ÖLFLEX® UNIPLUS Single Core Cables: What They Are and Why Your Control Panel Needs Them

Open up any well-wired industrial control panel, and you'll notice something — the internal wiring almost never uses the same heavy multicore cable running outside the panel. Inside, it's a different kind of cable entirely: single-core, flexible, and built specifically for the tight, dense wiring environment of a control cabinet. That's exactly the job ÖLFLEX® UNIPLUS cables from LAPP are built for.

This guide explains what ÖLFLEX® UNIPLUS single core cables actually are, what makes them suitable for panel wiring specifically, and how to pick the right size for your application — using the 70 sq.mm and 95 sq.mm variants as real examples.

What Is ÖLFLEX® UNIPLUS, and What Is It Used For?

ÖLFLEX® UNIPLUS is LAPP's range of ISI-marked, PVC-insulated single core cables, manufactured in India specifically for control cabinet wiring. Unlike multicore cables — which bundle several conductors together for running between machines or across a facility — a single core cable carries just one conductor, which is exactly what you want when you're wiring inside a control panel or distribution board, where flexibility, ease of routing, and individual circuit separation matter more than bundling.

These cables are rated for use up to 1100V as per IS 694:2010, making them suitable for a wide range of power and control wiring duties inside panels — everything from feeding busbars and terminal blocks to connecting switchgear components and distribution boxes.

What Makes ÖLFLEX® UNIPLUS Suitable for Panel Wiring Specifically

A few design characteristics make this range particularly well-suited to control cabinet applications:

• Fine-wired copper conductor — built to Class 5 of IEC 60228 and IS 8130, offering good flexibility for routing through tight panel spaces and good electrical conductivity for reliable current-carrying performance.
• Flame-retardant PVC insulation — tested to IEC 60332-1 and IS 10810-53, meaning the cable reduces the risk of flame propagation in the event of a fire, an important safety consideration inside enclosed panels packed with electrical components.
• ISI marking — confirming compliance with Indian standards, which matters for panel builders who need certified components for compliance and audit purposes.
• Fixed installation rating up to +70°C — suitable for the kind of sustained thermal load a busy control panel can generate.
• Easy to assemble — a practical detail that matters a lot when you're wiring dozens of connection points inside a densely packed cabinet.

ÖLFLEX® UNIPLUS 1X70 BK — 70 sq.mm Single Core Cable

The ÖLFLEX® UNIPLUS 1X70 BK (Article No. 4521014U100) is the 70 sq.mm variant in this range, finished in black. A conductor of this cross-section is typically used where a control panel or distribution board needs to carry substantial current — think incoming supply connections, main busbar feeds, or wiring for larger power distribution points within a panel, where a smaller gauge simply wouldn't have the current-carrying capacity needed.

ÖLFLEX® UNIPLUS 1X95 BK — 95 sq.mm Single Core Cable

The ÖLFLEX® UNIPLUS 1X95 BK (Article No. 4521015U100) steps up to a 95 sq.mm cross-section, again in black. This larger conductor size is suited to even heavier current-carrying applications — main incomer connections, high-capacity busbar links, or feeder wiring in panels supplying substantial industrial loads, where you need the extra copper cross-section to keep voltage drop and heating within safe limits.

1X70 vs. 1X95 — How Do You Choose?

The decision here almost always comes down to one thing: the current your specific connection needs to carry. Larger cross-section cables like the 95 sq.mm variant support higher current-carrying capacity, but they're also less flexible, bulkier to route, and more expensive per meter than the 70 sq.mm option. Choosing correctly means:

• Calculating the actual load current for that specific connection point in your panel
• Checking derating factors if your panel runs hot or has multiple cables bundled together
• Leaving a reasonable safety margin rather than sizing right at the calculated minimum
• Confirming your termination points (busbars, lugs, terminal blocks) can physically accommodate the cable size you choose

Undersizing risks overheating and voltage drop under load. Oversizing wastes budget and makes routing inside an already-tight panel harder than it needs to be — so this is one selection decision worth double-checking against your actual load calculations rather than guessing.

Where These Cables Typically Get Used

• Control cabinet internal wiring — connecting components inside panels and distribution boards
• Busbar and incomer connections — where higher current-carrying capacity is needed at the panel's main supply point
• Switchgear wiring — linking breakers, switches, and protection devices within an enclosure
• Distribution box wiring — feeding downstream circuits from a central distribution point

If you're also specifying the switchgear these cables will connect to, our Motor Protection Devices guide breaks down how MCBs, MCCBs, contactors, and overload relays work together in the same panel.

Quick Buying Checklist

• Confirm your load current requirement for the specific connection point
• Choose cable cross-section accordingly (70 sq.mm vs. 95 sq.mm, or other sizes in the range)
• Check voltage rating compatibility (1100V rating covers most panel wiring needs)
• Confirm termination compatibility with your busbars, lugs, or terminal blocks
• Verify color coding requirements for your panel-building standard
• Source from an authorized supplier for genuine, ISI-marked cable with proper documentation

Frequently Asked Questions (FAQ)

1. What is ÖLFLEX® UNIPLUS used for?

ÖLFLEX® UNIPLUS is a single core, PVC-insulated cable designed specifically for control cabinet and panel wiring, including busbar connections, switchgear wiring, and distribution box connections.

2. What is the difference between single core and multicore cable?

A single core cable has one conductor and is typically used for internal panel wiring, while a multicore cable bundles multiple conductors together and is generally used for running wiring between machines or across a facility.

3. What voltage rating does ÖLFLEX® UNIPLUS support?

ÖLFLEX® UNIPLUS single core cables are rated for use up to 1100V as per IS 694:2010.

4. How do I choose between the 70 sq.mm and 95 sq.mm variants?

Choose the cable cross-section based on the actual load current the connection needs to carry — larger cross-sections like 95 sq.mm support higher current-carrying capacity but are bulkier and less flexible to route.

5. Is ÖLFLEX® UNIPLUS flame retardant?

Yes, it is tested to IEC 60332-1 and IS 10810-53 standards, reducing the risk of flame propagation in the event of a fire.

Final Thought

Control panel wiring might not be the most visible part of an electrical installation, but it's where reliability really gets decided — undersized or poor-quality internal wiring quietly causes overheating, voltage drop, and long-term failures long before anything looks obviously wrong. Whether you need the 70 sq.mm or 95 sq.mm variant of ÖLFLEX® UNIPLUS, matching the cable size correctly to your panel's actual current requirements is what keeps that wiring doing its job safely for years.
