When mobile equipment must run shift after shift in tough environments, the cable that carries its power becomes mission critical. The MYP flexible cable family is engineered to meet that need: combining conductor flexibility, durable insulation, mechanical protection and, where required, electromagnetic screening. This combination delivers long service life for trailing, reeling and movable feeder applications while keeping crews safe and maintenance predictable.
Below is a practical, procurement-focused guide that explains what makes an MYP flexible cable perform in the field, how to choose the correct construction and rating for your application, what to require from suppliers, and how to handle installation and maintenance so the cable achieves its designed life.
Mines, tunnels and heavy industrial plants subject cables to a collection of stresses that ordinary wiring was never designed to survive: repeated bending and coiling, abrasion against rock and metal, chemical exposure from oils or lubricants, and harsh temperature swings. A plain industrial cable typically fails quickly under those combined loads.
An MYP flexible cable, by contrast, starts from the expectation of movement and abuse. Fine-stranded conductors are chosen for bend endurance, elastomeric insulation resists crack formation and thermal aging, and a robust jacket compounds protect against cuts and abrasion. For any mobile power run — whether trailing a loader, spooling on a reeling drum, or feeding a movable transformer — a correctly specified MYP flexible cable reduces unscheduled stoppages and maintenance costs.
When evaluating options, inspect the construction layer-by-layer:
Conductors (flex life): For repeated bending, conductor geometry is everything. Choose fine-stranded copper with an appropriate flex class; in corrosive or wet galleries, tinned conductors are preferable. The conductor stranding must balance ampacity and flexibility — more strands usually means more flex endurance.
Insulation (electrical + mechanical): Elastomeric insulations such as EPR/EPDM are common because they remain flexible across temperature ranges and resist mechanical fatigue. Insulation thickness must meet your voltage class and expected mechanical separation needs.
Screening (EMI and grounding): A metallic screen or braid reduces electromagnetic interference and creates a controlled earth path. This is important when power and control cables run in proximity and where fault detection and grounding strategies rely on predictable screen behavior.
Outer jacket (abrasion & chemical resistance): Jacket chemistry (CPE, neoprene, polyurethane, or halogen-free blends) should be chosen to resist the specific hazards on site — abrasion, oils, chemicals, or even flame/smoke requirements. A jacket’s abrasion index and tear strength are practical metrics to compare.
Optional armor or reinforcement: For zones of heavy impact or crushing risk, consider an armored variant, but be mindful that armor increases weight and reduces flexible handling.
A cable with these properly engineered layers is what clients expect when they order an MYP flexible cable for demanding service.
Not every flexible cable is right for every movement profile. Break your runs into movement buckets and match designs accordingly:
Trailing cable (dragged along): These runs need abrasion resistance and conductor flexibility. A thicker abrasion-resistant jacket and torsion-stable construction extend life.
Reeling cable (spooled/drum): Reeling imposes cyclic bending and spooling shear. Select cables explicitly tested for spooling cycles and observe manufacturer drum diameter recommendations.
Fixed feeder in abrasive zones: Static runs may not flex often but still require protective jackets against abrasion and impact. Consider reinforced jackets or armor in high-risk corridors.
On-board installation (mounted on equipment): Onboard cables must tolerate vibration, heat and occasional flexing. Select compounds rated for higher operating temperatures and vibration endurance.
Selecting the correct MYP flexible cable type for each movement profile is the fastest way to prevent repeated failures.
To avoid ambiguous supplier responses, include measurable technical demands in your RFQ:
Voltage rating and conductor mm² options. (e.g., specify U0/U class and acceptable conductor sizes.)
Conductor stranding class and plating. (state required flex class and whether tinned conductors are needed.)
Insulation and jacket compound grades. (request compound datasheets and compatibility data.)
Minimum bend radius. (specify multiples of outer diameter for spooling and termination.)
Abrasion and tear test results. (ask for abrasion index values or test reports.)
Factory tests and batch traceability. (require insulation resistance, high-voltage dielectric, DC resistance and flex/bend test certificates per reel.)
Marking and reel identification. (demand lot numbers printed on each reel linked to test reports.)
Those criteria turn vendor marketing into verifiable data you can use to compare offers and accept deliveries with confidence.
A dependable supplier should provide:
Detailed product datasheets and typical assembly drawings.
Batch-level factory test certificates attached to each reel.
Material safety and property data sheets (MSDS and abrasion/chemical resistance data).
Recommended termination kits and glands compatible with the jacket chemistry.
Field references or case studies for similar installations.
If a supplier resists providing batch test evidence or material grades, treat that as a red flag — you’ll be the one troubleshooting field failures later.
Even the best MYP flexible cable needs correct handling. Follow these proven practices:
Maintain minimum bend radius throughout routing and particularly at terminations. Tight bends cause internal conductor stress.
Use proper strain relief and gland systems sized to the jacket compound to prevent pull-out and preserve seals.
Route to avoid sharp edges and abrasive contact; where unavoidable, install rollers, sleeves or guides.
Protect spooled cable with correct drum diameters and avoid reversing on small drums.
Seal and protect splices and terminations from moisture ingress and corrosive contaminants.
Applying these measures substantially extends service life and maintains the warranty validity.
A planned program keeps cable networks healthy and predictable:
Scheduled visual inspections — check for jacket cuts, abrasion lines, kinks or deformation.
Electrical testing intervals — periodic insulation resistance and continuity checks to detect early degradation.
Thermography at terminations — detect high resistance joints before failure.
Replacement thresholds — define exit thresholds (e.g., sheath wear depth or insulation resistance limit) to plan replacements before failure.
Proactive replacement during planned outages reduces emergency labor costs and protects production continuity.
In many underground or confined installations, fire and smoke properties matter. If your site requires low-smoke or halogen-free behavior, specify those characteristics and ask for supplier test evidence. Additionally, ensure your grounding, screen bonding and protection coordination are detailed in the cable specification so the installed MYP flexible cable integrates safely with protection schemes.
On a per-meter basis a premium MYP flexible cable may appear more expensive than a generic cord. But when you roll up costs from emergency repairs, lost production, and frequent replacements, the right cable almost always reduces total operating expense. Treat cable purchase as infrastructure investment: durable cable reduces unscheduled downtime, lowers maintenance labor, and boosts overall equipment availability.
Exact cable model / construction requested.
Voltage class and conductor sizes.
Conductor flex class and plating (tinned if needed).
Insulation and jacket compound grades and datasheets.
Minimum bend radius and drum recommendations.
Required factory tests per reel and traceability marking.
Recommended termination accessories and handling instructions.
Lead time, MOQ, warranty and spare reel policy.
Using this checklist makes supplier responses comparable and acceptance testing straightforward.
An MYP flexible cable is not a commodity — it’s a designed assembly that must match your movement profile, environmental hazards and safety expectations. Specify measurable attributes, require batch test evidence, insist on installation discipline, and plan maintenance. Do those things and the cable becomes a predictable asset that supports safe, continuous operation rather than a recurring source of failures.
