Ladle Transfer Car & Steel Mill High-Temperature Reeling Cable (0.6/1 kV)

Steel mill ladle transfer cars, scrap charging bogies and slag pot carriers run on floor tracks directly beneath teeming ladles, basic oxygen converters and electric arc furnaces, where their motorized or spring-driven cable reels face intense thermal radiation, hot scale, molten metal splash and frequent start-stop reversing. Standard PVC or ordinary rubber reeling cables rapidly harden, crack or suffer core corkscrewing in this melt-shop environment.

Jiangsu Tebaoflex Special Cable Co., Ltd. holds valid ISO 9001:2015 quality management certification (certificate no. 244-24-QI-17425-R0-Q, valid through 2027-12-17) whose certified production scope explicitly names ladle transfer car cables (钢包车电缆). Two thermal grades are supplied for 0.6/1 kV transfer car reels: Type LTR-90/110 (+90 °C/+110 °C HEPR insulation with heavy-duty flame-retardant polychloroprene 5GM5 outer sheath and glass-fibre heat barrier) for standard ladle car tracks, and Type LTRS-180 (+180 °C tear-resistant silicone/fluorosilicone elastomer system with braided glass-fibre/aramid reinforcement) for extreme radiant-heat zones.

Both constructions use finely stranded Class 5 tinned copper conductors to prevent copper oxidation at elevated temperatures, a short-pitch core lay around a heat-resistant central filler, an open-weave aramid anti-torsion braid and a tough outer sheath that resists abrasion against steel guide rollers and floor trenches.

Specify your ladle transfer car motor power, control core count, ambient radiant temperature near the reel, travel distance and drum diameter with your enquiry. TEBAOFLEX manufactures custom ladle car reeling cable lengths from a 50 m minimum order quantity with a standard lead time of 7–45 working days.

For related steelworks hot-zone power feeds and heavy industrial drum reeling cables, compare these specifications: Stacker-Reclaimer & Bucket-Wheel Excavator Drum Reeling Cable (0.6/1–35 kV) (for heavy stockyard and raw-material yard drum reeling up to 35 kV); EAF Water Cooled Cable (for water-cooled high-current electric arc furnace secondary delta-closure connections). Verify radiant heat exposure, molten-splash protection, and drum torque before ordering.

Construction

The representative construction illustrates 0.6/1 kV 4G35 mm² Ladle Transfer Car High-Temperature Reeling Cable: four Class 5 flexible tinned-copper cores (three phase cores in black, blue and brown plus one green/yellow protective earth core) insulated with high-temperature elastomer, cabled in light-grey heat-resistant inner bedding, wrapped with a thermal-barrier glass-fibre tape and anti-torsion aramid braid, and enclosed in a heavy-duty black heat- and splash-resistant thermosetting rubber outer sheath.

Applications

Select Grade LTR-90/110 for floor-trench and shielded drum reels on ladle and scrap transfer cars, or Grade LTRS-180 where the cable reel is exposed to continuous ambient temperatures up to +150 °C / +180 °C near molten metal.

• Motorized and spring-driven cable reels on steel-mill ladle transfer cars, tundish cars and hot-metal torpedo cars.
• Slag pot transfer bogies, scrap basket transfer cars and furnace charging cars in EAF and BOF melt shops.
• Continuous casting run-out table transfer cars, billet handling cranes and soaking-pit cover carriages.
• Foundry, forging and heat-treatment furnace transfer vehicles requiring combined power (4G/5G) or multi-core control (7G–19G) reeling cables.

For melt-shop rail transfer cars, slag-pot carriers, and hot-zone cable reels, consult these engineering references: Flat Cable for an Oxy-Cutting Car Travel Cycle — Steel Plant, Egypt (for continuous-casting oxy-cutting car travel cable engineering in steelworks); TROMMELFLEX KSM-S & (N)SHTOEU-SMK Spring & Motorized Drum Reeling Cable (0.6/1 kV) (for standard-ambient spring-driven and motorized transfer car drums at 0.6/1 kV). Check peak ambient temperature, rail travel distance, and minimum bending radius for your mill track.

Specifications

Listed current ratings for Grade LTR-90/110 are referenced at +30 °C ambient air and +60 °C elevated steel-mill ambient air; for Grade LTRS-180 silicone-insulated cables, high-temperature derating allows continuous operation up to +150 °C ambient.

ISO 9001:2015 certificate 244-24-QI-17425-R0-Q is held by Jiangsu Tebaoflex Special Cable Co., Ltd. and explicitly names ladle transfer car cables (钢包车电缆) in its certified production scope.

When installed on multi-layer cylindrical transfer-car reels in high-ambient melt shops, combine the elevated-temperature factor with the wound-layer reel derating factor.
