Custom Specialty Cables for Individual Requirements
During the design and operation of machinery, standard cables do not always meet the requirements.
Some projects encounter problems when cables quickly fail due to constant bending, chemical corrosion, or inability to be installed in confined spaces. In more extreme environments such as offshore, underground tunnels, or automated production lines, conventional cables reveal even more limitations.
At this very moment, custom-designed cable solutions become essential – developed based on the specific needs of customers to ensure safety, efficiency, and long-term durability for the system.
Your advantages at a glance
Standard cable solutions are not always suitable for every application. Contact HELU when you need custom-designed cables in cases such as:
- Automated machinery requires electrical cables with a more specialized structure in terms of construction and cross-section.
- Chemical environments, wet environments, or other specialized environments where standard cable products do not meet your needs.
- Electrical cables must be heat-resistant and resistant to corrosion from harmful substances such as oil, acid, alkali, etc.
- The system must simultaneously transmit electricity and signals, or require high EMC noise immunity.
- Limited installation space, requiring small-diameter, flexible, or lightweight cables.
- The project requires compliance with international standards such as UL, CSA, CPR, etc.
- Other requirements...

To provide our customers with high-quality custom cable solutions, our cables must pass rigorous testing at our factory.
FAQs
A standard cable is selected from an existing product catalogue and designed to meet general-purpose specifications. A custom cable, by contrast, is engineered from scratch around the demands of a specific application.
At HELU, that means every element — from sheath compound and core configuration to cross-section, shielding type, armouring, strain relief, lay direction, and conductor resistance — is tailored to match exact operating conditions.
Whether the project calls for steel-sheathed constructions, integrated media hoses, oversized or miniaturised cross-sections, or torsion-rated designs, we have the manufacturing capability to deliver. Additional customization extends to outer sheath colours, packaging formats, and both cable and drum labelling.
Custom cables address technical demands that off-the-shelf products simply cannot meet — for instance, maintaining reliable performance in extreme temperatures or corrosive environments, fitting within very tight installation envelopes, or bundling power, data, and media lines into a single hybrid construction.
Yes. Each design starts with certified, standards-compliant base components that are then modified to suit the target application, ensuring full conformity with the relevant international norms and industry requirements.
Every custom cable begins with a conversation. We work with you to define the technical parameters and propose suitable design options. Our cable engineering team then translates those requirements into a detailed construction drawing, building on field-proven, certified components adapted to your use case.
For volume orders, a pre-production sample is manufactured and submitted for your sign-off before full-scale manufacturing starts. Because engineering and production share a single site, lead times stay short. The finished cable can also be paired with a ready-made assembly or a HELUCHAIN cable carrier system.
Timelines vary with complexity, but co-locating development and production at our Windsbach facility keeps them as short as possible. For larger runs, we first agree on technical parameters, then produce an approval sample. Once you sign off, series manufacturing begins and we commit to a firm delivery date.
There is no fixed minimum — it depends on the cable design and manufacturing setup. For highly specialized constructions the initial run may be larger to justify tooling, but we discuss feasible quantities during the project scoping stage.
Absolutely. Custom cables can be supplied as part of a complete system — pre-assembled with connectors, integrated into a HELUCHAIN drag chain, or delivered as a fully installation-ready cable assembly.
The more detail the better: intended application and environment, required conductor count and cross-sections, voltage and temperature ratings, mechanical loads (bending, torsion, tensile), any approval requirements (UL, CSA, ATEX, etc.), and desired outer diameter or space constraints. Our engineering team can guide you through what's needed during an initial consultation.
