Application & Operating Conditions
Type SHD Flat 2000 V trailing cable solves severe drum-capacity and low-seam clearance constraints on underground AC shuttle cars, continuous miners, roof bolters, and mobile face haulers where circuits require individual metallic phase shielding and grounding without an internal ground-check pilot wire. Its parallel flat profile stacks neatly across level-wind reels without cross-over pinching and flexes effortlessly around small-diameter guide sheaves.
AC Shuttle Cars & Reel Haulage
Flat H × W cross-section packs more linear footage onto compact shuttle-car reels while resisting run-over crushing better than tall round cables in low coal and potash seams.
Continuous Miners & Face Cutters
Individual tinned copper and textile composite phase shields contain phase-to-ground faults immediately in wet, conductive underground headings.
Mold-Cured Integral Web Stability
Vulcanized extra-heavy-duty CPE / Neoprene outer sheath bonds into the inter-core webs to prevent core rolling, corkscrewing, and jacket delamination under high reel tension.
Need Unshielded Flat Cables Instead? For DC shuttle cars or unshielded AC reels, TEBAOFLEX also manufactures 2 kV Type W Flat (2C & 4C) and Type G Flat (2C + Ground) trailing cables per ICEA S-75-381.

Frequently Asked Questions (FAQ)
Technical FAQs on Type SHD Flat vs. Type SHD-GC and flat reel handling.
Why does Type SHD Flat omit the yellow Ground-Check (GC) conductor?
Per ICEA S-75-381, “Type SHD” (without the -GC suffix) designates a shielded heavy-duty cable with grounding conductors only—used on underground machines employing impedance/diode frame-ground monitoring over the power/ground conductors or where reel width restrictions favor a compact 4-element flat profile.
Can TEBAOFLEX supply Type SHD Flat in either black CPE or Polychloroprene (Neoprene)?
Yes. We vulcanize Type SHD Flat in heavy-duty mold-cured black CPE for superior oil, chemical, and thermal-aging resistance, as well as classic Polychloroprene (Neoprene) or extra-tough TPU for specialized shuttle-car fleets.
How is bending radius measured on a flat mining cable?
Bending radius on flat trailing cables is calculated across the minor dimension (thickness H), typically 6 × H over sheaves and reel drums—giving flat cables a much tighter allowable drum core diameter than equivalent-ampacity round cables.
