　For this kind of heavy-duty photovoltaic cable processing, the WG-9850 Large Cross-Section Rotary Wire Stripping and Cutting Machine is highly recommended.
