What We Manufacture

Types of Trailing Cables BMI Manufactures

From underground mine drill trailing cables to steel SMS ladle crane cables — BMI manufactures the complete range of elastomeric trailing cables engineered for each application environment.

 

1. Drill Trailing Cable - Type FTD

Engineered for drill jumbos, continuous miners, and drilling equipment in underground coal and metal mines. Built to withstand continuous dragging on abrasive rock surfaces, wet and chemically contaminated environments with construction conforming to IS 14494 / IEC 60092.

  • Multi-stranded annealed tinned copper conductor (EPR insulated)
  • PCP/CSP inner and outer sheath for maximum chemical and flame resistance
  • Nylon/cotton yarn braiding for abrasion resistance during rock-surface drag cycles
  • ATC screening individually and overall as per specification
  • Conforms to IS 14494 / IEC 60092 single core up to 300 sq mm, multi-core up to 185 sq mm

2. Machine Trailing Cable - Type FT-7

Specifically designed for Load Haul Dumpers, Side Discharge Loaders, and Underground Dump Machines. These cables endure the most aggressive mechanical abuse in mining being run over, crushed, dragged around tight turns, and exposed to mine water, hydraulic oil, and explosive atmosphere conditions.

  • Type FT-7 construction per IS 14494 designed for LHD/SDL/UDM duty cycles
  • Multi-stranded tinned copper with EPR insulation for maximum flexibility in tight headings
  • Reinforced PCP/CSP outer sheath rated for direct vehicular overrun contact
  • ATC combined screening individually and overall per specification
  • Cold-temperature flexible insulation no cold-crack failures in low-ambient workings
  • Conforms to IS 14494 / IEC 60092 with full test documentation supplied on every batch

3. Steel Plant Trailing Cable - HOFR High Heat

Engineered for the unique combination of threats inside steel Secondary Metallurgical Shops: radiant heat pulses from ladles at 1,500°C+, molten metal splatter events, and irregular torsional loading from ladle crane direction reversals. Standard HOFR cables fail in this environment. This design does not.

  • Radiant-heat resistant HOFR jacket compound evaluated for intermittent radiant exposure, not just ambient temperature
  • Splatter-resistant outer jacket formulation distinct from standard flame retardance (IEC 60332)
  • Heavy anti-torsion braiding engineered for irregular ladle crane duty cycles with frequent reversals
  • Separator tapes between all cores — prevents internal friction and corkscrewing under torsional load
  • High-density electrolytic copper stranding with optimised lay angle for cyclic fatigue resistance
  • Available up to 3.3 kV screened and unscreened, armoured and unarmoured constructions

4. EAF / Furnace Trailing Cable - Extreme Torsion

Electric Arc Furnace electrode movements impose the most extreme torsional cycling of any trailing cable application. The lay angle of the core construction must be matched to the specific rotation pattern of the electrode drive. Standard cables experience catastrophic torsional fatigue failure within months.

  • Core lay angle engineered to the electrode rotation pattern unique per installation specification
  • Maximum-density anti-torsion braid continuous extreme-cycle torsional loading exceeds SMS/EOT requirements
  • Rapid thermal shock resistant jacket intense localised radiant heat, not ambient temperature
  • EMI screening layer available where electromagnetic interference levels are significant
  • High-density electrolytic copper fine stranding for maximum torsional fatigue life
  • Available 1.1 kV to 3.3 kV per application requirement screened and unscreened constructions

5. EOT Crane & Heavy OEM Trailing Cable

For EOT cranes, gantry cranes, port handling equipment, and general heavy OEM machinery operating in standard industrial environments. Correctly specified not over-engineered for cost efficiency, not under-built for longevity. The right HOFR construction for a predictable, lower-stress duty cycle.

  • Standard HOFR elastomeric jacket for general industrial chemical and temperature resistance
  • Anti-torsion braiding matched to predictable EOT crane runway duty patterns
  • Consistent cross-section geometry for reel drum diameter and cable travel length
  • BIS certification per applicable IS standard full documentation supplied
  • FRLSH sheath option available for enclosed plant installations, tunnels, and fire-sensitive routing
  • Available in armoured and unarmoured constructions for outdoor / cable tray routing
  • Voltage range 1.1 kV to 3.3 kV single core and multi-core options

6. Composite / Hybrid Trailing Cable

A single trailing cable combining power cores, control cores, and earth conductors in one integrated jacket eliminating multiple cable runs on the same equipment. Commonly specified for complex OEM machinery, tunnel boring equipment, and specialised mining or steel plant machines where cable management space is restricted.

  • Power cores (EPR insulated) + control cores + earth conductor all in one jacket
  • Eliminates multiple trailing cable runs on the same piece of equipment
  • HOFR or PCP/CSP outer jacket per the application environment — FRLSH sheath available for enclosed installations
  • Anti-torsion braiding and separator tapes as standard — engineered for combined mechanical load
  • Custom core count and layout per OEM BOM or equipment specification
  • Available 1.1 kV to 3.3 kV power cores control cores rated to applicable standard
  • Available 1.1 kV to 3.3 kV power cores control cores rated to applicable standard
  • Screened and unscreened control core options within same cable construction
Critical Engineering Mistakes

6 Specification Mistakes That Cause Trailing Cable Failures

Procurement teams and plant engineers frequently face premature cable failures almost always due to specification errors, not manufacturing defects. Here is how BMI prevents these mistakes before dispatch.

 

Specifying by Electrical Rating Alone

Selecting a trailing cable only by voltage rating and conductor cross-section, ignoring jacket compound, torsional architecture, and thermal response. A cable rated identically on paper can fail in weeks or last years depending on these factors.

Using Standard HOFR Cable in SMS / Furnace Zones

Standard HOFR cables are rated for sustained ambient temperature. Inside a steel SMS or furnace bay, the dominant threat is intense directional radiant heat from molten metal — a completely different failure mode that standard compounds cannot survive.

Ignoring Torsional Duty Cycle Differences

Assuming that a cable which works on a standard EOT crane will perform equally on a steel ladle crane or EAF electrode drive. These applications have completely different torsional loading patterns irregular reversals, high-frequency cycles, or matched lay angle requirements.

Patching or Splicing Damaged Trailing Cables

Under production pressure, site teams splice damaged high-voltage trailing cables to keep the shift running. This compromises the insulation system and moisture barrier in wet mine environments or SMS facilities, this significantly increases arc flash and ground fault risk.

Standardising One Cable Spec Across the Entire Plant

Attempting to use a single trailing cable specification for all applications in a facility from maintenance EOT cranes to SMS ladle cranes. A cable optimised for one will be over-specified or critically under-engineered for the other.

Sizing FT-7 Cable by Electrical Requirement Alone Ignoring Mechanical Load on LHD & SDL Machines

A 16 sq mm cable may handle the current, but underground LHD/SDL use demands higher mechanical strength to withstand crushing, dragging, and bending.

Don’t make these mistakes on your next project. Our trailing cable specialists will help you specify the exact right construction compound, torsional design, screening, and compliance before you order.

BMI Cables is one of India’s leading trailing cable manufacturers for underground mining applications, supplying to Coal India subsidiaries including WCL, MCL, SCCL, SECL, and ECL across 24+ states. We manufacture FTD drill trailing cables and FT-7 LHD/SDL/UDM machine cables as per IS 14494 / IEC 60092. Our manufacturing facility is in Bhiwadi, Rajasthan, with a sales office in New Delhi.
 
EPR (Ethylene Propylene Rubber) trailing cable uses EPR as the core insulation material, giving it excellent flexibility, heat resistance, and electrical properties — even in wet and chemically aggressive environments. EPR insulated trailing cables are used in underground mines (coal and metal), steel plants, EAF furnace zones, LHD/SDL machines, EOT cranes, and port equipment. The outer sheath is typically PCP, CSP, HOFR, or FRLSH depending on the specific application environment and flame retardance requirement.
 
FTD (Flexible Trailing Drill) cables are designed for drill jumbos and continuous miners — engineered for the specific mechanical stress of drilling operations including sharp bending at drill rotation points and exposure to drilling fluids. FT-7 cables are designed for LHD (Load Haul Dumper), SDL (Side Discharge Loader), and UDM (Underground Dump Machine) equipment — built to resist vehicular overrun contact, handle tight-radius turns in narrow mine headings, and carry power plus earth conductors per IS 14494 requirements. Both types conform to IS 14494 but have different internal constructions suited to their specific duty cycles. Importantly, FT-7 conductor sizing must account for mechanical loading in addition to electrical current — see our specification guidance section above.
 
Steel plant SMS and ladle crane trailing cables require a specialised HOFR compound with radiant heat and molten metal splatter resistance — standard trailing cables are not suitable. The cable must also have heavy anti-torsion braiding for irregular ladle crane duty cycles, separator tapes between cores to prevent corkscrewing, and high-density electrolytic copper stranding with optimised lay angle. BMI manufactures trailing cables specifically for SMS ladle cranes, continuous casting turret drives, and EAF electrode drives — all with compound and construction matched to the high-heat, high-torsion demands of steelmaking environments. Clients include JSPL, JSW, JSL, and RINL VSP.
 
HOFR stands for Heat, Oil, and Flame Retardant — a compound specification for the outer jacket of elastomeric cables. HOFR trailing cables are required in environments where there is exposure to oils, hydraulic fluids, elevated temperature, and flame risk simultaneously. For standard mining or EOT crane applications, PCP/CSP sheathed cables may be sufficient. HOFR is specifically needed in steel plant environments (ladle cranes, SMS, casting bays) and furnace/EAF zones where the combination of oil, heat, and flame exposure exceeds what a standard rubber jacket can handle. BMI supplies HOFR, PCP, CSP, and FRLSH sheath options — selection depends on your specific application environment.
