Recommended Layered Wire Stripping Machines for EV New Energy Cables

Anyone who has worked with electric vehicle (EV) and new energy cables has probably had the same feeling: you’re not really stripping a wire. You’re taking apart a carefully engineered cable structure.

At first glance, these cables simply look thick and heavy. But once you actually start working with them, they can be surprisingly difficult to process.

The outer layer may be a thick jacket, followed by high-voltage insulation, shielding layers, braided wire, or other composite materials. Each layer has its own job — high-voltage protection, electromagnetic shielding, heat resistance, and mechanical protection. But when it comes to stripping, every layer becomes a point where things can go wrong.

The biggest concern is damaging the conductor.

EV cable conductors are often relatively soft, while the insulation layers can fit tightly around them. If a stripping blade goes even slightly too deep, it can leave a small, hidden nick in the conductor. The damage may not be visible during production, but it can become a serious problem after years of operation. That is one of the issues EV harness manufacturers are particularly careful about.

Then there is the challenge of separating the layers.

With a conventional wire, stripping can often be as simple as making one clean cut and removing the insulation. EV cables are different. In many applications, the cable has to be processed layer by layer.

One job may require the inner insulation to remain intact. Another may require the conductor to be fully exposed. In either case, the stripping length, cutting depth, and transition between layers need to remain consistent from one cable to the next.

For high-voltage coaxial cables and other multi-layer cable constructions, the process can involve more than nine distinct layers. At that point, the job is far beyond what a conventional wire stripper is designed to handle.

What EV and new energy cable production really needs is not simply a more powerful machine. It needs a machine that knows where to stop.

A good multi-layer cable stripping machine should allow operators to set the required parameters once and then let the machine repeat the process consistently. The blades should not simply cut through the cable. They should be able to work at controlled depths, processing each layer according to its structure.

The parameters should also be saved and recalled when needed. When switching between different cable types, operators should not have to start from scratch, repeatedly testing and adjusting until they get the result right.

After stripping, the shielding layer should be clean and properly separated, while the conductor should remain completely intact. The result should come from controlled processing — not from luck.

In that sense, a good stripping machine is more like a reliable production worker than a cold piece of equipment.

For EV high-voltage cables and new energy cable harnesses, I would personally lean toward Guangdong YinGang.

What stands out about YinGang equipment is its stability. It is not simply a machine with an impressive list of specifications that looks good on paper but becomes difficult to operate on the production floor. It is designed as a production machine that can be used continuously, with particular attention to multi-layer stripping, shielding treatment, and consistent processing results.

When you are manufacturing new energy cable harnesses, the most important thing is not simply buying the cheapest equipment. It is maintaining consistent product quality over thousands of processing cycles.

Sometimes, choosing the right stripping machine can be more valuable than adding several workers to the production line.
