Ready to use Proven ProTect HV cables for reliable protection in heavy-duty applications.

Whether in commercial vehicles, buses, construction machinery, agricultural vehicles, or the maritime sector – our ProTect HV cables provide a robust solution for harsh environments and extreme mechanical stress, while increasing the level of automation in HV cable assembly production. Factory-wrapped with Coroplast wire harness tape, the cables are precisely tailored to your requirements and reliably protect against abrasion and damage – both during installation and in operation.

With years of experience in series production for leading automotive manufacturers, Coroflex products stand for proven quality and maximum safety. Another advantage: the cables are delivered ready-to-install on reels, already equipped with the proven Coroplast Tape adhesive tapes. This eliminates double inventory, reduces work steps, and thereby saves assembly time, costs, and handling effort.

At a glance Your advantages with our ProTect High-voltage cables

  • Enhanced operational safety:
    The wrapping reliably protects the cable against abrasion and mechanical damage – up to abrasion class G, even under the harshest conditions.
  • Ready for immediate use:
    Factory-wrapped with Coroplast Tape cable wraps, eliminating the need for separate wrapping processes – for shorter assembly times and lower process costs.
  • Tailored protection:
    Wrapping is optimized for each application with perfectly matched Coroplast Tape cable wraps – ensuring targeted protection and the right performance in every situation.
  • Easy installation:
    The proven flexibility of Coroflex HV cables allows for tight bending radii, even with ProTect HV cables.
  • Sealed and reliable:
    The trusted sealing properties of Coroflex HV cables against moisture ingress in HV connectors are maintained at a high level with ProTect HV cables.
  • Cost-effective and automation-friendly:
    ProTect HV cables reduce inventory, eliminate extra machines and manual wrapping processes – increasing automation and lowering effort and costs.
  • Temperature-resistant and efficient:
    With temperature class T180, conductor cross-sections and cable weights are reduced while maintaining high thermal stability under peak loads.
  • Future-proof tested:
    Validated according to LV 216 and ISO 19642, as well as DNV approval for maritime applications – ensuring reliable quality and long-term safety.

ProTect High-voltage cables – product flyer

Discover everything you need to know about the construction, features, and applications of our ProTect HV cables. The product flyer provides information on abrasion and temperature classes, tested standards, and the benefits of Coroplast Tape wrapping in heavy-duty applications.

Flexible, safe, certified Why ProTect is the smart alternative to conventional protection systems

The advantages of silicone HV cables are fully retained

Silicone HV cables offer significant advantages compared to cross-linked HV cables (e.g. XPE, XPO) in terms of weight, installation space, cost, sealing properties, and bending radii. The use of conventional protection systems like corrugated conduits, braided sleeves can lead to increased costs, greater space requirements, and reduced automation levels. With Coroflex ProTect HV cables, we combine the benefits of silicone HV cables with those of Coroplast cable wraps. We reduce manufacturing costs and increase automation levels in HV cable assembly production, while simultaneously minimizing space requirements and allowing for the tightest bending radii.

Targeted protection with Coroplast wire harness tape

For applications requiring enhanced protection, silicone cables are wrapped with Coroplast wire harness tape up to abrasion class G. The wrapping maintains the flexibility of the silicone, reliably protects against abrasion or cutting stress, and thereby extends the lifespan of the entire cable system.

Clean processing – residue-free

The specially developed application method ensures that no adhesive residues are left during wrapping, allowing all downstream processing steps – from cutting to assembly – to be performed without restrictions. This enables ProTect to integrate smoothly into existing production lines and supports stable, automatable manufacturing

Two-layer design for every application

Each ProTect covering consists of two precisely matched layers suitable for all cable types and designs. Depending on the requirements, different Coroplast Tape combinations are used:

  • Coroplast 837 X / 832 MPX: increased abrasion resistance
  • Coroplast 8579 X + 837 X / 832 MPX: increased abrasion resistance and sound-dampening
  • Coroplast 512 + 837 X / 832 MPX: increased abrasion resistance and chemical resistance, e.g., against battery acid

This allows cable systems to be precisely adapted to mechanical and chemical requirements – an advantage rigid systems cannot offer.

Optional variants for extreme requirements

For applications with particularly high mechanical or chemical stress, additional Coroplast wire harness tape combinations are available – for example, for even stronger abrasion protection or enhanced chemical resistance.

Temperature-resistant and practical

Compared to corrugated conduit solutions, ProTect achieves significantly higher temperature classes up to T180, improves derating behavior, and remains flexible and easy to install. In addition, bulky protection systems are eliminated – simplifying assembly and reducing space and weight

Proven quality and system integration

Our HV cables meet the requirements of LV 216 and ISO 19642 – both standards recognized by OEMs as benchmarks for electrical safety and long-term durability. DNV approval for maritime applications demonstrates suitability even under extreme environmental conditions. ProTect is systemically approved for all these cables. For unshielded HV cable assemblies in maritime applications, Coroflex ProTect HV cables are the specified solution.

The video shows how the BERI.CO.TAPE system, developed by Coroflex and Rittmeyer, automatically removes the protective tape — precisely, cleanly, and without damaging the silicone layer. This solution makes the further processing of ProTect cables faster, safer, and consistently reproducible.
