DLO Cable Classification: DLO designation meaning: DLO = Deep Level Operations (primary interpretation) Alternative: Diesel Locomotive Overhead (secondary) Context: Used extensively in South African and Australian deep mines where locomotive-hauled trains move ore underground Power supply: 2000V AC fed overhead to locomotive pantograph Deep Level Operations (mining context): Depth: >2,000 meters (6,500+ feet) below surface Pressure: 200+ atmospheres (extreme hydrostatic) Temperature: Geothermal heating to +35–40°C at depth (before cooling) Moisture: 100% relative humidity (saturated conditions) Chemical exposure: Sulfides, nitrates, acidic water Cable requirement: Must withstand extreme environmental stress DLO 2000V: Engineered specifically for these conditions 2000V voltage class significance: Why 2000V (not 1000V or 10kV)? - 1000V: Insufficient for long underground raceways (voltage drop) - 2000V: Sweet spot for deep mine distribution (good efficiency) - 10kV: Overkill for mobile equipment, insulation too thick Power efficiency at depth: P_loss = I²R per kilometer of cable run At 2000V, current = P / (2000 × √3) = 70–80% lower than 240V Over 5 km underground run: Voltage drop acceptable Voltage stress on insulation: Peak voltage (AC peak): 2000 × √2 / 1.414 ≈ 2.8 kV peak Test voltage: 4 kV (1.4× peak, safety margin) Partial discharge inception voltage (PDIV): >5 kV (safe margin) Single-core requirement: Mining locomotives: Three single-core cables run overhead in catenary Reason: Parallel path allows independent cable routing Mechanical advantage: Individual cables can flex, bend independently Installation: Easier to handle than 3-core bundle underground Application: One cable per phase (L1, L2, L3) + neutral if needed Typical setup: 3 × 2000V DLO cables for 3-phase power to locomotive

FLEXIFESTOON® SEOOW YELLOW represents FeiChun's entry into the low-voltage festoon and temporary power market. The nomenclature requires careful explanation to distinguish this product from the high-voltage FLEXIDRUM series: FLEXIFESTOON Product Nomenclature: FLEXIFESTOON® = Product family name Flex = Flexible (emphasis on bending & handling) Festoon = Strung overhead in continuous runs (typical festoon lighting application) SEOOW = Industry-standard designation S = Service cord (temporary, not permanent installation) E = Elastomer jacket (flexible sheath) OO = Oil-resistant conductor insulation (TPE qualifies as oil-resistant) W = Weather-resistant sheath (water, ozone, UV resistant) SEOOW is defined in: UL 62 (Standard for Flexible Cords and Cables) CSA 22.2 No. 49 (Canadian equivalent) NFPA 70 National Electrical Code (NEC) Article 400 YELLOW designation: Color: RAL 1021 (traffic yellow, high visibility) Safety significance: Yellow cords attract attention in job sites Practical purpose: Easy to identify, prevent trips/entanglement Contrast with FLEXIDRUM series: FLEXIDRUM (High-Voltage MV Cable): Voltage: 3.6 kV to 20/35 kV (power distribution) Temperature: −40 to +80°C (standard industrial) Application: Mobile mining/tunneling equipment (capital-intensive) Size: Large diameter, heavy (3–12 kg/km) FLEXIFESTOON (Low-Voltage Service Cord): Voltage: 600V (light/power temporary use) Temperature: −60 to +105°C (extreme environmental range) Application: Festoon lighting, temporary site power, outdoor events Size: Small diameter, lightweight (0.05–0.3 kg/m) Cost: Consumer/contractor-grade (not specialty industrial)
